Ball Screw Bearings
The Ball Screw is a highly efficient feed screw with balls rolling between the screw shaft and the nut. Compared to conventional sliding screws, the maximum driving torque is only one-third of that of a ball screw, which makes it extremely suitable for saving the power of drive motors.
● High precision
● Widely used because of its low frictional resistance.
