The GUMMI A-90 CI flexible coupling is a power transmission component that connects two shafts and absorbs misalignment, vibration and load peaks. Its integral hub (CI) configuration is designed for larger diameter shafts, with a maximum bore of 100 mm. It is used in equipment where continuous operation and protection of bearings and gears are required. MR Accesorios Industriales supplies it in Buenos Aires, Argentina, with more than 80 years of experience in power transmission.

The GUMMI A-90 CI belongs to the Type A series and is identified by its designation A-90 CI. The letters CI stand for integral hub, a construction variant that simplifies mounting and adds rigidity to the assembly. Its maximum bore is 100 mm, which makes it suitable for larger diameter shafts. The intermediate elastic element compensates for angular and radial misalignment within the permissible values for this type of coupling. It is a replacement or project part selected by shaft diameter and by the torque it must transmit.

Typical applications of this coupling are found in machines with continuous drive: centrifugal pumps, fans, screw compressors, conveyor belts and process equipment. It is also found in the food, chemical and water treatment sectors, where the goal is to reduce vibration transmission between motor and driven machine. Because it has an integral hub, it is practical in spaces where mounting with separate hubs complicates alignment. It is a flexible transmission solution for medium power and large diameter shafts.

To select the A-90 CI, take into account the shaft diameter, nominal torque and operating speed. Shaft alignment must be checked with a straightedge or dial indicator before tightening the hubs: excessive misalignment shortens the life of the elastic element. Fastening screws must be tightened to the torque recommended by the manufacturer, with the hub clean and free of burrs. If the coupling operates in a dusty or humid environment, periodically check the condition of the elastomer and replace it if it shows cracks or hardening.
