Features
Cage Freewheels BWX are sprag freewheels to be installed between customer-supplied inner and outer rings.
The freewheels BWX are used as:
➧ Backstops
➧ Overrunning Clutches
➧ Indexing Freewheels
Nominal torques up to 4 900 Nm.
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.

1 With this Freewheel Sizethe centering flange of the inner cage is on the right hand side!
2 Tolerance of the inner ring race diameter may be increased by ±0,013 mm!
The theoretical nominal torque applies only for ideal concentricity between the inner and outer ring.
The maximum transmissible torque is 2 times the specified nominal torque. See page 14 for determination of selection torque.
Mounting Example
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.

Pictures
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, the- reby 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 du- ring rapid acceleration and deceleration of the outer ring (e.g. in indexing freewheels).
