NM is the core range on this site. The catalogue-derived related products are shown separately so buyers can compare adjacent coupling constructions without confusing them with NM model data.

Source-pack HRC, pump-claw and star-coupling families kept separate from NM specifications.
View related families →NM couplings use two hubs with an elastomer ring between them. That arrangement gives a simple way to transmit torque while adding damping and limited misalignment accommodation.
Pumps are a major use case, but the same selection questions appear on compressors, blowers, mixers, conveyors and motor-to-gearbox connections: torque, speed, shaft interface, starts, shock and alignment.
Picking by outside diameter alone is not enough. A model must make sense for the duty and still accept the shaft interface.
Start with operating torque or motor power and speed, then account for the actual duty rather than nameplate data alone.
Choose a model whose published nominal torque and speed limit cover the operating point.
Confirm each bore, keyway and available envelope against d max, D, D1 and L.
State quantity, destination, elastomer request, material request and any unusual starts, reversing or environment.
We focus on Germany, India, Italy, the United States and Japan while supporting projects across Western Europe, South Asia, North America and East Asia. Market pages explain the information we need without implying a local warehouse or office.

Send motor power, running speed, both shaft diameters, keyways, driven equipment and quantity. We can use that information to narrow the range before the detailed quotation.
