Worm gearboxes contain a worm/screw gear on the input shaft, and a mating worm/spur gear on the output shaft. Worm gearboxes also change the drive direction by 90°. Our gearboxes utilize C-face mounting interfaces for C-face motors.

Aluminum gearboxes feature hollow-shaft outputs (all the way through from one side to the other). For the aluminum gearboxes we also offer optional single and double output shafts, output flanges, torque arms, and output covers.

The highest quality materials are tested, certified, and used in the manufacturing process. Strict adherence to and compliance with the toughest international testing standards and manufacturing procedures assure you the highest quality products.
