What is a ball screw？

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

A ball screw consists of a screw, nut, steel ball, pre press plate, reverser, and dust collector. Its function is to convert rotational motion into linear motion, which is a further extension and development of the Ekm screw. The significance of this development is to transform bearings from sliding motion to rolling motion.

The history of people using screws for transmission is actually not very long. Traditional screws have always had poor positioning and are prone to damage. Until 1898 AD, people first attempted to place steel balls between nuts and screws using rolling friction instead of sliding friction to improve their poor positioning and susceptibility to damage. In 1940, ball screws were further incorporated into automotive steering systems, marking a significant revolution in the application of ball screws and gradually replacing traditional ACME screws. Until recent years, ball screws have become one of the most widely used components in the industry
