Ball screws are ideal for converting rotary motion into linear motion or linear motion into rotary motion. Ball screws consist of a screw, nut, steel ball, preloader, reverser and dust collector.

Ball screw is a transmission element used on tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion or torque into axial repeated force, while both high precision, reversibility and high efficiency, due to a small frictional resistance, ball screw is widely used in various industrial equipment and precision instruments.

The ball screw consists of a screw, nut, steel ball, preloader, reverser and dust collector. Its function is to convert rotary motion into linear motion, which is a further extension and development of the Acme screw. The importance of this development is that the bearing is transformed from a sliding action into a rolling action.
