Description
GUMMI A-30 is a reference of flexible coupling, within Power transmission. Request a quote for A-30 via WhatsApp or email with the quantity you need; we respond promptly with the quote and equivalents.
The GUMMI A-30 flexible coupling is a power transmission component that connects two shafts and dampens the vibrations and misalignments inherent to assembly. Its elastic rubber center absorbs torque peaks and reduces noise transmission between machines. It is used in pumps, fans, compressors and conveyors, where a simple, low-maintenance connection is needed. MR Accesorios Industriales sells it in Buenos Aires, Argentina.
The GUMMI A-30 belongs to the Type A series and is assembled with two standard hubs (CN) and an elastic rubber center. The nominal torque is 82 Nm, the maximum bore per hub reaches 30 mm and the pilot hole measures 10 mm. The elastic center has a diameter of 127 mm, the total length is 110 mm and the weight is 2.4 kg. These values define the capacity of the coupling and guide the selection against the shaft and the equipment load.
Typical applications include centrifugal pumps, fans, screw compressors, conveyors and machine tools. In all cases, the coupling compensates for small angular and radial misalignments, and filters the vibrations that would otherwise reach the gearbox or the motor. It is a common solution in installations where a quiet transmission with few lubrication points is sought.
To assemble the A-30, check that the shaft diameter does not exceed 30 mm and that the working torque does not exceed 82 Nm. The 10 mm pilot hole allows the final bore to be machined to the actual shaft size. It is advisable to check alignment between both hubs before tightening the set screws and to inspect the condition of the elastic center under pulsating loads or frequent starts.
If you need an equivalent coupling, write to us on WhatsApp with the code A-30, the shaft diameter and the required torque. We can also advise you if you are looking for another hub configuration within the Type A series. We will reply shortly with the corresponding options.

Frequently Asked Questions
- What torque does the GUMMI A-30 coupling accept?
- The nominal torque is 82 Nm. For loads with peaks or frequent starts, it is advisable to leave a safety margin and check the service factor of the equipment before confirming the model.
- Up to what shaft diameter can it be machined?
- The maximum bore per hub is 30 mm. The 10 mm pilot hole allows the hub to be brought to the final shaft size. If your shaft exceeds that diameter, ask us about a larger size.
- How do I request a quote or an equivalent?
- Write to us on WhatsApp with the code A-30, the shaft diameter and the working torque. If you need another configuration, we can also advise you within the Type A series.
