Cycloidal reducers

CR Series

Cycloidal reducers are a class of gearboxes characterized by their small size, high number of achievable reduction ratios, and high load capacity. Starting from a minimum ratio of 1:6 up to a ratio of 1:72, they are available in a single stage and their axial compactness is a distinctive feature.

Thanks to these characteristics, cycloidal gearboxes are widely used in the fields of robotics, machine tools, assembly/packaging machines, and positioning applications. The possible configurations are:

  • HH (hole-hole): hollow input and output for quick and slow shaft insertion;

  • HS (hole-shaft): hollow motor input and shaft output;

  • HF (hole-flange): hollow motor input and flange output that can be used as a positioner.

The accuracy is 3 arcmin.
