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
HEAVY DUTY DESIGN
Designed with two ball bearings spaced to withstand radial and thrust loads.
NO LEAKAGE IN TOUGH APPLICATIONS
Compression springs in the 2000 Series provide even loading across the seal surfaces to maintain zero leakage even in low pressure applications.
EASY MAINTENANCE
Designed with an integral flange that allows repairs without removing the housing from the machine.
EASY MOUNTING
The flange attaches directly to the machine journal, providing inherently concentric mounting, minimizing overhang, and partially relieving bearing load to increase service life.
