One-Way Clutches
Since they transfer torque in one direction and spin freely in the other, these clutches are useful in applications where you don’t want motion to reverse, such as in backstopping, indexing, and overrunning. For example, they can be used to prevent a conveyor from reversing direction.
When choosing a clutch, consider how much torque you need to transfer. You should also consider how the clutch will attach to your mounted component.
Roller Engagement—Knurled Hub
 |
Roller clutches are best for low- to medium-torque transfer in overrunning and indexing applications.
Clutches with a knurled hub can be press fit into the bore of your component.
Through Shaft—Through-shaft clutches regulate torque transmission between an input shaft and a mounted component.
Set-Screw Shaft Mount—Clutches that mount to shafts with set screws bite into your shaft when tightened to hold it.
