Features

Having evolved further, our component type Harmonic Drive® have re-emerged in a more compact and easier-to-install configuration.
Component type CSF series Harmonic Drive® have been developed to meet the needs of the industry as they concern space saving, cost efficiency and other performance characteristics at a time when demand for such features are increasing in tandem with the accelerated pace of technological innovation. The CSF series Harmonic Drive® offered here can be directly integrated into your machinery/equipment. With the addition of a 1/30 reduction ratio series, our Harmonic Drive® have made their debut in an even richer line-up so you can select the unit that is most suitable for your needs.

• Compact and simple configuration
• High torque capacity
• High rigidity
• Non backlash
• High positional accuracy and high rotational accuracy
• High efficiency
• Smoothness of operation
• Coaxial input and output
