1. Outer race 2. Cage 3. Sprag 4. Spring 5. Inner race High overrunning speed High torque capacity High eccentricity tolerances Accepts any lubricant

Sprags in this design, are fitted into a cage connected to the overrunning member.
The sprag configuration is such that its centre of gravity is offset to its rotation axis.

Centrifugal force creates a lift off moment against an engaging spring. When the centrifugal force moment is greater than that of the spring, the sprag tilts over to a contact free position.

The sprag height and its active profile length allow this type of freewheel to accept significant eccentricity tolerances and to work with all the current lubricants used in power transmissions.
