Description
Description:
Bearing steel tube is a sort of hot-rolled or cold-rolled (cold-drawn) seamless steel tube. It withstands great pressure and friction force, so bearing steel tube own high and uniform hardness and abrasive resistance and elastic max. There are strict requirements for bearing tube, particularly the uniformaity of chemical composition, non-metallic inclusion content and distribution of carbides.
Application:
It can supply for producing kinds of bearing ferules, rollers and steel balls applied in combustion engine, electric motor car, automobile, tractor, lathe, rolling machine, drilling machines, mining machinery, general machinery, as well as high-speed rotated mechanical transmission keeping.
