Ball Screw Components

Ball screws are ideal products for converting rotary motion into linear motion, or converting linear motion into rotary motion.

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

The ball screw is composed of screw, nut, steel ball, preloading piece, reverser and dust protector. Its function is to convert rotational motion into linear motion, which is a further extension and development of the Acme screw. The important significance of this development is to change the bearing from sliding action to rolling action.
