– It has a clamping length of 175mm.
– Maximum torque T: 562,000 Nm.

– Ringfeder RfN 4023 belongs to the heavy-duty category for high torque and bending moments.
– The highest reliability of the shrink disc is a modern method to create a mechanical flexible coupling.
– Easy adjustment, installation, and disassembly, with minimal susceptibility to dirt.
– It consists of one or two thrust rings with tapered bores and an inner conical ring.
– 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.
– Positioned around the center, it only has one transmission interface, providing unique advantages such as offering concentric connection capability and suitable balance for high-speed applications. Shrink couplings require complex calculations, tight machining tolerances, and good surface finishes. They also require significant effort during assembly and disassembly.
