RINGSPANN REK 0055 DHO is a coupling reference, within Power transmission. Request a quote for REK 0055 DHO via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.
The RINGSPANN REK DHO series jaw coupling is a power transmission component that connects two shafts and transmits torque while absorbing misalignment. Its jaw design with an intermediate elastomer compensates for small angular, radial and axial displacements, reducing vibration and protecting equipment. MR Accesorios Industriales supplies this line in Buenos Aires, Argentina, with technical support to select the right model for your application.
The REK DHO series designation is read step by step: REK identifies the jaw coupling family; the four-digit number that follows —as in REK 0048 DHO or REK 0100 DHO— indicates the coupling size within the series; and the DHO suffix distinguishes the design variant or the elastomer type. The examples REK 0055 DHO, REK 0065 DHO and REK 0090 DHO show how the code changes with size. To select one, consider torque, speed and shaft diameter.
These couplings are used in industries such as food, chemical, petrochemical, cement and materials handling. In Argentina, they are commonly found in centrifugal pumps, fans, compressors, conveyor belts and machine tools. Their ability to absorb misalignment and damp vibration makes them suitable for equipment with frequent starts or variable loads. MR Accesorios Industriales offers them for replacement and new projects in plants across the country.
To correctly select a jaw coupling, take into account nominal and maximum torque, rotational speed, shaft diameter and fit type, and environmental conditions. The elastomer can be NBR, PU or EPDM depending on temperature and chemical resistance. Installation requires aligning the shafts within the permissible tolerances; excessive misalignment accelerates wear of the elastic element. Lubrication is not required for this type of coupling, which simplifies maintenance.
As for equivalents, RINGSPANN REK DHO jaw couplings can be interchanged with other brands that use the same jaw and elastomer concept, but always verify the critical dimensions: outer diameter, length, bore diameter and keyway type. A similar code is not enough; drawings must be compared. If you need to replace an existing coupling, send us the full code or the shaft dimensions and we will help you find the right option.
To request a quote for a RINGSPANN REK DHO jaw coupling, write to us on WhatsApp with the exact code shown on the nameplate or drawing. If you do not have it, send us the equipment data: power, RPM, shaft diameters and load type. At MR Accesorios Industriales we reply promptly with the alternative that best suits your needs.

Frequently Asked Questions
- What does the DHO suffix mean in RINGSPANN REK couplings?
- The DHO suffix identifies a specific variant within the REK series, generally associated with the elastomer type or hub configuration. To confirm the exact application, it is best to check with the full code and the service conditions.
- How do I select the correct jaw coupling size?
- You need to know the nominal and maximum torque, the RPM, the shaft diameters and the working environment. With that data, the size that guarantees a suitable service factor is selected. If you have doubts, send us the data and we will advise you.
- Do jaw couplings need lubrication?
- No, this type of coupling works with an intermediate elastomer that does not require lubrication. You only need to periodically check the condition of the elastic element and the shaft alignment to ensure a long service life.
