Worm Drive Gearboxes for High Torque Applications
Our worm gearboxes are greased forever and feature solid aluminium housings and ball bearings on input and output. If you’re not sure which gear reduction box is best suited to your application, look at our Buyer’s Guidebook to see ten important points to consider when choosing a gearbox. Another precious reference, Inertia and the use of Inertia Figures, offers a method for coping with inertia in worm gear selection.
