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.

Industrial screw jacks are used to lift, position (push, pull, tilt, roll, etc.) and support all kinds of loads. Some applications where our screw jacks have been used include plastics machinery, beverage bottling systems, aircraft assembly and paper production.
Duff-Norton’s collection of screw jacks range from mini screw jacks supporting up to 1,000 pounds to acme screw jacks with a capacity up to 350 tons and everything in between. Learn about our machine and ball screw jacks.
