迁安Bearing Steel Tube

Bearing steel pipe refers to hot rolled or cold rolled (cold drawn) seamless steel pipe used for manufacturing ordinary rolling bearing rings. The outer diameter of the steel pipe is 25-180 mm, and the wall thickness is 3.5-20 mm, which is divided into ordinary precision and higher precision.

There are the following types of special bearing steel for producing bearing steel pipes (G marked with "roll"): chromium bearing steel, such as GCr6, GCr9 (SiMn), GCrl5 (SiMn); Chromium-free bearing steel such as GSiMnV (Re), GSiMnMoV (Re), GMnMoV (Re); Carburized bearing steel such as G20CrMo, G20Cr2Mn2Mo; High carbon chromium stainless bearing steel, such as 9Cr18 (Mo), etc.
