Ballscrews, also known as ball bearing screws or recirculating ballscrews, are used in a wide range of applications across virtually all areas of industry. They convert rotary motion into linear motion. Between the shaft, more precisely the threaded shaft, and the nut, the balls roll infinitely via a ball recirculation system, guaranteeing frictionless motion for your application.
