Ball screw is a transmission element often used in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion or torque into axial repeated force. At the same time, it has the characteristics of high precision, reversibility and high efficiency. Due to its small friction resistance, ball screw is widely used in various industrial equipment and precision instruments.
The ball screw is composed of screw, nut, steel ball, prepress, reverser and dustproof device. Its function is to transform rotary motion into linear motion, which is a further extension and development. The significance of this development is to change the bearing from sliding action to rolling action.
