Product features:

High purity bearing steel(can control strictly the detrimental oxide impurities that affect the rolling fatigue life)for inner and outer rings, contact angle of 60°, more number of steel balls etc greater axial stiffness, compared with tapered roller bearings and cylindrical roller bearings, the starting torque is small that 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.

Ball screw support bearings are specially designed for machine tool applications. Contact angle is high at 65 to provide axial rigidity and the very high thrust capacity. Also available are the 7602.., 7603.. and BS series.

Speed factor

Grease lubrication DmN≤400000 that the limiting speed N≤400000/Dm Dm—Bearing mean diameter


Applications:

Screw support for CNC lathe, screw support of CNC universal grinding machine, screw support of automatic CNC bearing rings grinding machine, screw support of CNC machining centers and other kinds of screw support of CNC precision transmission machinery.
