Worm Drive Gearboxes for High Torque Applications
Our worm gearboxes are greased forever and feature solid aluminium housings and ball bearings on insight and result. If you’re not sure which gear reduction box is best suited to your application, view our Buyer’s Guide to see ten essential points to consider when choosing a gearbox. Another important reference, Inertia and the usage of Inertia Numbers, offers a method for dealing with inertia in worm gear selection.
