    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.

    Torque Arms

    Sprag clutches handle higher torque than roller clutches because they have more contact points. This makes them best for backstopping applications.
    Clutches with a flush hub have a precision ground outer race, so they can be press fit directly into a component and positioned anywhere along the length of your shaft. They also have mounting holes on their face you can use to secure your component or an anti-rotation device, such as a torque arm, for a different backstopping setup.
    Through Shaft—Through-shaft clutches regulate torque transmission between an input shaft and a mounted component.
    Slip-Fit Shaft Mount—Clutches that mount to shafts with a slip fit must be secured with a shaft collar or in some other way that prevents them from moving along the length of your shaft.
    Covers—Covers protect you from rotating equipment when the clutch is mounted to the end of the shaft.
    Torque Arms—Clutch torque arms work as an anchor for clutches in backstopping applications. Mount to the outer race of your clutch and a stationary piece of equipment.
