Features

In our new "CSD series" Harmonic Drive®, which inherit the excellent performance characteristics of the "CSF series", weight and configuration compactness have been taken to new extremes.
"CSD series" Harmonic Drive® are offered in a series of 7 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
