bearing pipes

Bearing steel tubes are hot-rolled or cold-rolled (cold-drawn) seamless steel tubes for the manufacture of ordinary rolling bearing rings. The outer diameter of the steel pipe is 25-180 millimeters, the wall thickness is 3.5-20 millimeters, divided into two kinds of ordinary precision and higher precision.
Bearing steel is used to manufacture balls, rollers and bearing rings. Bearings are subjected to great pressure and friction in their work, so bearing steel is required to have high and uniform hardness and wear resistance, as well as 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, and it is one of the most demanding steel grades in all steel production.
