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.
Continuous Duty Screw Jacks
Screw Jacks - 1/4 to 350 Ton
3,500 to 27,000 pound load capacity. Continuous Duty Cycle actuators are specifically designed for continuous operation. The gear set in these actuators operate in an oil bath for thermal efficiency and long life. The shell is made of a finned aluminum for better cooling properties. Additionally, the Duff-Norton ball screw system increases these models efficiency.
