How does a recirculating ball screw work
WebApr 17, 2015 · To recap, a planetary roller screw is a screw assembly that uses rollers instead of balls. The rollers are threaded to allow movement along the length of the screw, and are geared to spin as the nut turns, eliminating the need for recirculation. http://www.barnesballscrew.com/how-a-ball-screw-works/
