The GUMMI A-105 CI is a flexible coupling used to link two shafts while allowing for misalignment, vibration and torque spikes. Its integral hub (CI) design suits larger shafts, with a maximum bore of 125 mm. It is found in machinery that runs continuously and needs protection. MR Industrial Accessories supplies this coupling to customers across the United States and in several Latin American countries.

This coupling belongs to the GUMMI Type A series and carries the model A-105 with a CI configuration. In the CI version, the hub and flange are made as one piece, which gives the coupling higher rigidity and greater transmission capacity. The largest shaft it can accept is 125 mm in diameter. The code A-105 CI points to this exact variant in the GUMMI range.

You will see it on centrifugal pumps, fans, compressors, conveyor belts and machine tools. In these setups, the flexible element takes up small angular, radial and axial misalignments and reduces torsional vibration. It is often chosen when the motor and the driven machine sit on separate bases and some flexibility is needed to keep bearings and seals from being overstressed.

When selecting an A-105 CI, check the shaft diameter, the torque to be transmitted, the rpm and the load type. The 125 mm maximum bore is a hard limit. Shaft alignment also matters: even though the flexible part tolerates some misalignment, poor alignment speeds up wear. Use the correct keys during assembly and a fit that prevents excessive play.

If you are looking for an alternative, ask about the A-105 in other configurations or other Type A couplings with different bores. Send the code or model you need through WhatsApp or email and our team will respond promptly. We can suggest equivalents and help you choose the right coupling for the application.
