Flexible workhorses with multiple connection options

Flexible workhorses with multiple connection options
Absolute positioning accuracy, high temperature resistance and flexible applications are the compelling features of Ringfeder Power Transmission's RING-flex multiple-disc couplings. These torsion-proof multiple-disc couplings offer backlash-free and precise transmission of torques, while compensating for axial, lateral and angular misalignments.

When developing the RING-flex multiple-disc couplings, Ringfeder Power Transmission says it not only attached high importance to typical parameters such as torsional stiffness and high true-running accuracy, but also to compact dimensions and multiple connection options. Depending on customer requirements, the hubs can be attached to the shafts by means of keys, clamping hubs, shrink discs or locking assemblies. 

All models are available as single or double Cardan types. For double Cardan couplings, in addition to the standard length, Ringfeder Power Transmission also offers a version with a short spacer. For special customer requirements, customised solutions with a freely determinable spacer length are also possible. 

RING-flex couplings particularly prove their strengths in drives where the positioning accuracy in both directions is of high importance, for example in machines with frequent start/stop or reverse operation. Small manufacturing tolerances ensure a high level of true-running accuracy, enabling the use of the couplings even at high speeds and with irregular operating torques.

The couplings have proven successful even under harsh conditions thanks to their high power performance and temperature resistance. Nominal torques of up to 260,000Nm and shaft diameters of up to 250 millimetres are available.
