SC Series Wrap Spring Clutches
Spring Clutch Family:
SC series spring clutches are available in 3 styles:
SR Single Revolution
Overrunning/one way (OR) – This clutch continually drives the load. The load is allowed to overrun the input, should its speed exceed input speed. In the reverse direction the unit acts as a one-way clutch.
Start/Coast (SS) – The start/coast clutch is engaged until the collar which contains the spring tang is stopped. Once it is stopped, the load is disengaged and coasts to a stop.
Single Revolution (SR) – Attaching one end of the spring to the output hub results in a single revolution clutch. The load is stopped through the spring to the collar. Precise non accumulative error single revolution cycling is achieved. Braking torque equals 10% of the maximum torque rating.
The SC family of clutches is designed to replace competitors' clutches. Special bore sizes and hub configurations are available upon request.
• Clutches can be supplied with hub or shaft inputs
• Multiple stop collars
