The GUMMI A-80 CI is a flexible coupling used to join two shafts while taking up misalignment, vibration and torque peaks. Its integral hub design, identified as CI, suits larger shafts and allows a maximum bore of 100 mm. It is common in equipment that runs continuously and where the bearings and gears downstream need protection. MR Industrial Accessories supplies this line and helps buyers confirm the right size.

This coupling belongs to the GUMMI Type A family, model A-80, in the integral hub version known as CI. Instead of a separate split hub, the hub is machined as one piece with the coupling body, which cuts down on parts during assembly and keeps the bore concentric. Shafts up to 100 mm in diameter fit the maximum bore. The code A-80 CI identifies both the model and its construction, so it is the reference to use when ordering a replacement.

You will find this coupling on centrifugal pumps, fans, screw compressors, conveyor drives and machine tools. In process plants, water treatment facilities and mining operations, it sits between the motor and the driven machine to smooth out uneven torque and absorb small angular and radial misalignments. Its one-piece hub also helps where there is little room to work, since fewer components have to be handled during installation.

When selecting a size, look at the shaft diameter, the nominal and starting torque, the speed and the surrounding conditions. The 100 mm bore is the ceiling for this model; a shaft above that calls for a larger frame. Before tightening the connecting elements, confirm alignment with a straightedge or dial indicator. Also inspect the elastomer, because a worn element passes vibration through and shortens bearing life.

For an equivalent, send the code A-80 CI or the model on your equipment nameplate by WhatsApp. Adding the shaft diameter, the gap between shaft ends and a photo of the assembly helps the MR Industrial Accessories team pinpoint the correct variant and reply quickly.

MR Industrial Accessories carries the GUMMI line alongside other power transmission products. To get a quote on the A-80 CI or to ask about other Type A configurations, send the code by WhatsApp or email. The process is simple: you send the details, we confirm the size and prepare the quote.
