The major characterizations of the prs thin-section ball bearing are that, light weight, sufficient rigidity, small section, and the excellent load bearing performance. The thin-section ball bearings produced by our prs company totally have three kinds of structural, are divided into five series. Among them, the sections which change with the hole diameter are two times of the steel ballsí» diameter ..The diameter unit usually is inch. We produce bearings according to the customersí» blueprint re. At present , each series of them are widely applied in aircraft , aerospace and astronomy instrumentation, fixing and work holding equipment , food processing equipment , glass working equipment , index and rotary tables , packing equipment , machine tools , medical devices , optical scanning equipment , radar, satellite and communications equipment , robotics , textile machinery , tube and pipe cutting machines, semiconductor manufacturing equipment , sorting equipment and so on in all the various trades and occupations.
