直线轴承介绍

·直线轴承介绍：

直线轴承是一种以低成本生产的直线运动系统，用于无限行程与圆柱轴配合使用。这类轴承由一个外套圈，多列球和一个保持架构成(保持架有尼龙保和铁保两种,一般为尼龙保)。由于承载球与轴呈点接触，故使用载荷小。钢球以极小的磨擦阻力旋转，从而能获得高精度的平稳运动。球的列数越多，摩擦力就越小。

Linear Bearing is a kind of linear motion system produced based on low cost. It makes linear reciprocating displacement on a matching cylindrical shaft. This type bearing consists of a sleeveed outer ring.multi-row balls and a retainer. The balls are point-contacted with the shaft and run under tiny friction, so that the bearing have long running life and easy maintenance and replacement. The more the ball rows are,the less the friction force is.

直线轴承广泛用于纺织机械, 印刷机械,电动工具,医药机械,精密机床,电气切割,自动记录仪和办公设备等。

It is widely used in the textile machinery, the printing mechanism, the power tool, the medicine mechanical, the precision machine tool, the electrical cutting, the self-recording instrument and the office equiment etc.

*润滑与磨擦

*脂润滑

直线轴承内部注入防蚀油，若用油脂润滑时，先用煤油或有机溶济清除防蚀油，风干后再添加润滑脂。

建议使用粘性标记为N0.2的锂皂润滑脂.

*油润滑

若用油润滑时,不必清除防蚀油,根据温度变化可选用ISO粘度等级VG15-100的润滑油.轴润滑可从供油管给没,或从外轴承座上的油孔给油。由于密封圈会刮掉润滑油，油润滑不适用无孔的带密封圈轴承。
