To overcome this problem the end faces of the mounting bolt seat are secured with stoppers to lock the plummer block. With the plummer block used in this type of application, the end faces in contact with the stoppers are machined.When a plummer block mounting seat end faces have been machined, the bottom length L of the bearing housing is smaller by the dimension in Table 2.5.Table 2.5 Machining allowanceTable 2.6 Tolerances of dimension L after machining ofmounting bolt seat end facesL : Basic casting dimension (as cast dimension)L ': Dimension after machining of the end faces of bearing basePlummer Block and Rolling Bearing Tolerances2.3 Rolling bearing accuraciesThe tolerances of self-aligning ball and roller bearingsused in conjunction with NTN plummer blocks conform toJIS B 1514 (Tolerances for rolling bearings).Table 2.7 Bearing tolerances(1) Tolerances of inner rings (JIS class 0)(2) Tolerances of outer rings (JIS class 0)Plummer Block and Rolling Bearing Tolerances(3) Tolerance and allowable values (JIS class 0) of tapered 1 bore radial bearings 1 Applicable to all radial planes of tapered bore Note 1: Applicable to 1/12 tapered bore2: Quantifiersd 1: Standard diameter at theoretical large end of tapered bore∆d mp : Single plane mean bore diameter deviation attheoretical small end of tapered bore∆d 1mP : Single plane mean bore diameter deviation attheoretical large end of tapered boreV dp : Bore diameter variation in a single radial plane B : Nominal bore diameter: 1/2 nominal taper angle of tapered bore = 2˚23'9.4'' = 2.38594˚ = 0.041643 radd 1 = d B121Theoretical tapered boreTapered bore associated with single plane mean bore diameter deviationPlummer Block and Rolling Bearing Tolerances2.4 Rolling bearing internal clearanceThe radial clearance values of the self-aligning ball bearings used in the NTN plummer blocks aresummarized in Table 2.8 (1) and (2), and those of the self-aligning roller bearings in Table 2.9 (1) and (2).(1) Data for cylindrical bore bearingsTable 2.8 Radial internal clearance of self-aligning ball bearings (2) Data for tapered bore bearingsPlummer Block and Rolling Bearing TolerancesTable 2.9 Radial internal clearance of self-aligning roller bearings(1) Data for cylindrical bore bearings(2) Data for tapered bore bearingPlummer Block and Bearing Materials 3. Plummer Block and Bearing Materials3.1 Plummer block materialsThe housings of NTN plummer blocks are made of class 3gray cast iron (FC200). Table 3.1summarizes themechanical properties of this material.Cast iron materials boasts the greatest vibrationdampening capability among various metal materials.They also perform well in a wider operating temperaturerange of –20 to 300˚C.For application involving shock load and vibration, class 2spheroidal graphite cast iron (FCD450) or class 3 carboncast steel (SC450) is used.Table 3.1Mechanical properties(1) Mechanical properties of gray cast iron(2) Mechanical properties of spheroidal graphite cast iron(3) Mechanical properties of carbon cast steelPlummer Block and Bearing MaterialsTable 3.2Plummer block accessories materialsTable 3.3Adapter materials3.2 Bearing materialsRaceway and rolling element materialsWhen the contact surfaces of a bearing raceway and rolling elements are repeatedly subjected to heavy stress,they still must maintain high precision and running accuracy. To accomplish this, the raceway and rolling elements must be made of a material that has highhardness, is resistant to rolling fatigue, is wear resistant, and has good dimensional stability.By using pure materials, low in these non-metallic impurities, the rolling fatigue life of the bearing is lengthened. For all NTN bearings, pure material is prepared which has low oxygen content and low non-metallic impurities, by vacuum degassing process and secondary refining process.Cage materialsBearing cage materials must be strong enough to withstand the vibration and shock load occurring on running bearings, develop limited friction with rolling elements and bearing ring, be light, and resist the heat occurring on running bearings.The cages for small- and medium-sized bearings are pressed cages prepared through pressing process with cold or hot rolled steel plate, while the cages for large-sized bearings are machined cages made of cast high tensile brass or carbon steel for machine structural purposes.Strength of Plummer Blocks, and Combination with Bearings4. Strength of Plummer Blocks, and Combination with Bearings4.1 Strength of plummer blocksThe disruptive strength of plummer block varies depending on its type, nature and direction of a loadworking on it, as well as the flatness of a surface to which it is installed. The typical trend of static disruptive strength of SN5 and SN6 (S6) series of cast iron plummer blocks is plotted in Figs. 4.1 and 4.2respectively.When selecting a plummer block, the safety factors in Table 4.1must be considered. Also, a higher grade of flatness is required of a surface for mounting a plummerblock.Table 4.1Safety factors of cast iron plummer blocks To counter a horizontal or axial load, the face of the bed must be secured with a stopper.For applications where extreme shock load is present or a fractured plummer block can lead to severe accident, NTN offers special plummer blocks made of spherical graphite cast iron or cast steel. For further information, contact NTNEngineering.Fig. 4.1 Static disruptive strength of SN5 series Fig 4.2 Static disruptive strength of SN6 (S6) seriesStrength of Plummer Blocks, and Combination with Bearings4.2 Combinations of plummer blocks and bearingsThe typical plummer block-bearing combinations are listed inTables 4.2 (1) and (2).Table 4.2 (1) Plummer blocks and applicable bearingsStrength of Plummer Blocks, and Combination with BearingsTable 4.2 (2) Plummer blocks and applicable bearingsExample of application with cylindrical roller bearing Example of application with deep groove ball bearingAllowable Speed 5. Allowable SpeedGreater bearing speed leads to higher bearing temperature owing to friction heat occurring within the bearing. When the bearing is heated beyond a specific limit, a bearing failure such as seizure occurs, and the bearing cannot maintain stable operation any more. The limiting bearing speed where a bearing can operate without developing heat beyond a particular limitation is called allowable speed (rpm). This varies depending on the type and size of bearing, type of cage, as well as loading, lubricating and cooling conditions.The bearing tables in this brochure summarize the typical allowable bearing speeds either with grease or oil lubrication. However, these values assume that:¡An NTN standard design bearing having correct internal clearance is correctly installed.¡The bearing is lubricated with quality lubricant, and the lubricant is replenished or replaced at correct intervals.¡The bearing is operated under normal loading conditions (P 0.09C r, F a/F r 0.3), and at a normal operating temperature.Note, however, that rolling elements may fail to rotate smoothly under a load of P 0.04C or. For advice against this problem, contact NTN Engineering. Also, note that the allowable speed of deep groove ball bearing having a contact seal (model LLU) or low-torque seal (model LLH) is governed by the peripheral speed of the seal. The allowable speed of a bearing that is used under severe operating conditions can be determined by multiplying the allowable speed of that bearing in a bearing table by an adjustment factor in Fig. 5.1.The allowable speed of a plummer block with a bearing varies depending on the seal type used. For example, in the case of a plummer block having a contact seal, its allowable speed is restricted by the allowable peripheral speed of the seal. Fig. 5.2provides a guideline forselecting allowable peripheral speeds of various seals.Fig. 5.1 Values of adjustment factor f L dependent on bearing load C: Basic dynamic load rating NP: Dynamic equivalent load N1Determine the allowable speed of the seal of a cylindrical bore bearing by referring to the shaft diameter at the contact surface of the seal.In the plotting above, the allowable speeds of the seal are indicated as shaft speeds (rpm).Fig. 5.2 Allowable speed of bearing vs. allowable peripheral speed of seal n oBearing Seals6. Bearing SealsThe purposes of bearing seals are to prevent lubricant from leaking out and to protect the bearing against ingress of dust and moisture.An appropriate bearing seal is selected considering the lubricant type (grease or oil) and the peripheral speed of the seal.The seal type of NTN plummer blocks can be either contact or non-contact type. The contact type is available as felt seals and rubber seals, while the non-contact type as labyrinth seals. Also, special combination seals are available for applications under severe operatingconditions involving, for example, heavy air-borne dust.6.1 Contact seals(1) Rubber seal (Fig. 6.1)Rubber seals are typically used for grease lubrication,and their allowable peripheral speed, as a guideline,ranges from 5 to 6 m/s.Usually, the material of rubber seals are nitrile rubber.However, to cope with demanding ambient temperatures,the materials in Table 6.1are also available.(2) Felt seal (Fig. 6.2)Felt seals are compatible with rubber seals, but must be used for grease lubrication only.Felt seals are not suitable for dusty or moistenvironments. Their allowable peripheral speed, as a guideline, is 4 m/s max. A felt seal can be cut into two pieces that are respectively fitted into the seal grooves on the upper and lower plummer block housings. This feature greatly simplifies the assembly procedure forplummer blocks.Fig. 6.1 Rubber sealFig. 6.2 Felt seal: Excellent, : Good, : Fair, : Poor (must not be used)Table 6.1 Types and features of rubber seal materialsBearing SealsFig. 6.4 Labyrinth sealFig. 6.6 Combination sealFig. 6.5 Special labyrinth seal(3) S grease seal (Fig. 6.3)The S grease seal (synthetic rubber seal with spring)excels in sealing performance and is well suited for grease or oil lubrication. Custom specification variants can be used in a plummer block.Its recommended peripheral speed falls within a range of 10 to 12 m/s. The surface roughness and hardness of the shaft in contact with this sealing material necessitates special attention.6.2 Non-contact seals(1) Labyrinth seal (Fig. 6.4)The labyrinth seal used in the bore of plummer blocks --SD31 TS and SD32 TS series-- comprise a labyrinth ring that is fitted into the bore of the plummer block. A labyrinth seal is used in clearance fit to a shaft (h9)together with an O-ring so that it can be readily installed and can follow expansion/compression of the shaft.This seal type excels in sealing performance, and can be used for grease or oil lubrication.(2) Special labyrinth seal (Fig. 6.5)The special labyrinth seals such as those in Fig. 6.5are very useful for applications where heavy soil and dust are present.The plummer blocks used in conjunction with this seal type are manufactured per custom specifications. For further information, contact NTN Engineering.Shaft design specification for the area in contact with the seal The quality of a shaft section in contact with the seal lip greatly affects the sealing performance of the seal.Therefore, strictly adhere to the design standard for shafts in Table 6.2.6.3 Combination sealsThe combination seals used for the SBG series are unique seals that comprise both of an oil seal andlabyrinth seal and are installed in the bore of a plummer block. They are used in environments where heavy dust and contaminants are present.For better sealing effect, the labyrinth seal is often filled with grease.With a continuous or intermittent lubrication scheme, lubricant can tend to leak. Use a sealthat positively offers reliable sealing.Table 6.2 Shaft design standardFig. 6.4 Labyrinth sealShaft Design7. Shaft Design7.1 Bearing-to-shaft fitThe tolerance requirements of the shaft outsidediameter differs between a bearing with an adapter and a cylindrical bore bearing each mounted to a plummerblock. Table 7.1summarizes the recommended bearing-to-shaft fits.A bearing with an adapter is installed to a shaft bymeans of an adapter. A cylindrical bore bearing is usually positioned in interference fit by a shaft shoulder and secured with a nut and washer. For this application, the shaft is provided with threading and washer groove as illustrated in Fig. 7.1.Fig. 7.17.2 Mounting dimensionsTo be able to correctly seat a cylindrical bore bearing to the shaft shoulder, the height and fillet radius r as of the shoulder must be greater than the chamfering r s min of the bearing as specified in Table 7.2.If the bearing is used on the shaft end, the configuration must be designed such that the shaft end does not interfere with the face of bearing bore. For reference,Table 7.3provides the wall thickness values at thebearing bore.1 The shoulder height must be greater than that specified when the shaft is subjected to a greater axial load.Table 7.2 Fillet radius and shoulder height of shaftTable 7.1 Recommended bearing-to-shaft fitShaft DesignNote: The dimensions for model SN3 are the same as those of model SN2.The dimensions for SD30 and SD31 are the same as those of SD33 and SD34.(1)(2)Table 7.3 Wall thickness at the bearing boreLubrication8. Lubrication8.1 Grease lubricationUsually, plummer blocks are lubricated with grease.Grease lubrication leads to good sealing performance and simpler seal design.(1) Characteristics of greaseGrease is prepared by mixing base oil such as mineral oil or synthetic oil with thickener. The characteristics of grease vary depending on types and combination of various additives.The typical grease types and their characteristics are summarized in Table 8.1.Depending on the intended application, a grease of appropriate consistency number is used as summarized in Table 8.2.(2) Grease volumeWhen grease is packed into a bearing, the inside of the bearing is first filled with grease. During this course, the grease must be also filled into the inside guide way of the bearing cage.As a guideline, the recommended volume of grease filled in plummer blocks is given below.General application⋯⋯⋯⋯About 1/3 to 1/2 the empty spaceRelatively high speed application⋯⋯⋯⋯⋯⋯⋯About 1/2 the empty spaceLow speed application⋯⋯⋯⋯⋯More than 1/2 the empty space The volume of grease should be carefully selected as it can lead to overheating of the bearing, outward leakage from the seal, or ingress of dust.The recommended volume of grease commonly filled in the applicable bearings are summarized in Table 8.3.Table 8.2 Grease consistencyTable 8.3 (3) Volume of grease filled into models SN30 and SN31Table 8.3 (1) Volume of grease filled into models SN5 and SN6Table 8.3 (2) Volume of grease filled into model SDHandling the Plummer Blocks and Bearings9. Handling the Plummer Blocks and BearingsRolling bearings are precision components. To maintain their accuracies, they must be handled very carefully. In particular, they must be kept clean, not be subjected to strong impact, and be protected against possible rusting.Plummer blocks also need similar handling practices.9.1 Inspection before installationBefore installing a bearing and a plummer block, the following points must be thoroughly checked and inspected.(1) Prepare installation tools, measuring instruments, oil stone, lubricant and factory cloth. Before theinstallation work, remove dust and impurities from these tools. (Fig. 9.1)(2)Make sure that the shaft is free from bends or other damages and that it has been dimensioned and formed as specified. (Fig. 9.2)(3)Remove dent marks (even though very small) from the mating faces with an oil stone or fine emery paper. Check that the contact face to the seal has specified surface roughness (0.8a). Wipe dust away from the shaft with clean factory cloth.(4)Remove possible dust and metal chips from the inside of plummer block.(Fig. 9.3)Fig. 9.1Fig. 9.2(5)Check the flatness of the mounting face of the plummer block. (When placed on a frame, the plummer block must be stably seated.)9.2 Preparation for installing the bearing(1)Unpack the bearing just before the installation work.(2)If the bearing is to be grease-lubricated, the rust-proof coating on it may remain unremoved. If it is to be oil-lubricated, remove the coating with benzene or kerosene.(3)For a bearing with an adapter, check its radial clearance before the installation work. To do so,place it on a flat work bench, and fit a thicknessgage between the uppermost roller and the raceway surface on the outer ring to measure the clearance (Fig. 9.4). Do not force the thickness gage in or turn the bearing. Otherwise, the resultant clearance measurement will be greater than the actual clearance.Fig. 9.3Fig. 9.4Handling the Plummer Blocks and Bearings9.3 Installation of the bearing and associatedcomponentsOnce careful checking is complete, install the bearing and associated components. For the positional relationship, see Fig. 9.5.Fig. 9.5Fig. 9.7When a bearing is installed onto a shaft or into a housing, do not directly hit its end face with a hammer or drift as shown in Fig. 9.6. Otherwise, its design performance can be lost. Always evenly exert force around the entire bearing ring face. Also, do not apply force to one bearing ring (for example, outer ring) as in Fig. 9.7to convey the force via the rolling elements to the other bearing ring (inner ring) to install the latter.Otherwise, a dent mark or other damage can occur on either or both rings.When installing a cylindrical bore bearing, whose interference is relatively small, its whole inner ring can be uniformly press-fitted at an ordinary temperature as illustrated in Fig. ually, the inner ring is press-fitted by tapping the sleeve with a hammer. However,when many bearings must be installed at a time, a mechanical or hydraulic press will be helpful.When installing a non-separable bearing to the shaft and housing at a time, apply a press-fitting force to both the inner and outer rings by using a pressure distribution pad as in Fig. 9.9.Handling the Plummer Blocks and Bearings9.3.1 Bearing with an adapter(1)Thinly apply highly viscous mineral oil to the taper,threading and the chamfered face of the nut (see Fig. 9.10)before press-fitting. In particular, apply molybdenum bisulfide paste to these areas on a large bearing. This prevents scuffing, and allows easy bearing removal. Before the installation work,remove oil from the shaft and the bore face of sleeve with a clean factory cloth.(2)Mount the adapter to a correct position considering the dimension B 1, B 2or B 3in the bearing table.When fitting the adapter sleeve onto the shaft, openFig. 9.10Table 9.1 Installation of tapered bore self-aligning roller bearingsthe slit with a flat-blade screwdriver for easy fitting.FIg. 9.11(3)Fit the bearing over the adapter sleeve on the shaft as tight as possible, so that the bearing inner ring is fully seated onto the taper on adapter sleeve.(4)Lightly tighten the nut until the sleeve is seated on the shaft.(5)When fully tightening a self-aligning ball bearing,make sure that its radial clearance becomes approximately 1/2 that before fitting. For a self-aligning roller bearing, tighten the nut whilemeasuring its radial clearance with a thickness gage so that the reduction of radial internal clearance value in Table 9.1is reached. Make sure that an installed self-aligning ball bearing can turn smoothly by hand (ss Figs. 9.12 and 9.13).Fig. 9.11。
