Worm Drive Gearboxes for High Torque Applications
Our worm gearboxes are greased forever and feature solid aluminum housings and ball bearings on input and output. If you’re uncertain which gear reduction box is best suited to your application, look at our Buyer’s Guidebook to see ten essential points to consider whenever choosing a gearbox. Another useful reference, Inertia and the Use of Inertia Numbers, offers a formulation for coping with inertia in worm gear selection.
