Steel used in Bearing manufacturing

Bearing steel is the steel used to make balls, rollers and bearing rings. Bearing steel has high and uniform hardness, wear resistance and high elastic limit. The requirements for the uniformity of chemical composition, the content and distribution of non-metallic inclusions and the distribution of carbides of bearing steel are very strict. It is one of the most stringent steels in all iron and steel production.

JW STEEL mainly supply the round steel bar and steel wire rod for bearing production as below:
Meanwhile, wire rod size is Φ5.5~23, and round bar size is 16-600mm
