The GUMMI A-165/165 flexible coupling links two shafts while compensating for misalignment, damping vibration and absorbing torque spikes. Its rubber center keeps operation smooth and quiet, which helps protect the connected machinery. Typical duties include pumps, fans, mills and conveyors where substantial power must move with some elasticity. This coupling is part of the range MR supplies.
This Type A unit, model A-165/165, comes with two standard hubs (CN). It is rated for a nominal torque of 12200 Nm and each hub accepts a maximum bore of 165 mm. The pilot bore measures 50 mm, leaving material for final machining to the shaft size. The rubber center has an outer diameter of 470 mm, and the complete assembly is 440 mm long. It weighs 135 kg. These figures make it a sturdy choice for heavy-duty transmissions.
You will find this coupling in mining, cement, steel, paper and water treatment plants. It drives centrifugal pumps, industrial fans, ball mills, conveyor belts and mixers. By reducing vibration and offsetting misalignment, it limits wear on bearings and seals, which supports longer machine life. It suits situations where high torque is transmitted with frequent starts or pulsating loads.
When selecting the A-165/165, check that the 12200 Nm nominal torque fits your power and speed after applying the service factor. The 165 mm maximum bore sets the upper limit for shaft diameter; smaller shafts are machined to match. The 50 mm pilot bore allows final sizing. Shaft alignment within the manufacturer's tolerances is important to prevent extra loads. The two standard hubs work for typical horizontal mounting.
