Product features
contact angle of High purity bearing steel(can control strictly the detrimental oxide impurities that affect the rolling fatigue life) inner and outer rings is 60°,steel balls greater axial stiffness, compared with tapered roller bearings and cylindrical roller bearings, the starting torque is small to achieve the running with low driving force and high precision; the paired use can bear both axial load and synthetic load, rolling element guided nylon cage.

Sophia Super Precision Ball Screw Support Bearing is specially designed for machine tool applications. Contact angle is high at 65 to provide axial rigidity and the very high thrust capacity. including 7602.., 7603..BS series.etc.
