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.
Gear Coupling
Duff-Norton provides three coupling types which have been tailored to specific actuator requirements: Chain, Jaw, and Flex Rigid.
Gear Couplings
- Integrates well with Duff-Norton mid and larger capacity actuators.
- High torque capacities.
- Standard ANSI dimensions, straight bore diameters.
- Common bore diameters may be custom ordered.
- Special bore diameters may be custom ordered.
- Long service lives.
- Easy fit onto the actuator’s worm shaft.
- Allows for incremental system adjustments.
