滚动轴承具有启动灵敏、磨擦力矩小、效率高、润滑方法简便、易于互换的优点,所以普遍用于作各类机械设备的支承零件。滚动轴承的回转精度和工作寿命不但取决于设计条件,而且还取决于它的工作条件,只有密封良好、环境清洁、润滑充分,才能保证其回转精度和工作寿命。如果离开上述三点环境基础,就会导致轴承迅速损坏。 Rolling bearing with a sensitive start, small friction torque, high efficiency, lubrication method is simple, easy to exchange advantages, it is widely used for various types of mechanical equipment supporting parts. Rolling accuracy and working life of the rolling bearing not only depends on the design conditions, but also depends on its working conditions, only a good seal, the environment clean, fully lubricated, in order to ensure its slewing accuracy and working life. If you leave the three environmental basis, it will lead to rapid bearing damage.
