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.
Essential Platform Screw Jack
Screw Jacks - 1/4 to 350 Ton
Essentials Platform Actuators - 1/8-to-10-ton load capacity. Establishing a strong foundation.
The new Essentials Platform is built on Duff-Norton’s history of reliable products and provides customers with cost effective options to meet their fundamental needs.
- Robust, cost effective solution for use in many applications
- Drop-in compatibility with many competitors screw jacks - refer to pages 5 - 7 in the Essentials Platform Design Guide for bolt pattern drawings
- Precision gearing and ACME screw construction limits backlash to a max of .015 inches
- Limited screw lengths and options make the Essentials Platform easy to specify and configure
- Developed with safety in mind - Minimum column strength of the screw is 2x higher than the screw jack’s lifting capacity. All reported column strengths are for a 6 inch screw length in a fixed-free arrangement.
