Many people know something about linear bearings and joint bearings, but they don't seem to know much about bearing steel. The so-called bearing steel refers to the steel used to make balls, rollers and bearing rings. It is a special steel. High-quality linear bearings and joint bearings are inseparable from high-quality bearing steel.
Bearing steel is also called high-carbon chromium steel, with a carbon content of about 1% and a chromium content of 0.5%-1.65%. Bearing steel is divided into six categories: high carbon chromium bearing steel, chromium-free bearing steel, carburized bearing steel, stainless steel bearing steel, medium and high temperature bearing steel and antimagnetic bearing steel.
Bearing steel has high and uniform hardness and wear resistance, and high elastic limit. The requirements for the uniformity of the chemical composition of the bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict. It is one of the most stringent steel grades in all steel production.
