Dec 05, 2018

Three. Hardness
Hardness is one of the important qualities of bearing quality, which has indirect influence on contact fatigue strength, wear resistance and elastic limit. The hardness of bearing steel should reach HRC61 ~ 65 in operation condition, which can make the bearing obtain higher contact fatigue strength and wear resistance.
Four. Rust preventive properties
In order to avoid corrosion and rusting of bearing parts and finished products in the process of processing, sending and operation, it is requested that bearing steel should have good anti-rust performance.
