Ball screws are ideal products for converting rotary motion into linear motion, or converting linear motion into rotary motion. Ball screw is a commonly used transmission component in tool and precision machinery. It consists of a screw, nut, steel ball, pre press plate, reverser, and dust collector. 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.
