The GUMMI A-25 flexible coupling is a power transmission component that joins two shafts and absorbs misalignment, vibration and torsional shock. Its elastic rubber center and two standard hubs make it suitable for equipment requiring soft starts and overload protection. It is used in pumps, fans, conveyor belts and machine tools. MR Accesorios Industriales sells it in Buenos Aires, Argentina, with technical advice to choose the right size.

The GUMMI A-25 belongs to the Type A series, with a two standard hub (CN) configuration. It has a nominal torque of 56 Nm, a maximum bore of 23 mm and a pilot bore of 10 mm. The elastic center measures 95 mm in diameter, the overall length is 80 mm and the weight reaches 1.09 kg. These values define its capacity to transmit power on shafts up to 23 mm, with an elasticity that dampens dynamic loads.

It is used in drives where small angular or radial misalignments must be compensated and vibration transmission reduced. It is common in centrifugal pumps, fans, blowers, conveyors and machine tools. It also appears in low and medium power equipment that starts under variable loads, where the rubber of the elastic center provides smoothness and protects bearings and gears downstream.

To select it, check that the nominal torque of 56 Nm covers the working load with a safety margin. The maximum bore of 23 mm limits the shaft diameter; if you need more, you must move up to a larger model. The 10 mm pilot bore allows the final bore to be machined according to the shaft. Check the alignment between shafts before tightening the hubs and check the condition of the elastic center periodically.

If the A-25 does not fit your size, we can offer you an equivalent or a neighboring size within the Type A series. To do so, send us the shaft diameter, the required torque and the available dimensions. With that data, the technical team at MR Accesorios Industriales looks for the alternative that best suits your application.
