The RINGSPANN REK DGZ 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 radial, angular and axial displacement, reducing vibration and protecting the equipment. It is used in pumps, gearboxes, fans and machinery in general. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, with technical advice to choose the right model.
The REK DGZ series designation is read step by step: REK identifies the jaw coupling family; the four-digit number that follows —as in REK 0028 DGZ or REK 0042 DGZ— indicates the coupling size, which correlates with the maximum allowable shaft diameter and the torque capacity; the suffix DGZ indicates a construction variant within the series, normally associated with the type of elastomer or the jaw configuration. The examples REK 0048 DGZ, REK 0055 DGZ, REK 0060 DGZ, REK 0065 DGZ, REK 0075 DGZ and REK 0080 DGZ show the progression of available sizes.
These couplings are used in Argentine industries such as food, chemical, petrochemical, cement and water treatment. They are present in centrifugal pumps, gearboxes, fans, compressors, conveyor belts and mixers. Their ability to absorb misalignment and dampen vibration makes them suitable for equipment where extreme alignment precision is not required, but reliability and ease of maintenance are.
To select a REK DGZ coupling, take into account the nominal and maximum torque of the drive, the rotation speed, the shaft diameters and the type of load. The intermediate elastomer defines the torsional stiffness and the damping capacity; choose the compound according to temperature and environment. During assembly, check shaft alignment with straightedges or a dial indicator, respect the recommended axial clearance and secure the hubs with the corresponding set screws or keys. No lubrication is required in these couplings, but periodic inspection of the elastomer is.
As for equivalents, RINGSPANN REK DGZ jaw couplings can be interchanged with other brands that follow the same standard for dimensions and capacities, such as the L, AL or similar series. Interchangeability depends on the shaft diameter, the torque and the mounting dimensions. Always check the drawings and tolerances before replacing one coupling with another from a different manufacturer. MR Accesorios Industriales can advise you with the technical comparison.

Frequently Asked Questions
- What does the REK DGZ designation mean?
- REK identifies the jaw coupling series; the four-digit number indicates the size and torque capacity; DGZ indicates the elastomer or configuration variant. Send the full part number to identify the exact replacement.
- Does this coupling need lubrication?
- No, jaw couplings with an elastomer do not require lubrication. Only periodic inspection of the elastic element is recommended to detect wear or hardening, and replace it if necessary.
- Can I replace a coupling from another brand with a RINGSPANN REK DGZ?
- Yes, as long as the mounting dimensions, shaft diameter and torque capacity match. It is important to check the tolerances and the type of elastomer. Consult us with your equipment data to validate the equivalence.
