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.
