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.
Bellows Boots
The use of a bellows boot for is highly recommended most actuator applications. Duff-Norton can provide bellows boots for the most stringent application requirement.
- Protects the lifting screw from: dust, dirt, moisture, and corrosive contaminants.
- Helps maintain the proper lubrication.
- Can be provided for all actuator screw end types and configurations.
- Standard bellows boots are made of neoprene coated nylon with sewn construction.
- Special bellows boots can be provided with a variety of materials for applications involving high temperatures, highly corrosive atmospheres, and other special conditions.
- Bellows boots can also be provided from molded materials, with internal or external guides to prevent sagging, and with zippers for easy installation or removal.
