The purpose of folding bearing lubrication 

Source:https://baike.so.com/doc/5328210-5563382.html      Release time:2018/11/20 15:18:00

The rolling bearing lubrication purpose is to reduce the bearing internal friction and wear, to prevent burning stick, its lubrication effect is as follows.

To reduce friction and wear in the form of bearing ring, rolling body and touch each other part of the retainer, prevent metal contact, reduce friction and wear.

Extend the fatigue life of fatigue life of rolling bearings,

In the rotation, good lubrication performance of the rolling contact surface, the extension. On the contrary, the oil viscosity is low, the thickness of lube film is not good, is shortened. Discharge frictional heat and cooling cycle to oil can discharge by friction heat, oil, or from external heat from the cooling. To prevent hotbox, prevent aging oil itself.
