The GUMMI A-25 is a flexible coupling that connects two shafts while compensating for misalignment, vibration, and torsional shock. Its elastic rubber center and two standard hubs (CN) make it a practical choice for soft starts and overload protection. Common applications include pumps, fans, conveyors, and machine tools.

This coupling belongs to the Type A series and uses a two standard hub configuration. It handles a nominal torque of 56 Nm and accepts a maximum bore of 23 mm. The pilot bore is 10 mm, the elastic center has a 95 mm diameter, and the overall length is 80 mm. Weight is 1.09 kg. These figures define its capacity for shafts up to 23 mm and its ability to dampen dynamic loads.

It is typically used in drives where small angular or radial misalignments need correction and where vibration transmission should be reduced. Centrifugal pumps, fans, blowers, conveyors, and machine tools are frequent hosts. The rubber element also smooths starts under variable loads, protecting bearings and gears downstream.

When selecting the A-25, confirm that the 56 Nm nominal torque covers your working load with a safety margin. The 23 mm maximum bore sets the shaft limit; larger shafts require a bigger model. The 10 mm pilot bore can be machined to the final shaft size. Before tightening the hubs, check shaft alignment, and inspect the elastic center periodically.

If you need an alternative, we can suggest an equivalent within the Type A series. Just provide the shaft diameter, required torque, and available dimensions. Our team will help you find the right fit for your application.
