Introduction to Ball Screw
A ball screw is a mechanical linear actuator that translates rotational motion into linear motion with the use of ball bearings. It consists of a screw shaft, a nut, balls, and a ball return mechanism. The balls roll between the screw shaft and the nut, reducing friction and enabling high-precision linear movement. Ball screws are widely used in various industries, such as machine tools, robotics, aerospace, and automotive, due to their high efficiency, accuracy, and long service life.
