The GUMMI A-90 flexible coupling is a power transmission component that connects two shafts and absorbs misalignment, vibration and torque peaks. Its rubber flexible center works in compression and allows smooth operation in equipment with variable loads. It is used in pumps, fans, compressors and conveyors. MR Accesorios Industriales sells this model with two normal hubs, ready to mount in industrial applications that demand reliability and low maintenance.

The GUMMI A-90 belongs to the Type A series and comes with a two normal hub configuration (CN). Its nominal torque is 2170 Nm, with a maximum bore of 85 mm and a pilot hole of 30 mm. The flexible center has a diameter of 302 mm, an overall length of 250 mm and a weight of 26 kg. These characteristics position it as a robust option for transmitting power between shafts in demanding industrial assemblies.

Typical applications include centrifugal pumps, fans, screw compressors, conveyors and machine tools. In all cases, the flexible coupling compensates for small angular, radial and axial misalignments, reducing the vibrations that reach the bearings and extending the service life of the assembly. It is a common solution in chemical, food and water treatment plants.

To correctly select a GUMMI Type A coupling, take into account the required nominal torque, the diameter of the shafts to be connected and the service conditions. The maximum bore of 85 mm and the pilot hole of 30 mm define the possible machining range. It is important to verify initial alignment and use the appropriate fastening elements. The rubber flexible center should be inspected periodically to detect wear or aging.
