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.
Flange
Flange Blocks lock on to the end of the rotating screw, and can then be bolted on to the machine or fixture. This ensures that the load being carried by the actuator’s lifting nut is properly guided.
- Ductile iron housing - for extra strength vs. the standard gray iron.
- Setscrew locks - to properly secure the connecting shaft regardless of direction.
- Anti-rotation Pins - to help prevent random bearing movement.
