SLK – SBC Precision Rolled Ball Screw

A ball screw achieves high efficiency even if driving torque is low because balls roll between the screw
shaft and ball nut to obtain a lower coefficient of friction than a leadscrew.
● Low Coefficient of Friction and High efficiency
●High Velocity and Acceleration.
● Long Service Life Time.
