The GUMMI A-80 flexible coupling is a power transmission component that connects two shafts and absorbs misalignment, vibration and torsional shock. Its rubber flexible center allows smooth, quiet operation, protecting motors and driven machines. It is used in a wide variety of industrial applications where torque must be transmitted with a certain flexibility. MR Accesorios Industriales sells this model as part of its GUMMI coupling line.
This GUMMI A-80 coupling belongs to the Type A series and is configured with two normal hubs (CN). It has a nominal torque of 1550 Nm, a maximum bore of 75 mm and a pilot hole of 30 mm. The flexible center diameter is 302 mm, the overall length reaches 250 mm and its weight is 24.9 kg. These characteristics position it as a robust option for demanding power transmissions.
Typical applications for this coupling include centrifugal pumps, fans, compressors, conveyor belts and machine tools. Its rubber flexible center design compensates for angular and radial misalignment, reducing vibration and noise in the transmission. It is commonly found in equipment where bearings and gears must be protected from torque peaks.
To correctly select an A-80 coupling, take into account the nominal torque required by the application, the diameter of the shafts to be connected and the environmental conditions. The maximum bore of 75 mm and the pilot hole of 30 mm allow the hubs to be machined to match the shaft. It is important to verify alignment during assembly and use the appropriate fastening elements to avoid parasitic stresses.

Frequently Asked Questions
- What does it mean that the coupling has two normal hubs?
- The CN configuration indicates that both hubs are of standard design, without special machining. This allows the coupling to be mounted on shafts with keyway and conventional fastening, making installation easier in most industrial applications.
- Can I replace a coupling from another brand with this GUMMI A-80?
- Yes, as long as the critical dimensions are verified: nominal torque, shaft diameters, overall length and distance between ends. Message us on WhatsApp with the data of the original coupling and we will advise you to find the right equivalent.
- What maintenance does this flexible coupling require?
- It is recommended to periodically inspect the condition of the rubber flexible center, checking that it does not show cracks, permanent deformation or excessive wear. It is also important to check shaft alignment and the tightening of the fastening elements.
