The purpose of lubrication of rolling bearings is to reduce internal friction and wear of the bearings. Prevent burning and its lubricating effect is as follows:
1 reduce friction and wear:
In the mutual contact part of the ferrule, rolling element and retainer that constitute the bearing. Prevent metal contact and reduce friction and wear.
2 prolong fatigue life:
The rolling fatigue life of the bearing is prolonged when the rolling contact surface is well lubricated during rotation.
Conversely, the oil viscosity is low. The thickness of the lubricant film is not good. Then shortened.
