The GUMMI A-70 flexible coupling is a power transmission component that joins two shafts and absorbs misalignments, vibrations and load peaks. Its rubber flexible center allows smooth and 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.

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 flexible center has a diameter of 224 mm, while the total 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 vibrations and allows compensating angular and radial misalignments, 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 flexible element and avoid parasitic loads that could damage the equipment.
