Hiwin Recirculating Ball Screws are designed to provide smooth and precise linear motion with high accuracy and repeatability. They consist of a screw shaft, a ball nut, and a set of recirculating ball bearings.
The screw shaft has a helical groove cut into its surface, which serves as a track for the ball bearings. The ball nut, which is mounted on the end of the screw shaft, contains the ball bearings and serves as a guide for them as they circulate the screw.
