The GUMMI A-20 CI flexible coupling is a power transmission component that connects two shafts and absorbs misalignment, vibration and torsional shock. Its integral hub (CI) configuration makes it suitable for larger diameter shafts, with a maximum bore of 30 mm. It is used in a wide variety of industrial machines, from pumps and fans to conveyors and mixers, where smooth and reliable transmission is required.

This coupling from the GUMMI Type A series is identified by model A-20 and the integral hub (CI) configuration. Integral hub means that the elastic element and the hub form a single piece, which simplifies assembly and reduces the number of components. The maximum bore accommodated is 30 mm, which allows its use on larger diameter shafts within this series. This designation corresponds to Table IV of the GUMMI Type A catalogue, intended for applications with higher torque requirements.

Typical applications of this coupling include centrifugal pumps, fans, blowers, belt conveyors, mixers and agitators. In all these cases, the flexible coupling compensates for small angular and radial misalignments, dampens vibration and protects the machine's bearings and gears. Its integral hub design is especially useful in equipment where space is limited and maintenance is to be minimized.

To correctly select the coupling, take into account the shaft diameter, the torque to be transmitted, the revolutions per minute and the type of load. The maximum bore of 30 mm is a limit that must not be exceeded. Also check the operating temperature and the presence of chemical agents that could affect the elastomer. Assembly requires aligning the shafts as precisely as possible to extend the service life of the elastic element.
