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.

FEATURES & BENEFITS
SUPERIOR SEALING PERFORMANCE
Bellows Sealing System provides superior sealing performance throughout the wear life of the Rotary Union.
DESIGNED FOR DIRTY MEDIA APPLICATIONS
Debris in contaminated media will not be captured in the Bellows Sealing System, which reduces clogging.
MAINTENANCE FREE
The 9000G is maintenance free because there is no rolling element bearing, therefore no lubrication is required.
HIGH TEMPERATURE APPLICATIONS
Offers the same design as the standard 9000 Series, but utilizes carbon graphite bearings for high temperature applications.
IDEAL FOR HIGH TEMPERATURES
The thrust collar allows for thermal expansion, making this an ideal union for high temperature, general purpose applications.
