The GUMMI A-300/150 is a flexible coupling from the Type A series that links two shafts while allowing for misalignment, vibration and load peaks. Its elastic rubber center supports smooth, quiet running and helps protect driven equipment. This makes it a good fit for industrial drives that call for high torque capacity with some give.

The A-300/150 comes with a CN configuration, which means two standard hubs. Key figures are a nominal torque of 86120 Nm, a maximum bore of 150 mm and a pilot bore of 110 mm. The elastic center measures 740 mm in diameter, the overall length is 556 mm and the unit weighs 370 kg. Together these values suit high-power transmission duties.

You will often find this coupling on mill drives, crushers, high-flow pumps, industrial fans and mining or cement machinery. The rubber center absorbs angular and radial misalignment, which reduces the load on bearings and helps extend equipment life. It is also common where vibration needs damping and machinery must be shielded from overloads.

Before mounting, check shaft alignment and inspect the hubs. Follow the manufacturer's guidance on fits and tolerances. Selection should consider the torque required, the operating speed and the shaft diameter. The 110 mm pilot bore can be machined up to the 150 mm maximum bore to match the final shaft size.
