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