This course will give you an introduction to SKF bearings and consists of three sections: Functions and parts,Applications and bearing types,and Designations.Module 1: Functions and partsWhy bearings?Bearings are an essential component of almost all machinery. They transmit loads between, support, guide and locate, machine elements that are required to move relative to each other with a minimum of friction, e.g.a rotating or oscillating shaft, pivot or wheel.Friction: Page 1Friction counteracts the movement between two surfaces. It is essential for the success of many operations, such as a car tyre gripping a road. In most machines however, friction is undesirable since it causes power loss, heat generation, wear and noise. SKF bearings help reduce friction.Friction: Page 2The earliest bearings were mostly made of wood and consisted of a shaft rotating in a hole in a housing, or a wheel rotating on a stationary shaft. Because the components were sliding over each other, friction was relatively high and wear rather rapid.This type of bearing is called a plain bearing and, made of modern materials, is still used in some applications today where speeds and loads are relatively low.Friction: Page 3The introduction of rolling elements between the shaft and the housing greatly reduces friction.Friction: Page 4Today, typical SKF rolling bearings combine maximum load capacity with minimum friction, using hardened steel or ceramic rolling elements, hardened steel inner and outer rings and a cage to guide and separate the rolling elements.Loads: Page 1A bearing can be under radial load, perpendicular to the shaft, or under axial load, acting in the direction along the shaft, or a combination of both radial and axial load, a combined load.Loads: Page 2Large bearings support heavier loads than small bearings can support, and roller bearings support heavier loads than ball bearings can support. Raceway contactThe basic difference between ball bearings and roller bearings is in the contacts between the rolling elements and the raceways. Balls have point contact; rollers have linear contact with relatively larger area.Bearing partsA typical rolling bearing consists of an inner ring, an outer ring and rolling elements contained by a cage. The most common type of rolling bearing is the deep groove ball bearing. These bearings can, as shown here, be supplied with integral seals to retain the lubricant and resist the ingress of contamination.Selection factorsThere are many factors, which will affect the choice of a bearing. These are: Available space, load, required service life, misalignment, speed, stiffness, axial displacement and clearance.Selection factors: SpaceSpace can be an important factor in bearing selection. Where radial space is limited a bearing with small diameter rolling elements, such as a needle roller bearing, may be needed.Selection factors: LoadWhen selecting a bearing, it is important to consider the direction of the load, and the amount of load the bearing will have to carry. A bearing can be under radial load, axial load, or a combination of both.Selection factors: Required service lifeThe life of a bearing can be expressed in terms of: the number of revolutions before failure, the number of operating hours before failure, or the distance covered (for cars and trucks). A bearing is considered to have failed when it shows the first sign of fatigue in a rolling element or raceway, or damage to other parts such as the cage or the seals. Service life is the real life that an individual bearing achieves in a particular application before it has to be replaced. It depends on a variety of influencing factors, including lubrication, the degree of contamination, misalignment, proper installation, and environmental conditions.Because service life cannot be calculated or predicted, bearings are selected using calculated rating life. SKF rating life L10m, a reference value calculated according to statistical methods, using modification factors for lubrication conditions and degree of contamination, and applying the same concept of a fatigue load limit as used in ISO 281, to estimate the life, with 90% reliability, that a sufficiently large population of apparently identical bearings might achieve when all are operating in an identical application.Selection factors: MisalignmentWhere a bearing is likely to be subject to angular misalignment, for example the shaft might bend due to operating loads, appropriate bearings need to be selected. Self-aligning bearings can accept a degree of operational misalignment and can also compensate for limited initial alignment errors in mounting.Selection factors: SpeedThe maximum speed that a bearing can be run in an application is limited by the maximum operating temperature for the materials used in its manufacture, or the lubricant. For high-speed applications minimum possible friction is important, so ball bearings are generally used. Selection factors: StiffnessElastic deformation occurs under load. Usually this deformation is very small and can be ignored. However, in some applications, stiffness is an important factor. Roller bearings have higher stiffness than ball bearings due to the larger area of the line contact.Selection factors: Axial displacementSome applications require bearings that allow the shaft to move axially relative to the bearing. This is called axial displacement. Most often, a shaft is supported by a locating bearing and a non-locating bearing. The locating bearing does not allow axial displacement and keeps the shaft in position. The non-locating bearing supports the shaft and allows displacement to prevent the bearings from being stressed. Cylindrical and CARB toroidalroller bearings can accommodate a limited degree of axial internal displacement.Selection factors: ClearanceThe amount of initial internal radial clearance required in a bearing depends mainly on the fits and temperature gradient between the inner and outer rings of the bearing in the particular application. Operational internal radial clearance is almost always less than initial internal clearance. SKF manufactures bearings with the following ranges of radial internal clearances:•C1 radial internal clearance less than C2•C2 radial internal clearance less than Normal•-- Normal radial internal clearance•C3 radial internal clearance greater than Normal•C4 radial internal clearance greater than C3SummaryIn this lesson, you have learnt about the functions of a bearing. These are: reducing friction, transmitting loads, locating and guiding moving parts. You have also been introduced to the different parts of a bearing: outer and inner rings, rolling elements, cage, and seals and their respective functionalities.Finally, you have also explored the different selection factors, which will affect your choice of bearing: available space, load, required service life, misalignment, speed, stiffness, axial displacement and clearance.Module 2: ApplicationsIntroductionIn this section you will be introduced to the most common bearing types offered by SKF.Electrical motors can be found almost anywhere there is mechanical movement.Motor: Page 2In this drawing you can see that the shaft is supported by two different bearings.Motor: Page 3Cylindrical roller bearings are simply bearings with cylindrical rollers. They can usually accommodate heavy radial loads and can operate at relatively high speeds.Motor: Page 4It is now time to choose the right side bearing.Motor: Page 5Deep groove ball bearings have deep uninterrupted raceways and close osculation between balls and raceways. This enables them to take axial loads in both directions.Pump: Page 1A pump is a device for lifting, transferring or moving fluids by suction or pressure from one position to another. This picture shows a medium-duty process pump, which is often used in refineries.Pump: Page 2In this drawing you can see that the shaft, which is running the impeller, is supported by one deep groove ball bearing to the right, and another bearing or bearings to the left.Single row angular contact ball bearings are widely used in medium and heavy-duty centrifugal pumps. They have raceways arranged at an angle to the bearing axis.Pump: Page 4Single row angular contact ball bearings can only take axial load in one direction. Therefore they are nearly always mounted as pairs in back to back or face to face arrangement at either end of a shaft, or as shown here, universally matchable bearings mounted immediately adjacent to each other.Fan: Page 1This is an industrial fan, in which SKF bearings are commonly used. Industrial fans can either be designed for light loads and high speeds, or for heavy loads and moderate speeds.Fan: Page2A fan is designed with two bearings along its shaft, placed between the fan and the motor. Both bearings carry radial loads and the bearing closest to the fan (on the left hand side here) also needs to be a locating bearing, keeping the shaft and the fan in a fixed position.Fan: Page 3Spherical roller bearings have two rows of rollers with a common raceway in the outer ring. The two inner ring raceways are inclined at an angle to the bearing axis.Fan: Page 4Returning to the fan application again, you now know which bearing is suitable as the locating bearing and here you have to make a guess concerning the non-locating bearing.CARB [ka:b] is a single row toroidal roller bearing with long, slightly crowned, rollers and concave raceways in both the inner and outer rings. Fan: Page 6The complete application looks like this with one spherical roller bearing and one CARB toroidal roller bearing.Separator: Page 1Alfa Laval, a Swedish company, has developed a range of machines specifically designed for rigorous oil processing duties. An example of this would be separators.Separator: Page 2The separation process creates imbalance due to the mud, which is distributed unevenly inside the separator and this makes the spindle bend. Separator: Page 3Self-aligning ball bearings have two rows of balls and a common concave sphered raceway in the outer ring. This makes the bearing insensitive to angular misalignments of the shaft relative to the housing. Self-aligning ball bearings accommodate high speeds due to the point contact between balls and raceways.Refiner: Page 1SKF bearings can be used in refiners in the production of mechanical pulp and other high-yield pulps.Refiner: Page 2In the process wood chips are ground at high mechanical pressure between a stationary disc and a rotating disc, which is powered by an electrical motor. The shaft between the motor and the grinding discs is supported by three bearings.Refiner: Page 3The high production capacity of the refiners is directly related to the demands on the bearing arrangement. The bearings have to provide high stability, operate at high speed, carry high thrust loads and handle deflections of the shaft.Refiner: Page 4The spherical roller thrust bearing incorporates a large number of asymmetrical, spherical rollers and has specially designed raceways. The load is transmitted from one raceway to the other at an angle to the bearing axis and the bearing can carry heavy axial load in one direction and some simultaneously applied radial load as well.Refiner: Page 5This is how the spherical roller thrust bearings are situated in the refiner application.Screw conveyor: Page 1Machines used in the agricultural industry often require bearings that can easily be changed and that can handle misalignments.Screw conveyor: Page 2This is a drawing of a screw conveyor attached to an agricultural machine. The bearings are the only contact between the screw conveyor and the machine.Screw conveyor: Page 3A Y-bearing unit consists of two parts: a housing and a bearing. The bearing is based on the deep groove ball bearing and can carry light radial and axial loads. It has a convex-sphered outside diameter, which allows the bearing to take up misalignment between the shaft and housing at the assembly stage. They are available with a wide range of highly effective,integral seals and a range of different methods for easy mounting to the shaft.Screw conveyor: Page 4This is what the Y-bearing unit looks like in the screw conveyor.Front wheel: Page 1SKF bearings are used in front wheels of commercial vehicles. These applications require bearings that can handle very heavy loads.Front wheel: Page 2This drawing shows how a truck front wheel arrangement is designed and where its bearings are situated. The bearings must carry a large part of the weight of the vehicle and the induced forces when driving, which means that they have to handle heavy loads in both radial and axial directions.Front wheel: Page 3Tapered roller bearings have tapered rollers running in tapered inner and outer ring raceways. This design makes them suitable for handling heavy combined loads.A tapered roller bearing can only carry axial loads in one direction and, for this reason, they are generally fitted in pairs.Front wheel: Page 4See how the tapered roller bearings are mounted in the front wheel of a commercial vehicle.SummaryIn this lesson, you have studied the most common SKF bearing types. Now click on each bearing picture to repeat the most important characteristics of each type. If you want to read more about SKF bearings, enter the SKF Interactive Engineering Catalogue on line at .Module 3: DesignationsIntroductionSKF bearing designations describe a bearing’s or component’s type, design, and variants. The designation can be found both on the box and on the bearing itself.Basic designations: Page 1A bearing designation for metric size bearings can either consist of a basic designation alone or a basic designation plus one or more supplementary designations, called prefixes and suffixes.The basic designation identifies the product type and size, while the supplementary designations identify design, special variants and bearing components.Basic designations: Page 2Each SKF bearing of standard metric design is given a basic designation, which normally consists of three, four or five figures.Basic designations: Page 3For example, the basic designation 22206 denotes a spherical roller bearing with the width series 2, diameter series 2 and a bore diameter of 30 mm.Supplementary designations: Page 1The supplementary designations consist of both prefixes and suffixes. Supplementary designations: Page 2Prefixes are used to identify component parts of a bearing and are usually followed by the designation of the complete bearing.Supplementary designations: Page 3Suffixes are used to identify designs, which differ in some way from the original design. The suffixes are divided into four main groups: Internal design, external design, cage design and variants, all of which are added to the basic designation in this order.End of course testNow it’s time to see what you learned.If you pass the test on-line then you’ll be able to print your course completion certificate.。

They are simple in de-sign, non-separable, suitable for high and even very high speeds and are robust in operation, requiring little maintenance. Deep raceway grooves and the close conformity between the raceway grooves and the balls enable deep groove ball bearings to accom-modate axial loads in both directions, in addition to radial loads, even at high speeds. Single row deep groove ball bearings are the most widely used bearing type. Conse-quently, they are available from SKF in many executions and sizes:•open basic design bearings•sealed bearings•ICOS TM oil sealed bearing units •bearings with snap ring groove, with or without snap ringOther deep groove ball bearings for special applications, shown in the sections “Engineering products” and “Mechatronics”include•hybrid bearings ( page 891)•insulated bearings ( page 905)•high temperature bearings ( page 917)•bearings with Solid Oil ( page 945)•sensorized bearings ( page 953)The SKF product range also includes inch-size bearings and bearings with a tapered bore. These variants are not included in this General Catalogue. Information will be provided on request.Single row deep groove ball bearings290DesignsBasic design bearingsBasic design SKF single row deep groove ball bearings ( fig) are open (unsealed). For manufacturing reasons, those sizes of open bearing that are also produced in sealed or shielded versions may have seal recesses in the outer ring.Sealed bearingsThe most popular sizes of deep groove ball bearings are also produced in sealed versions with shields or contact seals on one or both sides. Details regarding the suitability of the different seals for various operating condi-tions will be found in table. Sealed bear-ings in the wide 622, 623 and 630 series are particularly suitable for long maintenance-free service. In addition, ICOS bearing units with integrated radial shaft seals are avail-able for higher sealing requirements.The bearings with shields or seals on both sides are lubricated for life and are mainten-ance-free. They should not be washed or heated to temperatures above 80 °C. Depend-ing on the series and size, deep groove ball bearings are supplied charged with one of three standard greases:•LT10 grease for bearings in the 8 and9 Diameter Series up to and including30 mm outside diameter,11•MT47 grease for bearings in the 8 and 9Diameter Series above 30 mm up to andincluding 62 mm outside diameter and forbearings in the 0, 1, 2 and 3 DiameterSeries up to and including 62 mm outsidediameter,•MT33 grease for all bearings above 62 mmoutside diameter.Characteristics of the above standardgreases are listed in table . The standardgrease is not identified in the bearing desig-nation. The quantity of grease fills some 25to 35 % of the free space in the bearing. Tospecial order, other grease filling grades areavailable. Also on request, special greasefills ( table ) can be supplied 22•high temperature grease GJN for bearings up to and including 62 mm outside diameter •high temperature grease HT22 for bearings above 62 mm outside diameter •low temperature grease LT20 •wide temperature range grease GWB •wide temperature range and silent running grease LHT23291Single row deep groove ball bearings 292Bearings with shieldsBearings with shields, designation suffix Zor 2Z, are produced in one of two designs,depending on the bearing series and size( fig ). The shields are made of sheetsteel and normally have a cylindrical exten-sion in the shield bore to form a long sealinggap with the inner ring shoulder (a ). Someshields do not have the extension (b ).Shielded bearings are primarily intendedfor applications where the inner ring rotates.If the outer ring rotates, there is a risk thatthe grease will leak from the bearing at highspeeds.Bearings with low-friction sealsSKF deep groove ball bearings with low-friction seals, designation suffixes RSL,2RSL or RZ, 2RZ, are manufactured in threedesigns depending on bearing series andsize ( fig ):•bearings in the 60, 62 and 63 series up to25 mm outside diameter are equipped withRSL seals to design (a ),•bearings in the 60, 62 and 63 series from25 mm and up to and including 52 mmoutside diameter are equipped with RSLseals to design (b ),•other bearings have RZ seals (c ).The seals form an extremely narrow gapwith the cylindrical surface of the inner ring32shoulder or recess profile and are practically non-contacting. Because of this, bearings fitted with low-friction seals can be operated at the same high speeds as bearings with Z shields, but with improved seal performance.The low-friction seals are made of oil and wear-resistant acrylonitrile butadiene rubber (NBR) with a sheet steel reinforcement. The permissible operating temperature range for these seals is −40 to +100 °C and up to +120 °C for brief periods.Bearings with contact seals Bearings with contact seals, designation suffixes RSH, 2RSH or RS1, 2RS1, are manu-factured in four designs depending on bear-ing series and size ( fig ):•bearings in the 60, 62, and 63 series up to 25 mm outside diameter are equipped with RSH seals to design (a ),•bearings in the 60, 62 and 63 series from 25 mm and up to and including 52 mm outside diameter are equipped with RSH seals to design (b ),•other bearings have RS1 seals, which seal against the cylindrical surface of the inner ring shoulder (c ) indicated by dimension d 1in the product table or against a recess in the inner ring side face (d ) indicated by dimension d 2in the product table. The seals are inserted in recesses in the outer ring and provide good sealing at this4position without deforming the outer ring.Standard seals are made of acrylonitrilebutadiene rubber (NBR) with a sheet steelreinforcement. The permissible operatingtemperature range for these seals is −40 to+100 °C and up to +120 °C for brief periods.When sealed bearings are operated undercertain extreme conditions, e.g. very highspeeds or high temperatures, grease leak-age may occur at the inner ring. For bearingarrangements where this would be detrimen-tal, special design steps must be undertaken,please consult the SKF application engin-eering service.ICOS TM oil sealed bearing unitsICOS oil sealed bearing units have beendeveloped by SKF . The new concept aimsat applications where sealing requirementsexceed the capabilities of standard sealedbearings. An ICOS unit consists of a 62 series deep groove ball bearing and anintegral CR radial shaft seal ( fig ). Theseunits need less space than common two-component arrangements; they simplifymounting, and avoid expensive machiningof the shaft because the inner ring shoulderserves as a perfect seal counterface.The CR radial shaft seal is made of acrylo-nitrile butadiene rubber (NBR) and has a spring loaded Waveseal lip. The permissibleoperating temperature range for the seal is−40 to +100 °C and up to +120 °C for briefperiods.5The speed limits quoted in the product table are based on the permissible circum-ferential speed for the CR seal, which in this case is 14 m/s.293Bearings with snap ring grooveDeep groove ball bearings with a snap ringgroove can simplify arrangement design as the bearings can be axially located in thehousing by a snap (or retaining) ring ( fig ).This saves space. Appropriate snap rings areshown in the product table with designationand dimensions and may be supplied sep-arately or already mounted on the bearing.SKF deep groove ball bearings with asnap ring groove ( fig ) are supplied as:•open (unsealed) bearings, designationsuffix N (a );•open bearings with a snap ring, designa-tion suffix NR (b );•bearings with a Z shield at the oppositeside and a snap ring, designation suffixZNR (c );•bearings with Z shields on both sides anda snap ring, designation suffix 2ZNR (d ).Matched bearing pairsFor bearing arrangements where the loadcarrying capacity of a single bearing is inad-equate, or where the shaft has to be axiallylocated in both directions with a given amountof axial clearance, SKF can supply matchedpairs of single row deep groove ball bearingsto order.Depending on the requirements thematched pairs can be supplied in tandem,back-to-back, or face-to-face arrangements( fig ).The bearings are matched in pro-duction so that, when mounted immediatelyadjacent to each other, the load will be even-876Single row deep groove ball bearings294ly distributed between the bearings without having to use shims or similar devices. Further information on matched bearing pairs can be found in the “SKF Interactive Engineering Catalogue” on CD-ROM or online at .SKF Explorer class bearingsHigh performance SKF Explorer deep groove ball bearings are shown with an asterisk in the product tables. The higher performance of SKF Explorer deep groove ball bearings also includes quieter running. SKF Explorer bearings retain the designation of the earlier standard bearings. However, each bearing and its box are marked with the name “EXPLORER”.295Bearing data – generalDimensionsThe boundary dimensions of SKF single row deep groove ball bearings are in accordance with ISO 15:1998. Dimensions of the snap ring grooves and snap rings comply with ISO 464:1995.TolerancesSKF single row deep groove ball bearings are manufactured as standard to Normal tolerances.SKF Explorer single row deep groove ball bearings are produced to higher precision than the ISO Normal tolerances. The dimen-sional accuracy corresponds to P6 toler-ances, except the width tolerance, which is considerably tighter and reduced to •0/−60 µm for bearings with outside dia-meter up to 110 mm and•0/−100 µm for larger bearings.The running accuracy depends on the bear-ing size and corresponds to•P5 tolerances for bearings up to 52 mm outside diameter,•P6 tolerances for bearings above 52 mm up to 110 mm outside diameter and •Normal tolerances for larger bearings.For bearing arrangements where accuracy is a key operational factor some SKF single row deep groove ball bearings are also avail-able with accuracy completely to P6 or P5tolerance class specifications. The availabil-ity of these bearings should always be checked before ordering.The tolerances are in accordance with ISO 492:2002 and can be found in tables to , starting on page 125.Internal clearanceSKF single row deep groove ball bearings are manufactured with Normal radial internal clearance as standard. Most of the bearings are also available with C3 radial internal clearance. Some of the bearings can even be supplied with the appreciably greater C4or the smaller C2 clearances. In addition,deep groove ball bearings are available with 53reduced or displaced internal clearance ranges. These special clearances may use reduced ranges of standard clearance classes or partitions of adjacent classes ( designation suffix CN on page 300).Bearings with internal clearance not to standard are supplied on request.The values for radial internal clearance are given in table . They are in accordance with ISO 5753:1991 and are valid for unmounted bearings under zero measuring load.MisalignmentSingle row deep groove ball bearings have only limited ability to accommodate misalign-ment. The permissible angular misalignment between the inner and outer rings, which will not produce inadmissibly high additional stresses in the bearing, depends on •the radial internal clearance of the bearing in operation, •the bearing size,•the internal design and•the forces and moments acting on the bearing.Because of the complex relationship between these factors, no generally applicable spe-cific values can be given. However, depend-ing on the various influences of the factors,the permissible angular misalignment lies between 2 and 10 minutes of arc. Any mis-alignment will result in increased bearing noise and reduced bearing service life.3Single row deep groove ball bearings296297Single row deep groove ball bearings298CagesDepending on the bearing series and size, SKF single row deep groove ball bearings are supplied with one of the following cages ( fig ):•ribbon-type cage of steel or brass sheet (a )•riveted cage of steel or brass sheet (b )•machined brass cage (c )•snap-type cage of polyamide 6,6 (d )Bearings having a pressed steel cage in standard execution may also be available with a machined brass or polyamide cage.For higher operating temperatures, poly-amide 4,6 or PEEK cages may be advanta-geous. Before ordering, please check for availability.Note:Deep groove ball bearings with polyamide 6,6 cages can be operated at temperatures up to +120 °C. The lubricants generally used for rolling bearings do not have a detrimental effect on cage properties, with the exception of a few synthetic oils and greases with a synthetic oil base and lubricants containing a high proportion of EP additives when used at high temperatures.For bearing arrangements, which are to be operated at continuously high temperatures or under arduous conditions, SKF recom-mends using bearings with a pressed steel or a machined brass cage.9For detailed information regarding the temperature resistance and the applicability of cages, please refer to the section “Cage materials”, starting on page 140.Minimum loadIn order to provide satisfactory operation,deep groove ball bearings, like all ball and roller bearings, must always be subjected to a given minimum load, particularly if they are to operate at high speeds or are subjected to high accelerations or rapid changes in the direction of load. Under such conditions the inertia forces of the balls and cage, and the friction in the lubricant, can have a detrimental effect on the rolling conditions in the bearing arrangement and may cause damaging slid-ing movements to occur between the balls and raceways.The requisite minimum radial load to be applied to deep groove ball bearings can be estimated using νn d m F rm = k r()2/3()21 000100whereF rm = minimum radial load, kN k r = minimum load factor( product tables)ν= oil viscosity at operatingtemperature, mm 2/s n = rotational speed, r/min d m = bearing mean diameter= 0,5 (d + D), mmWhen starting up at low temperatures or when the lubricant is highly viscous, even greater minimum loads may be required. The weight of the components supported by the bearing, together with external forces, generally exceeds the requisite minimum load. If this is not the case, the deep groove ball bearing must be subjected to an addi-tional radial load. For applications where deep groove ball bearings are used, an axial preload can be applied by adjusting the inner and outer rings against each other, or by using springs.Axial load carrying capacityIf deep groove ball bearings are subjected to purely axial load, this axial load should generally not exceed the value of 0,5 C0. Small bearings (bore diameter up to approx.12 mm) and light series bearings (Diameter Series 8, 9, 0, and 1) should not be subject-ed to an axial load greater than 0,25 C0. Excessive axial loads can lead to a consid-erable reduction in bearing service life. Equivalent dynamic bearing loadFor dynamically loaded single row deep groove ball bearingsP = F r when F a/F r≤eP = XF r+YF a when F a/F r> eThe factors e, X and Y depend on the rela-tionship f0F a/C0, where f0is a calculation factor ( product tables), F a the axial com-ponent of the load and C0the basic static load rating.In addition, the factors are influenced by the magnitude of the radial internal clearance; increased clearance allows heavier axial loads to be supported. For bearings mounted with the usual fits (shaft tolerance j5 to n6 depend-ing on the shaft diameter, and housing bore tolerance J7), the values for e, X and Y are listed in table. If a clearance greater than Normal is chosen because a reduction in clearance is expected in operation, the values given under “Normal clearance” should be used.Equivalent static bearing loadFor statically loaded single row deep groove ball bearingsP0= 0,6 F r+0,5 F aIf P0< F r, P0= F r should be used.4299Supplementary designationsThe designation suffixes used to identity certain features of SKF deep groove ball bearings are explained in the following.CN Normal radial clearance; generally only used in combination with one ofthe following letters that indicate re-duced or displaced

Handle with care. Never pound directly on a bearing or ring. If a bearing is dropped, it is best not to install it. Store bearings horizontally in a dry place in their original unopened package and never place bearings on a dirty surface; periodically turn over sealed and shielded bearings to prevent grease from settling to one side.2. Inspect the shaft and housing. Check for size and damage; remove nicks and burrs with emery paper, and wipe clean with a soft cloth. Replace or repair shafts and housings showing obvious signs of wear or damage. A shaft placed in a vise for mounting should be protected from vise jaws with a sheet of soft metal.3. Avoid overheating. During heat-mounting operations, never bring a flame in direct contact with the bearing and never heat beyond 230° F. Also, immediately hold a heat-mounted bearing in place against the shaft shoulder until it cools and locks in place. Otherwise, the bearing may creep away from the proper position.4. Use identical replacement bearings. Replacement bearings should be identical to the bearings they replace. Contact an SKF Authorized Distributor or SKF for interchange information.5. Use the right tool for the job. Induction heaters, oil injection kits, and hydraulic nuts are among the specialized tools available for mounting and dismounting bearings over 4 in. O.D. Their use lowers the possibility of damaging bearings and speeds the process.6. Pay attention to the bearing’s press fit. For bearings with an O.D. less than 4 inches, cold mounting with a press or appropriate mounting tool is acceptable. Pressure should be applied to the ring with the inter-ference fit, or both the inner ring and outer ring simultaneously to avoid Brinelling the raceways. Applying pressure to the ring with the loose fit only will Brinell the raceways and result in noise and potentially premature failure.Installation tips forreliable bearing operation7. The contact between the bearing ring and a properly machined and dimensioned bearing seat should not require the use of bonding agents to prevent movement or turning.8. Don’t wash new bearings. Bearing manufacturers take great care to package and ship bearings that are dirt-free and ready for lubrication. There’s usually no need to wash them or remove the protective slushing compound.9. Proper lubrication is critical. Bearing manufacturers evaluate several factors before determining the type of lubricant required for specific bearings. Be sure to follow their recommendations. Temperature and contamination conditions will influence the frequency of lubrication changes.10. Rotate idle bearings. Bearings installed in equipment that is subject to vibration while the shafts are stationary may incur false brinel-ling damage, which also occurs when equipment is not properly protected during shipment. It can appear as bright, polished depressions on the inner and/or outer races, as well as on the rolling elements.11. Look for danger signs. Keep alert for three sure signs of improper bearing operation: excessive noise and increases in vibration and tem-perature. Troubleshooting instruments like hand-held vibration pens, digital thermometers, and electronic stethoscopes help spot bearingsin poor operating conditions.12. Find the cause of bearing failures. Bearings are built to last, so frequent failures may point to an installation or lubrication problem. SKF bearing analysis experts can identify the cause of bearing failure and help you prevent it in the future.3Speed ratingsThere is a speed limit to which rolling bearings can be operated. Generally, it is the operating temperature that can be permitted with respect to the lubricant being used or to the material of the bearing components that sets the limit. The speed at which this limiting bearing temperature is reached depends on the frictional heat generated in the bearing (including any exter-nally applied heat) and the amount of heat that can be transported away from the bearing. Bearing type and size, internal design, load, lubrication and cooling conditions as well as cage design, accuracy and internal clearance all play a part in determining speed capability. In the accompanying tables two speeds are listed: (Thermal) Reference Speed and (Kinematic) Limiting Speed. Warning: The new Reference and Limiting Speeds are not to be used as a direct substitution for the previous Oil and Grease speed ratings. Consult SKF to determine the actual reference speed limit for your operating conditions. Reference speedsThe reference speed for a given bearing represents the permissible operating speed of said bearing when subjected to the specific operating conditions of load, lubrication type and method as outlined in ISO 15312. This standard has been established for oil lubrication but is also valid for grease and uses the following reference conditions:• A temperature increase of 90° F (50° C) above an ambient temperature of 68° F (20° C), (thus a bearing temperature of 158° F (70° C), measured on the bearing stationary outer ring or housing washer.• R adial bearing: a constant radial load, being 5% of the basic static load rating C o.•T hrust bearing: a constant axial load, being 2% of the basic static load rating C o.• O pen bearings with Normal clearance.For oil lubricated bearings:• L ubricant: mineral oil without EP-additives having a kinematic viscosity at 158° F (70° C) of: v = 12 mm2/s (ISO VG32) for radial bearings, and v = 24 mm2/s (ISO VG68) for thrust roller bearings• O il bath with the oil reaching up to the middle of the rolling elementin the lowest position.For grease lubricated bearings:• R egular lithium soap grease with mineral base oil having a viscosityof 100 to 200 mm2/s at 104° F (40° C) (e.g. ISO VG 150).• F illing approximately 30% of the free space in the bearing.The reference temperature will be reached after 10 to 20 hours running time. Under these specific conditions the reference speed for oil and grease lubrication will be equal.4Speeds above the reference speedIt is possible to operate bearings at speeds above the reference speed if the friction within the bearing can be reduced, for example by lubrication systems with small, accurately measured quantities of lubricant or when heat can be removed from the bearing by circulating oil lubrication with cooling of the oil, by cooling ribs on the housing, or by directed cooling air streams.Any increase in speed above the reference speed without taking any of these precautions would only cause bearing temperature to rise exces-sively. An increase of bearing temperature means that lubricant viscosity is lowered and film formation is made more difficult, leading to even higher friction and further temperature increases. If, at the same time, the operational clearance in the bearing is reduced because of increased inner ring temperature, the final consequence would be bearing seizure. Limiting speedsThe speed limit is determined by criteria that include: the stability and or strength of the cage, lubrication of cage guiding surfaces, centrifugal and gyratory forces acting on the rolling elements, and other speed-limiting factors. Experience gained from laboratory tests and practical applications indicates that there are maximum speeds that should not be exceeded for technical reasons or because of the very high costs involved.Limiting Speeds shown in the tables are based on the demands of high speed running applications and are valid only for the specific design and cage design shown in the tables. It is possible to run bearings faster than the limiting speeds, but several factors must be reviewed and improved such as the running accuracy, cage material, lubrication, heat dissipa-tion and design of the bearing. It is therefore advisable to contact SKF Applications Engineering for advice. For enclosed and open bearings using grease lubrication, additional parameters have to be considered such as lubrication of cage guiding surfaces and the shear strength of the lubri-cant, which is determined by the base oil and thickener.Open ball bearings with low friction typically have Reference Speeds greater than the Limiting Speed.

Lubricate more often in applications where there is a risk of heavy solid and chemical contamination. Consult manufacturer or SKF Application Engineering for details.LGHP 2 ball and roller bearing greaseLGHP 2 is a polyurea-based grease designed for use in electric motors. Unlike many polyurea-based greases, which are inherently noisy during operation, LGHP 2 meets strict SKF noise requirements. Each batch is blend-ed and selected for consistency and adherence to quietness standards. The grease is also recommended for applications where long life is required.With LGHP 2, users can often avoid compatibility problems when relu-bricating bearings. LGHP 2 is the factory fill grease used in SKF bearings 62000.04 oz.25,900 hr 23,400 hr 19,100 hr 62010.07 oz.25,60022,90018,40062020.07 oz.25,20022,20017,30062030.07 oz.24,80021,50016,10062040.10 oz.24,20020,40014,50062050.12 oz.23,60019,40013,10062060.15 oz.22,70018,00011,30062070.19 oz.21,90016,7009,70062080.23 oz.21,10015,6008,51062090.25 oz.20,60014,8007,69062100.28 oz.20,10014,1006,95062110.33 oz 19,40013,1005,97062120.38 oz.18,60012,1005,13062130.43 oz.17,90011,2004,41062140.47 oz.17,50010,7003,98062150.50 oz.17,10010,2003,60062160.55 oz.16,4009,4003,09062170.65 oz.15,8008,7302,66062180.74 oz.15,2008,0902,28062190.84 oz.14,7007,5001,96062200.95 oz.14,1006,95063000.07 oz.25,600 hr 22,800 hr 18,200 hr 63010.07 oz.25,30022,400 17,40063020.11 oz.24,80021,50016,10063030.11 oz.24,40020,70015,00063040.12 oz.23,90019,90013,80063050.16 oz.23,00018,40011,90063060.21 oz.22,10017,10010,20063070.26 oz.21,40016,0008,95063080.32 oz.20,60014,8007,69063090.39 oz.19,90013,8006,61063100.46 oz.19,10012,8005,68063110.54 oz.18,40011,8004,88063120.63 oz.17,70011,0004,19063130.72 oz.17,10010,2003,60063140.81 oz.16,4009,4103,09063150.92 oz.15,8008,7302,6606316 1.03 oz.15,2008,0902,2806317 1.14 oz.14,7007,5001,9606318 1.26 oz.14,1006,9506319 1.40 oz.13,6006,4406320 1.57 oz.12,9005,820Grease relube recommendation Deep groove ball bearings 6300 seriesBearing quantity interval @ 900 rpm 1800 rpm 3600 rpmNote: The relubrication intervals shown are based on a good quality lithium based grease at a maximum temperature of 160° F, and a c /p =15.

The seals are suitable for operation up to 392°F (200°C). Afluroelestomer base will resist ignition under any conditions outside special furnace condition, but if exposure to heat (due to fire or any other conditions) is extreme, e.g.over 572°F (300°C) for more than a brief time, degradation will occur. Fluoro rubber emits dangerous fumes at temperatures of 572°F (300°C) and above. This may occur if the seals are subjected to extreme heat during dismounting, for example. Once ithas been overheated, fluoro rubber will remain dangerous to handle even when it has cooled down. This degraded product is a major health and safety danger due to the evolution of hydrofluoric acid (HF). It is necessary to handle overheated fluoro rubber seals carefully; always observe safety instructions and wear goggles and protective gloves. Under no circumstances should material (hot or cold) be allowed to contact skin. If hands or eyes have come into contact with the material or fumes, they should be washed or rinsed in plenty of water. A doctor should always be consulted especially if the fumes have been inhaled.Decontamination can be carried out using limewater (calcium hydroxide solution); use of P .V.C. gloves is essential. Afterneutralization, the degraded seal can be disposed of in a similar manner to an un-degraded one.The user is responsible for the correct handling of the seals during bearing life,and for the proper disposal of used seals.Seals of fluoro rubber and bearingsincorporating them are not dangerous to handle provided they have never been overheated.Spherical roller bearingsMounting InformationPlease go

161ECB 22240 CCK JA/ C3 W3312345Spherical Roller Bearings6162Boundary Dimensions in accordance with ISO 15:1998TolerancesSKF spherical roller bearings are manufactured as stan-dard to normal tolerances. SKF Explorer bearings up to 315 mm bore diameter are produced to higher precision than the ISO normal tolerances. The width tolerance is considerably tighter*. The running accuracy is to tolerance class P5 as standard.For larger bearings P5 tolerances are also available with the suffix C08 or closer tolerances are available with suffix VQ424.Vibratory bearings are manufactured to; bore P5 and O/D P6.

The seals are suitable for operation up to 392°F (200°C). Afluroelestomer base will resist ignition under any conditions outside special furnace condition, but if exposure to heat (due to fire or any other conditions) is extreme, e.g.over 572°F (300°C) for more than a brief time, degradation will occur. Fluoro rubber emits dangerous fumes at temperatures of 572°F (300°C) and above. This may occur if the seals are subjected to extreme heat during dismounting, for example. Once ithas been overheated, fluoro rubber will remain dangerous to handle even when it has cooled down. This degraded product is a major health and safety danger due to the evolution of hydrofluoric acid (HF). It is necessary to handle overheated fluoro rubber seals carefully; always observe safety instructions and wear goggles and protective gloves. Under no circumstances should material (hot or cold) be allowed to contact skin. If hands or eyes have come into contact with the material or fumes, they should be washed or rinsed in plenty of water. A doctor should always be consulted especially if the fumes have been inhaled.Decontamination can be carried out using limewater (calcium hydroxide solution); use of P .V.C. gloves is essential. Afterneutralization, the degraded seal can be disposed of in a similar manner to an un-degraded one.The user is responsible for the correct handling of the seals during bearing life,and for the proper disposal of used seals.Seals of fluoro rubber and bearingsincorporating them are not dangerous to handle provided they have never been overheated.Spherical roller bearingsMounting InformationPlease go
