The GUMMI A-400/400 flexible coupling is a power transmission component designed to connect shafts and absorb misalignment, vibration and torsional shock. Its configuration of two standard hubs (CN) and rubber elastic center makes it suitable for demanding industrial applications, where a nominal torque of 168,750 Nm must be transmitted with a maximum bore of 400 mm. MR Accesorios Industriales supplies this reference backed by more than 80 years in the industry.

This GUMMI Type A-400/400 coupling comes with two standard hubs (CN), a 120 mm pilot bore and an elastic center of 1130 mm diameter. The total length is 1085 mm and its weight reaches 2245 kg. The specified nominal torque is 168,750 Nm, which positions it as a robust solution for high-power transmissions. These construction features allow compensating angular and radial misalignments within the elastic limits of the rubber.

Typical applications of this coupling include drives for mills, crushers, high-flow pumps, industrial fans and mining or cement equipment. Its ability to dampen torque peaks and reduce vibration transmission makes it a reliable option in continuous process lines. It is also used in transmission systems where a certain flexibility is required to protect bearings and gears upstream and downstream.

For assembly, it is essential to verify shaft alignment before coupling. The maximum bore of 400 mm and the 120 mm pilot bore allow the final diameter to be machined according to the shaft. It is recommended to check the tightening torque of the fastening elements and ensure that the elastic center does not suffer permanent deformation. Selection must consider the nominal torque of 168,750 Nm and the service conditions, such as shocks or reversals.
