Product Features

Cycloidal Speed Reduction Technology
Quiet, efficient and reliable operation with high torque density and compact in size
Break-Resistant Teeth
The "cycloidal disc" has a unique and smooth curve, which together with its smooth rolling contact, prevents tooth breakage, resulting in a durable product with a long product life.
We manufacture a wide range of reduction ratios in a single reduction, from 2.5 to 119. We can easily configure double and triple reduction types by simply layering the reducer mechanisms.
Because of its flat Cyclo disc arrangement, it is very compact, even at high reduction rates.
Modular Design
Interchangeable cast iron housing in foot, flange or face mounting configurations.
Broad Variation
Choose the product that best fits your needs from a wide selection, including capacities of 0.1 - 132 kW, reduction ratios of 2.5 - 658503, as well as outdoor and explosion-proof motor types.
Superior Steel Components
Internal components manufactured from hardened, vacuum-degassed, bearing grade steel provide minimal vibration, low noise, low backlash and extended operational life.

Break-Resistant Teeth

Unlike a regular involute tooth-gear, the "cycloidal disc," which is the gear for the Cyclo® Reducer, features a distinctively smooth curve.
A unique circular-arc tooth profile is also used for the internal gear. The smooth rolling contact that prevents tooth breakage results in a durable gearbox with a long service life. (Some low reduction ratio models use helical gears and planetary gears.)
