Cast Iron Worm Gearboxes and Accessories

Cast iron worm gearboxes (speed reducers) drive a load at a reduced ratio of the motor speed, with rugged housings to withstand industrial environments. Output torque is increased by that same ratio, while horsepower is unchanged (less efficiency losses).

Cast Iron Worm Gearboxes

Worm gearboxes (speed reducers) are mechanical power transmission components that utilize a worm pinion (or screw) that is coupled with a round toothed gear (or worm wheel). As a motor turns the worm pinion, its spirals will cause the worm wheel to turn and drive a load at a reduced ratio of the supplied motor speed. Worm gearboxes provide reliable speed reduction and increased torque with virtually no loss in horsepower.

These cast iron models are the most popular worm gearbox variant with the widest selection of sizes, gear ratios, and shaft input styles. They deliver heavy-duty performance in a cost effective package.
