Application as Backstop ► Overrunning Clutch ► Indexing Freewheel Features Complete Freewheels FGR ... R A1A2 with mounting flange are sealed roller freewheels with ball bearings. They are oil lubricated. Nominal torques up to 68 000 Nm. Bores up to 150 mm. Application example Complete Freewheel FGR 50 R A1A2, used in a hydraulically released, spring actuated multidisk brake for winch drives. When the load is lifted, the multiple-disk brake is closed and the inner ring is freewheeling. At a standstill, the freewheel functions as a backstop. The load is held by the brake and the locked freewheel. When lowering, the brake is released with control and the load is lowered via the locked freewheel.By using the freewheel, the hydraulic control could be designed in an simpler and more cost-effective manner.
