Planetary roller screw
45 - 1 200 kN | SPIRACON
Power Jacks
The Spiracon system consists of a multi-start screw with an involute thread form and multiple planetary rollers with annular grooves engaging with the screw. The rolling action results in a high efficiency mechanism, while the line contact and hardened and ground construction achieves a high dynamic load carrying capacity, combined with almost no axial backlash or wear and long life and low maintenance.
