Worm Drive Gearboxes for High Torque Applications
Our worm gearboxes are greased forever and feature solid aluminum housings and ball bearings on insight and output. If you’re uncertain which gear reduction container is most effective to your application, look at our Buyer’s Guidebook to see ten essential points to consider whenever choosing a gearbox. Another valuable reference, Inertia and the Use of Inertia Figures, offers a formula for dealing with inertia in worm gear selection.
