Worm Drive Gearboxes for High Torque Applications
Our worm gearboxes are greased for life and feature solid light weight aluminum housings and ball bearings on input and output. If you’re uncertain which gear reduction box is best suited to your application, watch our Buyer’s Guide to see ten essential points to consider when choosing a gearbox. Another important reference, Inertia and the Use of Inertia Figures, offers a formula for coping with inertia in worm gear selection.
