2. Characteristics of Ringfeder RfN 4071 SST:
– Shrink Disc RfN 4071 SST is manufactured by Ringfeder/Germany.
– Inner diameter of the hollow shaft: 850 mm.
– Clamping length: 119 mm.
– Shaft diameter: 170 mm – 420 mm.
– Maximum torque: 1.45E6 Nm.
– The Ringfeder RfN 4071 SST is a modern method for creating mechanical shrink fits. It consists of one or two thrust rings with tapered bores and an inner ring with a tapered outside diameter. By tightening the locking screws, the thrust rings are pulled together, compressing the inner ring and exerting pressure outward from the center to clamp it onto the shaft.
– The shrink disc device is arranged around the center, with only one transmission interface, providing unique advantages such as concentric connection capability and suitable balance for high-speed applications.

The shrink disc Ringfeder RfN 4071 SST is primarily used in cases where there are thin-walled or hollow shafts with limited ductility, typically made from materials such as gray cast iron or aluminum. They minimize surface stress in the connected components, providing a reliable and efficient connection method in such applications.
