Aluminum Worm Gearboxes (NEMA Input) and Accessories

Aluminum worm gearboxes (speed reducers) with NEMA inputs drive loads at a reduced fixed ratio of motor speed, with lightweight corrosion-resistant housings. Output torque is increased by that same ratio; horsepower is unchanged (less efficiency losses).

Aluminum Worm Gearboxes (NEMA Input)

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 medium-duty aluminum worm gearboxes with NEMA input faces are cost-effective options, where a heavy-duty gearbox isn't required. These are designed specifically to mate with NEMA C-face and TC-face motors.

Aluminum Worm Gearboxes
(NEMA Input)

Aluminum worm gearboxes with NEMA input faces are low-cost and lightweight with hollow-shaft outputs that extend all the way through from one side to the other. They feature a hardened worm shaft for increased durability and are ideal for medium-duty applications that have a less frequent run rate or can justify a shorter service life.
