Disengaging
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.
Engaging
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
Type DC BWC BWX is a sprag type freewheel cage without inner or outer races. It must be installed in a design providing races, bearing support for axial and radial loads, lubrication and sealing.
