Support bearings and bearing units for screw drives

High-precision Single Direction Angular Contact Thrust Ball Bearings have been developed especially for the support of ball and roller screws in machine tools. They incorporate a large number of balls and have a special internal design with a contact angle of 60° to provide superior axial stiffness. These bearings also have high axial load ratings, high running accuracy together speed and acceleration capability and low frictional torque.
