Why Choose a Varvel 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 the Varvel 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 the Varvel design to meet your needs for right angle power transmission.
