The GUMMI A-50 flexible coupling is a power transmission component that connects two shafts and dampens vibrations and torsional shocks. Its elastic rubber center absorbs slight misalignments and reduces noise transmission. It is used in pumps, fans, compressors and conveyors. MR Accesorios Industriales sells this model from the Type A series, with two standard hubs, for replacements and new projects.
The A-50 is a coupling from the GUMMI Type A series, with a two standard hubs (CN) configuration. Its elastic center has a diameter of 167 mm and the total length of the assembly is 140 mm. The nominal torque is 420 Nm and the maximum bore per hub is 46 mm. The 15 mm pilot bore allows machining the final diameter according to the shaft. The weight of the coupling is 5.32 kg. These values define its capacity to transmit power with damping.
This coupling is used in drives where vibration and small misalignments must be absorbed. It is common in centrifugal pumps, fans, screw compressors, conveyors and machine tools. It is also used in mining, cement and treatment plant equipment. Its rubber center reduces the transmission of impulsive loads and extends the life of the connected bearings and gears.
To select the A-50, verify that the application torque does not exceed 420 Nm and that the shaft diameter does not exceed 46 mm. The 15 mm pilot bore must be machined to the required diameter, respecting the tolerance and keyway. Alignment between shafts must be careful to avoid stresses on the elastomer. In applications with reversing rotation or pulsating loads, consider a service factor.
If you need a coupling with another configuration, such as hubs with brake or flange, or a higher capacity model, we can offer alternatives within the GUMMI line. We can also advise you on replacement with a coupling from another brand with equivalent performance. For that, write to us via WhatsApp with the code A-50 or your shaft dimensions and the required torque.

Frequently Asked Questions
- What does it mean that the A-50 coupling has a CN configuration?
- CN indicates two standard hubs, meaning both hubs are identical and are mounted on the shafts. The elastic rubber center is located between them and transmits torque while dampening vibrations. It is the standard configuration for most applications.
- Can I machine the pilot bore to a larger diameter?
- Yes, the 15 mm pilot bore allows machining the hub up to the maximum bore of 46 mm. The workshop must perform the machining with adequate tolerance and the keyway according to standard. It is important not to exceed the maximum diameter so as not to compromise the strength of the hub.
- How do I request a quote for the A-50 or an equivalent?
- Write to us via WhatsApp with the code A-50 and the quantity you need. If you are looking for an equivalent from another brand, send us the equipment data: torque, shaft diameter and speed. We will reply shortly with the available options.
