Harmonic Drive®, which is made up of just three basic components, makes accurate motion control possible with its unique mechanism. Compared with conventional products, the thickness of CSF series Harmonic Drive® has been reduced by 1/2.

In addition, the CSG series is now on the market, offering further improvements in performance in comparison with its CSF series counterparts. One further addition is the SHF series, which features a large-caliber hollow-shaft construction. Our family of Harmonic Drive® is thus evolving with the times.

The differential unit FD series is an extremely compact differential unit that allows you to fine-tune the phase and timing during operation by applying the unique operating principle of Harmonic Drive®.
The FD series consist of four parts like the pancake-type component unit.
The unit type is cased so that the gear and pulley for transmission can be directly installed in it.
