Application example
Complete Freewheel BA 52 SXG as a backstop on a radial fan. The backstop prevents a reverse rotation of the fan shaft from air flow or from an incorrectly polarized drive motor. By pulling out the holding pin in the lever arm, the shaft can be turned in both directions in order to carry out maintenance work. With the high shaft speed, the type with sprag lift-off X is used; the sprags work in freewheeling operation without contact and hence are wear-free.

Mounting
The backdriving torque is supported by the lever arm with holding pin. The holding pin engages in a slot or bore in the frame of the machine. It must have 0,5 to 2 mm play in the axial
and radial directions. If the holding pin is removed, the shaft can be turned in both directions.
The tolerance of the shaft must be ISO h6 or j6. The freewheels BC XG are supplied ready for installation. In the case of freewheels BA XG, the inner ring must be secured axially with a retainer plate.

Example for ordering
Freewheel size BC 45 type with sprag lift-off X, grease lubrication and 65 mm bore:
 BC 45 SXG, d = 65 mm
When ordering, please also specify the freewheeling direction of the inner ring when
viewed in direction X:
 counterclockwise free or
 clockwise free
