The GUMMI A-70 flexible coupling is a power transmission component that joins two shafts and absorbs misalignment, vibration and load peaks. Its elastic rubber center allows smooth, quiet operation, protecting the coupled equipment. It is used in a wide variety of industrial applications where reliability and low maintenance are required. At MR Accesorios Industriales we sell it as part of our power transmission line, with more than 80 years of experience in the Argentine market.

The GUMMI A-70 belongs to the Type A series and is configured with two standard hubs (CN). Its technical specifications include a nominal torque of 1170 Nm, a maximum bore of 65 mm and a pilot bore of 25 mm. The elastic center has a diameter of 224 mm, while the overall length of the coupling is 185 mm and its weight reaches 13.3 kg. These characteristics position it as a robust solution for transmitting power in demanding systems.

This coupling is typically used in centrifugal pumps, compressors, fans, conveyor belts and mills, among other rotating equipment. Its rubber center design dampens torsional vibration and compensates for angular and radial misalignment, which reduces wear on bearings and seals. It is a reliable option for the food, chemical, petrochemical and general process industries, where operational continuity is critical.

To correctly select a GUMMI A-70 coupling, take into account the torque required by the application, the rotation speed and the diameter of the shafts to be connected. The maximum bore of 65 mm and the pilot bore of 25 mm allow the hubs to be machined to the final dimensions. It is essential to verify alignment during assembly to maximize the service life of the elastic element and avoid parasitic loads that could damage the equipment.
