When the outer ring is rotating the centrifugal force causes the sprags to lift off from the inner

race. This reduces wear during freewheeling operation.



When the outer ring is rotating the centrifugal force presses the sprags against the inner ring.

This enhances the ability of the sprags to engage immediately when torque is applied.


Drag strips

To reduce wear during freewheeling operation between sprags and the inner race, drag strips

made from wear-resistant beryllium copper alloy are attached to the inner cage. This results in increased friction between inner cage and inner race. This counteracts individual sprag activation during freewheeling operation, thereby greatly reducing sprag pressure on the inner race.


Brake clips

Some freewheel sizes are available with brake clips fitted on the outer cage to prevent further

automatic rotation of the Cage Freewheel during rapid acceleration and deceleration of



The lateral guidance of the Cage Freewheels can be effected either by a shoulder on the

outer ring or by guard rings or guard discs which are fixed in the outer ring. There must be

no undercuts, recesses, shoulders or chamfers, or any eccentricity whatsoever, over dimension „B“. For ease of assembly we recommend that the inner and outer races be chamfered at an angle of 15 degrees for a leghts of 3 mm.
