The GUMMI A-300/250 flexible coupling is a power transmission component that connects two shafts and absorbs misalignments, vibrations and torque peaks. Its elastic rubber center allows smooth, quiet operation, protecting the connected equipment. It is used in industrial applications where high torques must be transmitted with a certain flexibility, such as mills, high-flow pumps, fans and conveyors. MR Accesorios Industriales carries this brand as part of its power transmission line.
This GUMMI A-300/250 coupling corresponds to Type A, with a two standard hubs (CN) configuration. According to its technical data, it handles a nominal torque of 86120 Nm, a maximum bore of 250 mm and a pilot bore of 100 mm. The elastic center has a diameter of 740 mm and the total length is 786 mm, with a weight of 640 kg. These dimensions allow it to be selected for large-diameter shafts and high-power applications.
Typical applications of this coupling include mill drives, crushers, high-flow centrifugal pumps, industrial fans and heavy-duty conveyors. Its rubber center design dampens torsional vibrations and compensates for angular and radial misalignments, reducing wear on bearings and gears. It is a robust solution for demanding environments where operational continuity is critical.
For assembly, verify that the shafts have the diameter and keyway length suitable for the maximum bore of 250 mm. The 100 mm pilot bore facilitates final machining according to the equipment's needs. It is important to align the hubs within the tolerances recommended by the manufacturer to avoid parasitic loads. Selection must consider the nominal torque of 86120 Nm and the service factors according to the application.
