Cyclo® Overhead Drive

The inline, vertical drive utilizes Cyclo's unique epicycloidal design and has advantages superior to speed reducers using common involute tooth gears. The Cyclo components operate in compression, not in shear. Unlike gear teeth with limited contact points, a Cyclo has two-thirds of its reduction components in contact at all times. This design enables Cyclo speed reducers and gearmotors to withstand shock loads exceeding 500% of their ratings, and provide exceptional performance, reliability and long life in the most severe applications.
