What is a ball screw?

Ball screw is an ideal product for converting rotary motion into linear motion, or for converting linear motion into rotary motion.

Ball screw is the most commonly used transmission component in both tool and precision machinery. Its main function is to convert rotational motion into linear motion or torque into axial repeated force, while also possessing the characteristics of high precision, reversibility, and high efficiency. Due to its small frictional resistance, ball screws are widely used in various industrial equipment and precision instruments.

The ball screw is composed of a screw, a nut, a steel ball, a pre press plate, a reverser, and a dust collector. Its function is to convert rotary motion into linear motion, which is a further extension and development of the Akram screw. The important significance of this development is to transform the bearing from sliding motion to rolling motion.
