The GUMMI A-60 flexible coupling is a power transmission component that connects two shafts and absorbs misalignment, vibration and torque peaks. Its rubber flexible center works as a damper between the hubs, protecting bearings, gears and machine structures. It is used in pumps, fans, conveyor belts and process equipment where a flexible connection with simple maintenance is required. MR Accesorios Industriales supplies this GUMMI line in Buenos Aires, Argentina.

The A-60 model corresponds to the GUMMI Type A series, with a two standard hub configuration (CN). The flexible center has a diameter of 224 mm and the assembly measures 185 mm in overall length, with a weight of 12.5 kg. The rated torque is 620 Nm, the maximum bore reaches 55 mm and the pilot bore comes at 25 mm, ready to be machined to the shaft size. It is a medium-sized coupling, designed for transmissions with moderate loads and a need for damping.

Typical applications appear in drives for centrifugal pumps, fans, blowers, screw compressors, belts and elevators. It is also found in mixers, mills and process equipment where starting generates torque peaks that are best absorbed. In all these cases the rubber center reduces the transmission of vibration to the frame and compensates for small angular, radial and axial misalignments between the shafts, extending the service life of bearings and gears.

To select the A-60 properly, compare the rated torque of 620 Nm with the working torque of the drive and verify that the maximum bore of 55 mm covers the diameter of your shafts. The 25 mm pilot bore is machined to the final size with a keyway according to standard. During assembly, align the hubs with a straightedge or dial indicator before tightening, leave the axial clearance indicated by the manufacturer and do not force the flexible center. Check the condition of the rubber at every stop: cracks or hardening call for replacement.
