The ERH series is a compact, robust cycloidal reducer designed for servo applications. This product features high reduction ratios in a compact form factor. Its key advantage is exceptional shock load capacity, which eliminates the need to oversize the reducer for that requirement. The dual pin housing of the ERH cycloidal provides the ability to adjust one wheel against the other, allowing us to reduce the output shaft backlash to less than 6 arc-minutes. Rolling contact contributes to minimal friction and high efficiency. Torque transmission elements experience compression—they do not shear. The long output shaft bearing span provides solid overhung load capability.
