The maximum transmissible torque is 2 times the specified nominal torque.
** Z = Number of fastening holes for screws G (DIN EN ISO 4762) on pitch circle T.
Application example
Complete Freewheel FGR 50 R A1A2, used in a hydraulically released, spring actuated multidisc 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.
 
Mounting
Basic Freewheel, flange, cover, seals and screws are supplied loose. These must be assembled by the customer with regard to the required freewheeling direction into the Complete Freewheel. Prior to commissioning, the freewheel must be filled with oil of the specified quality. Upon request, assembled Complete Freewheels already oil-filled can be supplied. With Complete Freewheels FGR R A1A2, the customer attachment part is centered on the external diameter D and bolted on to the face via flange A1.
With Complete Freewheels FGR R A2A7, the customer attachment part is centered on the
pilot diameter R and bolted on to the face via flange A7. Hence, Complete Freewheels FGR
SF A2A7 are particularly suitable for attaching smaller and narrower parts (sprockets, gear
wheels etc.). The tolerance of the shaft must be ISO h6 or j6 and the tolerance of the pilot diameter D or R of the attachment part must be ISO H7 or J7.
