The purpose of lubrication of rolling bearings is to reduce internal friction and wear of the bearing and prevent burning. Its lubricating effect is as follows:

1. Reduce friction and wear

In the contact part of the ring, rolling element and cage that constitute the bearing, metal contact is prevented, and friction and wear are reduced.

2. Extend fatigue life

The rolling fatigue life of the bearing is prolonged when the rolling contact surface is well lubricated during rotation; on the contrary, the oil viscosity is low, and the lubricating oil film thickness is not good, then it is shortened.

3. Discharge friction heat and cool down

The circulating oil method can use oil to remove heat generated by friction or heat transferred from the outside and cool. Prevent the bearing from overheating and prevent the lubricant from aging.

4. Other

It also has the effect of preventing foreign matter from intruding into the bearing, or preventing rust and corrosion.
