Ringfeder Power Transmission 4061-062SR Disc Coupling

Ringfeder Power Transmission 4061-062SR Disc Coupling is a two-hub, keyless locking rigid coupling that uses RFN 4061 shrink discs to clamp the hubs onto 62 mm bore shafts, enabling backlash-free torque transmission through a secure frictional interface. It has a 62 mm bore on both sides, an outside diameter of 110 mm, and an overall length of 34.50 mm, with 12 locking screws on the shrink-disc assembly to provide uniform clamping and consistent hub-to-shaft contact. The assembly is steel, weighs about 2.9 kg, and reports a hub surface pressure of 419 N/mm and a transmissible axial force of 133 kN, while the overall torque capacity depends on the selected RFN 4061 disc pack. Designed for rigid shaft connections in power-transmission systems such as servo drives and automated machinery, the 4061-062SR is part of Ringfeder’s RFN 4061 family and offers a compact, backlash-free option when precise alignment and robust clamping are required.
