Flexible coupling GUMMI A-20/25 with axial hub

GUMMI A-20/25 CX belongs to coupling, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for A-20/25 CX and any equivalents.

The GUMMI A-20/25 CX is a flexible coupling that connects two shafts while compensating for misalignment, vibration and torque spikes. Its CX axial hub variant keeps the coupling from shifting along the shaft, making it suitable for machines where axial movement must be avoided. It serves as a practical replacement for rigid couplings or as a component for new builds.

This coupling belongs to the GUMMI Type A line, size A-20/25, and features an axial hub designated by the CX suffix. It fits shafts with a minimum diameter of 15 mm and a maximum of 21 mm. The design combines metallic hubs with an elastic element, allowing small angular and radial misalignments to be absorbed while torque is transmitted.

Common installations include centrifugal pumps, fans, screw compressors, conveyor belts and machine tools. The axial hub is especially useful when a thrust bearing locks the shaft position or when the machine cannot tolerate longitudinal displacement of the coupling. It also appears in gear motor drives where reducing vibration transfer and protecting bearings from parasitic loads is important.

When selecting the A-20/25 CX, confirm that your shaft diameters fall within the 15 to 21 mm range and that the axial configuration suits the equipment. During assembly, align the shafts as accurately as possible, follow the manufacturer's tolerances and ensure the elastic element is not pre-stressed. The coupling attaches to the shaft using set screws or keys, depending on the hub design. For further details, consult the GUMMI data sheet or contact us.

If you need an alternative, we can help you locate the right variant within the GUMMI Type A series. We offer 3,407 power transmission references and can guide you toward a model with a different shaft diameter or configuration. To do so, send us the coupling code you are looking for, the shaft diameter and the operating conditions. That allows us to give you a precise answer promptly.
