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 a rubber flexible center makes it suitable for demanding industrial applications, where a rated torque of 168,750 Nm must be transmitted with a maximum bore of 400 mm. MR Accesorios Industriales sells this reference backed in the industry.

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

Typical applications of this coupling include mill drives, 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 to ensure that the flexible center does not suffer permanent deformation. Selection must consider the rated torque of 168,750 Nm and the service conditions, such as shock or reversing operation.
