Hiwin ball screws are precision mechanical components used to convert rotational motion into linear motion or vice versa. They consist of a screw shaft with a helical groove and a ball nut with recirculating ball bearings. As the screw shaft rotates, the ball bearings move along the helical groove, translating the rotational motion into linear motion. Hiwin offers a range of ball screw designs, including different lead (pitch) options, nut configurations, and end support types, allowing users to select the most suitable option for their specific application requirement. They provide precise linear motion with minimal backlash, making them suitable for applications requiring tight positional accuracy.
