Bearing lubrication is also an important part of bearing components. The selection of lubrication methods and lubricants directly affects the life of bearings, according to different use conditions, because the selection of the most appropriate lubrication.

Lubrication effect:

(1) Reduce friction and wear: lubrication can reduce the rolling friction between the rolling body and raceway, sliding friction between the rolling body and cage, cage and ring sliding friction

(2) Reduce the generation of heat: eliminate the heat generated inside the bearing or heat transmitted from the outside, prevent the bearing overheating and lubricant deterioration.

(3) Rust prevention and dustproof effect: prevent the rust of rolling body, cage and bearing ring, prevent magazines and water from entering the bearing interior.

Characteristics of lubricants:

(1) Low friction, low wear.

(2) Good heat resistance and heat transfer.

(3) Oil film strength.

(4) No corrosion.

(5) good dust and water resistance.

(6) Stable viscosity.
