Ball screw is a mechanical component that converts rotational motion into linear motion, achieved by rolling along the screw through ball bearings. Compared to traditional sliding contact screws, this design greatly improves efficiency, reaching over 90%, thereby significantly reducing energy loss. The main components of a ball screw include the ball screw shaft, ball nut, ball bearing, and seal. The ball screw shaft is a chrome steel strip with spiral grooves that form a helical shape, allowing the ball to roll in it. The ball nut is responsible for the recirculation of the ball, ensuring the continuous and efficient operation of the ball screw. The design of ball screws considers multiple physical characteristics, such as lead and ball diameter, which directly affect the performance and application range of the screw.
