Introduction
Bearing steel is used for the manufacture of rolling bearings such as balls, rollers and sleeves. It can also be used to make precision measuring tools, cold die, machine screw and diesel oil pump precision parts. Bearing steels have high and uniform hardness and wear resistance, as well as high elastic limits. The uniformity of the chemical composition of the bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are all very strict, and it is one of the steels required to be strict in all steel production.
