The RINGSPANN WKE-RF coupling is a zero-backlash elastomeric coupling that transmits torque between shafts with high angular precision. It is used in applications where positioning accuracy is critical, such as servo motors, ball screws and numerical control systems. Its design compensates for misalignment while maintaining torsional rigidity, preventing cumulative errors in motion. MR Accesorios Industriales supplies this line in Argentina.
The WKE-RF designation identifies RINGSPANN's series of zero-backlash elastomeric couplings. The RF suffix indicates the version with a precision elastic element. Available sizes range from 19 to 48, and each number defines the mounting dimensions and torque capacity. In the examples, WKE-RF / size 19 is the most compact, while WKE-RF / size 48 is the one with the largest diameter and torque. To select the right one, you need to cross-check the nominal torque, maximum speed and permissible shaft diameter.
These couplings are used in machine tools, machining centers, measuring equipment, automation and robotics. In Argentina, they are common in the metalworking, food and packaging industries, where synchronism between shafts is required. They are also used in test benches and dynamic positioning systems. Their ability to work without backlash makes them suitable for frequent reversal cycles and repetitive starts and stops.
To choose a WKE-RF, take into account the working torque, rotation speed and permissible misalignment. The elastomeric element compensates for angular, radial and axial misalignment, but it must not be forced beyond its limits. Installation requires careful alignment and uniform tightening of the screws. Lubrication is not necessary for this type of coupling, although it is advisable to periodically check the condition of the elastomer. Installation with backlash or misalignment accelerates wear.
RINGSPANN WKE-RF couplings can be interchanged with other brands of zero-backlash elastomeric couplings, as long as the flange dimensions, shaft diameter and nominal torque match. There is no universal equivalence table: each manufacturer defines its own codes. Therefore, to replace an existing coupling, the safest approach is to send the complete code and the shaft dimensions. MR Accesorios Industriales can guide you through that comparison.
If you need a WKE-RF coupling for your application, write to us on WhatsApp with the size or the code shown on the nameplate. We will reply shortly with the technical information and the quote. MR Accesorios Industriales, Buenos Aires, Argentina.

Frequently Asked Questions
- What does it mean that the WKE-RF coupling is zero-backlash?
- It means there is no torsional play between the shafts. This allows motion to be transmitted accurately, without delays or positioning errors. It is key in servo mechanisms and screws where every fraction of a turn counts.
- How do I choose the correct WKE-RF coupling size?
- You need to consider the nominal torque, maximum speed and diameter of the shafts to be joined. The size is chosen based on the torque it must transmit and the mounting dimensions. Send me that data and I will advise you.
- Can a coupling from another brand be replaced by a RINGSPANN WKE-RF?
- Yes, if the flange dimensions, shaft diameter and torque match. There is no automatic equivalence between brands. Send the original coupling code and the dimensions to verify interchangeability.
