FGRN R A5A6 series

Product catalog summary

Application Example: The document describes the use of a Complete Freewheel FGRN 45 R as an overrunning clutch on the shaft end of a mobile fan. In normal operation, the fan is driven by a diesel motor via a V-belt drive, with the freewheel in driving operation. When the motor is turned off, the freewheel disengages the rotating flywheel mass of the fan from the drive, allowing the inner ring to overrun the stationary outer ring, thus operating in freewheeling mode.

Applications: The Complete Freewheels FGRN … R A5A6 can be used as a Backstop, Overrunning Clutch, or Indexing Freewheel. They are sealed roller freewheels with ball bearings and are oil lubricated.

Specifications: The freewheels have nominal torques up to 6,800 Nm and bores up to 80 mm. The document provides a detailed table of dimensions and specifications for various sizes, including bore diameter, nominal torque, and maximum speed for both inner and outer ring freewheeling.

Assembly and Ordering: Basic Freewheels, covers, seals, and screws are supplied loose and must be assembled by the customer. The freewheel must be filled with oil of specified quality before commissioning. Assembled, oil-filled Complete Freewheels can be supplied upon request. The customer must provide the key for the keyway connection with the outer ring. Tolerances for the shaft and pilot diameter are specified as ISO h6 or j6 and ISO H7 or J7, respectively.

Ordering Example: For ordering a Freewheel size FGRN 60, standard type with flange A5 and cover A6, specify the freewheeling direction of the inner ring as either counterclockwise or clockwise free.

Additional Information: Freewheels with bore diameters highlighted in blue in the table are available with short delivery times. The maximum transmissible torque is twice the specified nominal torque. Keyway specifications follow DIN 6885, page 1, with a tolerance of keyway width JS10.
