HarmonicDrive

In our new "CSD series" Harmonic Drives, which inherit the excellent performance characteristics of the "CSF series", weight and configuration compactness have been taken to new extremes. "CSD series" Harmonic Drives are offered in a series of five different component types, opening up new possibilities for motion control speed reducers.

Thickness has been reduced to 1/2 that of the conventional CSF series;
Torque capacity is 70% of the CSF series;
Torsional rigidity is 80 to 90% of the CSF series;
The series is compatible with a hollow-shaft construction.
