Standard Industrial Worm Speed Reducers
Our aluminum worm gearboxes are industrial gear reducers that provide highly reliable power transmission for general-purpose applications. Our worm gear reducers are designed, manufactured, and assembled in Italy’s famous gear production region. These aluminum worm gearboxes offer cost-effective operation and superior performance over similar-looking products. See specs for custom worm gearbox design options.

Why Choose a Speed Reducer?
There are many worm speed reducers in the market, from the traditional cast iron models made for years in America, to the new aluminum models coming from Asia. But none offer the design features, performance, and value that come with a worm gear reducer.
European engineering and workmanship assure highly reliable performance in a variety of applications. Ground gearing and precise assembly provide high efficiency operation while oversized bearings accommodate high radial and axial loads. And the single piece aluminum housing is light yet extremely strong.
All these benefits come with a competitive price that adds exceptional value and design versatility to your machine designs.
Don’t be confused by other gearboxes that look the same. It’s what’s inside that counts. You can rely on this design to meet your needs for right angle power transmission.
