China Professional NM Coupling Supplier – High Quality and Cost-effective

The NM coupling is a well-known flexible coupling that is widely used in compressors, diesel engines, pumps, conveyors, and other drive units. It consists of two hubs and a flexible ring capable of compensating for all types of shaft misalignments. The flexible ring is made of Nitile rubber(NBR), which has a high internal damping characteristic that enables it to absorb and dampen torsional vibrations. The NM coupling operates effectively in a temperature range of -40~+100. It is quiet and smooth in operation, easy to install, and maintenance-free. It is available to machine with high torque and intermittent operation. The NM coupling is offered in different models, such as NM50, NM67, NM82, NM97, NM12, NM128, NM148, NM168, NM194, and NM214.
