The GUMMI A-80 CI flexible coupling is a power transmission component that connects two shafts and absorbs misalignment, vibration and load peaks. Its integral hub (CI) configuration makes it suitable for larger diameter shafts, with a maximum bore of 100 mm. It is used in equipment where continuous operation and protection of the bearings and gears downstream are required. MR Accesorios Industriales supplies this line with technical advice to select the correct size.

This item is a flexible coupling from the GUMMI Type A series, model A-80, with an integral hub configuration, identified as CI. The integral hub replaces the split hub and is machined directly on the coupling body, which simplifies mounting and improves concentricity. The maximum bore accepts shafts up to 100 mm in diameter. The designation A-80 CI summarizes the model and its construction variant, and is used to order the exact spare or replacement.

Typical applications for this coupling include centrifugal pumps, fans, screw compressors, conveyor belts and machine tools. In process plants, water treatment or mining, the A-80 CI flexible coupling is placed between the motor and the driven machine to dampen irregular torque and compensate for small angular and radial misalignments. It is also used in equipment where access for mounting is limited, because the integral hub reduces the number of parts to handle.

To correctly select the coupling, take into account the shaft diameter, the nominal torque and starting peaks, the rotation speed and the working environment. The maximum bore of 100 mm defines the limit for this model; if your shaft exceeds that measurement, a larger model is required. Check alignment with a straightedge or dial indicator before tightening the connecting elements, and check the condition of the elastomer: a worn element transmits vibration and accelerates bearing wear.

If you need an equivalent, message us on WhatsApp with the code A-80 CI or with the model shown on your equipment's nameplate. You can also send the shaft diameter, the distance between shaft ends and a photo of the assembly. With that data, the technical team at MR Accesorios Industriales identifies the variant that best fits and replies shortly.
