The GUMMI A-350/250 flexible coupling is a power transmission component that joins two shafts and absorbs misalignment, vibration and torsional shock. Its design with two standard hubs and an elastic rubber center makes it suitable for demanding industrial applications, where high torque must be transmitted with a certain flexibility. It is used in mining, cement, steel and other heavy industry equipment. MR Accesorios Industriales sells it in Buenos Aires, Argentina, with more than 80 years of experience in the field.

This GUMMI Type A coupling, model A-350/250, has a configuration of two standard hubs (CN) and an elastic rubber center 1130 mm in diameter. The total length is 885 mm and the weight reaches 1211 kg. The nominal torque is 118750 Nm, with a maximum bore of 250 mm and a pilot bore of 120 mm. These characteristics position it as a robust solution for high-power transmissions.

Typical applications include mills, crushers, high-flow pumps, industrial fans and conveyor belt drives in cement, mining and steel plants. Its ability to compensate for angular and radial misalignment reduces wear on bearings and seals, extending equipment service life. It is common in environments with variable loads and frequent starts.

To correctly select this coupling, take into account the nominal torque required by the application, the diameter of the shafts to be joined and the environmental conditions. Assembly must be carried out with the hubs aligned within the tolerances recommended by the manufacturer, using the pilot bores as a reference for final machining. The elasticity of the rubber allows a certain tolerance to misalignment, but precise alignment maximizes the life of the elastic element.
