Duff-Norton Modular Actuators

Duff Norton modular actuators are made for a variety of applications. They are custom made by matching standard actuators with electric, air, hydraulic or explosion proof drive units.
Duff Norton translating tube machine screw models feature a traveling lift nut which allows precise load positioning. Translating tube actuators are used when environmental contamination is anticipated as they have an enclosed lifting screw and translating tube. For use in locations relatively free of dust, dirt and moisture.
Optional limit switches and transducers are available on the translating tube machine screw modular actuator.
Ball Screw Jacks
Screw Jacks - 1/4 to 350 Ton
1/2-to-50-ton capacity. Ball Screw Jacks provide high efficiency and high speed in one linear positioning package. These actuators come in many standard models, or can be custom designed for any application up to 50 tons. The positive action of the low friction ball screw and nut design provides longer life at load and requires less power to achieve a specified thrust. Ball screw actuators can be used individually, in tandem or as part of a larger mechanical system. With lifts up to 20 feet, Duff-Norton Ball Screw actuators offer the perfect solution to many linear positioning applications.
- Requires less power by providing positive mechanical action.
- Long predictable ball screw and ball nut life.
- Ball screw actuators can be used individually, in tandem or as part of a larger mechanical system.
- Move loads and apply force more efficiently than other mechanical actuators.
- Ball screw jacks reliably handle full loads in tension or compression.
- Ball screws permit faster operation and longer life under heavy loads.
