What is bearing steel? What are the characteristics of bearing steel?
It is steel used to make balls, rollers and bearing rings. Bearing steel, also known as high carbon chromium steel, has a carbon content of ωc of about 1% and a chromium content of ωcr of 0.5% to 1.65%. Bearing steel is divided into six categories: high carbon chromium bearing steel, chromium-free bearing steel, carburized bearing steel, stainless bearing steel, medium and high temperature bearing steel and anti-magnetic bearing steel.
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 most demanding steel grades in all steel production.
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 stamping dies, machine tool screws, precision parts such as dies, gauges, taps and diesel oil pumps.
