High wear resistance 、High efficiency：
The ball screw operates by rolling the ball in the nut, which is more efficient than the traditional sliding screw. The required torque is only less than 1/3 of the traditional sliding screw. So it's easy to turn linear motion into rotary motion.
No Backlash and High Rigidity ：
Make the steel ball and groove have the best contact for easy movement. If proper pre-pressure is added to eliminate the clearance in the axis direction, the ball screw can have better rigidity, reduce the elastic deformation between the ball and the nut and screw, and achieve higher accuracy.
