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 result. 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 when choosing a gearbox. Another precious reference, Inertia and the utilization of Inertia Statistics, offers a method for dealing with inertia in worm equipment selection.
