Worm Drive Gearboxes for High Torque Applications
Our worm gearboxes are greased for life and feature solid aluminum housings and ball bearings on input and output. If you’re not sure which gear reduction container is most effective to your application, watch our Buyer’s Guidebook to see ten important points to consider whenever choosing a gearbox. Another valuable small worm gearbox reference, Inertia and the Use of Inertia Figures, offers a formula for coping with inertia in worm gear selection.
