Bearing steel is also known as high-carbon chromium steel. The carbon content Wc is about 1%, and the chromium content Wcr is 0.5%-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 antimagnetic bearing steel.

Application |
Applied in various fields of industrial production, including rolling bearings for high-speed wire rod mills, rolling bearings for large-scale machinery equipment (cement bearings, slewing bearings) and ordinary mechanical bearings, machine tool screws, etc. |
Application:
Bearing steel is a steel grade used to manufacture rolling bearing balls, rollers and sleeves. It can also be used to make precision measuring tools, cold punching dies, machine tool screws, such as punching dies, measuring tools, taps, and precision parts for diesel oil pumps. Bearing steel is the steel used to make balls, rollers and bearing rings.
