Description
Description:
Bearing steel tube is a sort of hot-rolled or cold-rolled (cold-drawn) seamless steel tube. 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
Dimension & Tolerance:
Hot Rolled tube range: OD 60-210mm, WT 5-55mm
Cold-drawn/Cold-rolled tube range: OD 10-135mm, WT 1-20mm
Tolerance of OD: D<50 mm (-0/+0.15mm), D>50 mm (-0/+0.25mm)
Tolerance of WT: -/+7.5%(after agreement -/+5%)
Straightness: 1 mm/m measured on the outside surface, maximum 2.5 mm/3000mm
