Worm gearboxes (worm gear speed reducers) drive a load at a reduced fixed ratio of the motor speed, utilizing a worm pinion (or screw) that is coupled with a round toothed gear (or worm wheel. Output torque is increased by that same ratio, while horsepower is unchanged (less efficiency losses).

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 heavy-duty, right-angle worm gear reducers offer exceptional value for applications where food-grade or corrosion resistant equipment is required. The stainless steel housings provide protection from close-range high pressure, high temperature spray downs.
Cast iron worm gearboxes are built tough with rugged cast iron housings that can withstand harsh industrial environments and provide a long trouble-free service life.
Aluminum worm gearboxes are lower-cost alternatives that feature a lightweight construction, and hollow-shaft outputs (all the way through from one side to the other). They are ideal for light-duty applications that have a less frequent run rate or can justify a shorter service life.
