For achieving ultrahigh rotation (7,000rpm) and high precision (TIR:0.003), one can get this Rolling Center from us. This is basically attached to a carbide tip for preventing abrasion and friction which comes because of ultrahigh rotation. Moreover, this Rolling Center is manufactured with three rows angular bearings and a needle bearing. Also, its parts are assembled meticulously in order to tolerate stiffness. Also, in this rolling center an original(non-contact)labyrinth mechanism is adopted for preventing the penetration of cutting oil. For special cases please contact us like if a grinding machine is used, the V seal need to be used.
