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