The GUMMI A-170 CI flexible coupling is a power transmission component that joins two shafts and absorbs misalignments, vibrations and torque peaks. Its integral hub (CI) configuration is designed for larger diameter shafts, with a maximum bore of 250 mm. It is used in equipment where operational continuity and machinery protection are required. MR Accesorios Industriales sells this GUMMI line in Buenos Aires, Argentina, with more than 80 years of experience in the field.

This coupling corresponds to model A-170 of the GUMMI Type A series, in its integral hub (CI) version. The integral hub replaces the conventional split hub and allows a maximum bore of 250 mm, which makes it suitable for large diameter shafts. The designation A-170 CI identifies both the size and the hub configuration. It is a power transmission part that works through elastic deformation of its flexible elements, without the need for lubrication.

Typical applications include drives for mills, conveyor belts, centrifugal pumps, industrial fans and large machine tools. In all cases, the coupling fulfills the function of transmitting torque from the motor or gearbox to the driven shaft, filtering running irregularities and compensating small angular, radial and axial alignment errors. It is commonly seen in installations where predictive maintenance and vibration reduction are priorities.

To correctly select a GUMMI A-170 CI coupling, take into account the shaft diameter, the nominal and maximum torque of the drive, and the working environmental conditions. The integral hub requires precise machining of the housing and careful alignment during assembly, since it does not allow later corrections by disassembling the hub. Also verify the rotation speed and the type of load to choose the right elastic element within the Type A series.
