Worm Drive Gearboxes for High Torque Applications
Our worm gearboxes are greased for life and feature solid aluminium housings and ball bearings on input and output. If you’re uncertain which gear reduction container is most effective to your application, look at our Buyer’s Guide to see ten important points to consider when choosing a gearbox. Another useful reference, Inertia and the usage of Inertia Figures, offers a method for dealing with inertia in worm equipment selection.
