Ball Screw Actuators move loads and apply force more efficiently

The Duff-Norton Ball Screw Actuator range gives you a single- package, positive-action linear actuator which can be driven by an electric, air or hydraulic motor. A ball-bearing type heat treated screw and mating nut with rolling contact reduces friction to a bare minimum in converting torque to thrust.

Overall operating efficiency is as high as 70% in some models, depending on the ratio of the worm gear set. Because our ball screw actuator unit has been carefully engineered and pretested, you no longer have to purchase components from different suppliers and design your own system to achieve high levels of efficiency. So you save design, set- up and testing time.

Duff Norton Ball Screw Actuators are available in standard models and Continuous Duty Cycle type featuring oil bath lubrication for continuous operation applications.
