Description

GUMMI A-30 is a flexible coupling reference, within Power transmission. Request a quote for A-30 via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.

The GUMMI A-30 flexible coupling is a power transmission component that joins two shafts and dampens vibrations and misalignments inherent to the 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 required. MR Accesorios Industriales sells it in Buenos Aires, Argentina, with more than 80 years of experience in power transmission.

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 coupling's capacity 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 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 mount 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 according to the actual shaft size. It is advisable to check the 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 a nearby size or an equivalent coupling, write to us on WhatsApp with the code A-30, the shaft diameter and the required torque. We can also guide you if you are looking for another hub configuration within the Type A series. We will reply shortly with the available alternatives.

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 verify the equipment's service factor 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 or a nearby size, we can also guide you within the Type A series.
