The history of people using screws for transmission is actually not very long. Traditionally, screws have always had problems with poor positioning and easy damage. It was not until 1898 that people first tried to place steel balls between the nut and the screw to replace sliding friction with rolling friction to improve its poor positioning and easy damage.

1. According to the national standard GB/T17587.3-1998 and application examples, the ball screw (which has basically replaced the trapezoidal screw, commonly known as the screw) is an actuator used to convert rotary motion into linear motion; or convert linear motion into rotary motion, and has high transmission efficiency and accurate positioning.

2. When the ball screw is used as the active body, the nut will convert the rotation angle of the screw into linear motion according to the lead of the corresponding specification. The passive workpiece can be connected with the nut through the nut seat to achieve the corresponding linear motion.
