Planetary Screws

Converting rotary motion to linear movement, the system consists of a multi-start screw with an involute thread form and a number of planetary rollers with annular grooves, which engage with the screw. The rollers also engage with a grooved load bearing element, which transmits the load through roller thrust bearings, to the nut housing. The rolling action results in a high efficiency mechanism, while the line contact and hardened and ground construction achieve a high dynamic load carrying capacity, together with almost no axial backlash or wear. Planetary Roller Screw is ideally suited for applications in Nuclear engineering, Areospace, Metal processing, Medical, food processing and Offshore and Marine industries. Possible applications include: Robotics, Laser tracking, Simulators, Medical scanners and more. Load capacity from 45KN to 1200KN,high efficiency, high positional accuracy, long life, low maintenance, low noise.
