Features

Complete Freewheels FBE … XG with flexible shaft coupling are sprag freewheels with sprag lift-off X and grease-lubricated ball bearings for coupling two aligned shafts.

The sprag lift-off X ensures wear-free freewheeling operation when the inner ring rotates at high speed.

The freewheels FBE … XG are used as:

➧Overrunning Clutches

for applications with high speed freewheeling operation.

Nominal torques up to 7 500 Nm.

Bores up to 95 mm. Many standard bores are available.

Application example

Complete Freewheel FBE 72 DXG with shaft coupling as overrunning clutch in the drive system of a fan. The freewheel is positioned between the main motor and the auxiliary drive. When the system is driven by the main motor, the auxiliary drive is automatically disengaged by the freewheel. Due to the high speed of the main motor, the type with sprag lift-off X is used; the sprags work in freewheeling operation without contact and hence are wear-free.

The maximum transmissible torque is 2 times the specified nominal torque. See page 14 for determination of selection torque.
