The GUMMI A-20 flexible coupling is a power transmission component that connects two shafts and absorbs misalignments and vibrations through an elastic rubber center. It is used in equipment where smooth starting and protection of the mechanisms are required. MR Accesorios Industriales sells this model with two standard hubs, a nominal torque of 38 Nm and a maximum bore of 20 mm.

This GUMMI A-20 coupling, from the Type A series, is configured with two standard hubs (CN). Its elastic rubber center has a diameter of 95 mm, and the assembly reaches a total length of 80 mm. The nominal torque is 38 Nm and it accepts a maximum bore of 20 mm. The 10 mm pilot hole allows the shaft seat to be machined to the required final size. The approximate weight is 1.05 kg.

It is used in centrifugal pumps, fans, screw compressors, conveyor belts and machine tools. It is common in installations where the goal is to reduce the transmission of vibrations and compensate for small misalignments between shafts. It is also used in low and medium power equipment that requires a flexible coupling with simple maintenance.

To select the coupling, check the nominal torque of the system and the diameter of the shafts to be connected. The maximum bore of 20 mm defines the limit for machining the hubs. It is important to check alignment during assembly to avoid parasitic loads on the elastic center. The two standard hub configuration allows the flexible element to be mounted between both hubs and secured with the corresponding screws.
