Clutch-related products

Introducing a clutch that transmits rotation in one direction only and freewheels in the opposite direction!

We would like to introduce the "clutch-related products" that we handle. They are composed of three categories: one-way clutches, torque diodes, and mechanical clutch units. The one-way clutch is characterized by stable free rotation and a small phase lag, eliminating the need for bearings for radial load. The mechanical clutch unit combines a mechanical roller clutch with an electromagnet, achieving both higher torque transmission capability and ease of electrical control. 【Features】 <One-Way Clutch> ■ Stable free rotation ■ No need for axial or rotational direction fixing devices ■ No need for bearings for radial load ■ Small phase lag (average value of 3° or less) <One-Way Clutch Unit> ■ Compact design made possible by unitization ■ Greater freedom in selecting the shaft to be used *For more details, please download the PDF or feel free to contact us.
