What is the purpose of bearing lubrication？

The purpose of bearing lubrication is to reduce internal friction and bearing wear. Its lubrication effect is as follows.

 1. Extend rolling elements fatigue life

If the rolling contact surface is well lubricated during rotation, the fatigue life of the rolling element of the bearing will be prolonged. On the contrary, if the oil viscosity is low and the lubricating oil film thickness is not good, the fatigue life of the bearing rolling element will be shortened.

 2. Prevent bearing from overheating

Circulating oil supply can be used to dissipate the heat generated by friction, or heat transmitted from the outside to cool the bearing. Prevent bearing overheating and lubricating oil from aging.
