7603 series Ball Screw Support Bearing is made in a high purity bearing steel for inner and outer rings with a contact angle of 60° and more steel balls. This series of bearings have greater axial stiffness than tapered roller bearings and cylindrical roller bearings. With a small starting torque and low driving force can achieve precise running. The paired use can bear both axial and synthetic loads, rolling elements guided with nylon cage.
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.
