The GUMMI A-155 CI flexible coupling is a power transmission component that connects two shafts and absorbs misalignments, vibrations and torque peaks. Its integral hub (CI) configuration makes it suitable for larger diameter shafts, with a maximum bore of 200 mm. It is used in industrial equipment where continuous operation and protection of bearings and gears upstream are required. MR Accesorios Industriales supplies it in Buenos Aires, Argentina, with more than 80 years of experience in the field.

This coupling from the GUMMI Type A series is identified by the model A-155 and the CI variant, which means integral hub: the hub and the flexible element form a single piece, without external screws or jaws. The maximum allowable bore is 200 mm, which allows it to be mounted on large diameter shafts. The integral hub design simplifies mounting and reduces the number of components, resulting in greater robustness against shock loads and frequent reversals.

Typical applications of this coupling include drives for centrifugal pumps, fans, conveyor belts, mixers and mills, where torque must be transmitted with some flexibility to compensate for angular or radial misalignments. It is also used in continuous process equipment, such as those in the food, chemical or cement industry, where unscheduled downtime is costly. Its flexible construction helps dampen vibrations that would otherwise reach the bearings and seals.

To correctly select the coupling, take into account the shaft diameter, the nominal and maximum torque of the application, and the environmental conditions (temperature, presence of oils or dust). The maximum bore of 200 mm is a limit: if your shaft exceeds that size, it is advisable to evaluate another configuration. Also verify the alignment between shafts before tightening the hubs; careful alignment extends the life of the flexible element and prevents parasitic stresses.

If you need a nearby size or an equivalent coupling, write to us on WhatsApp with the code A-155 CI or with your shaft dimensions and the required torque. At MR Accesorios Industriales we advise you to find the variant that best suits your equipment. We can also quote other configurations of the Type A series, such as split hubs or models with a different bore, according to what your machine needs.

To request your quote, send the code A-155 CI on WhatsApp to MR Accesorios Industriales. We will reply shortly with the commercial and technical information you need. If you are looking for a coupling for a shaft up to 200 mm, this reference may be the right one; if you have doubts, ask us and we will help you define the best option for your application.
