NM coupling consists of two hubs and flexible ring able to compensate all types of shaft misalignment. The flexible rings are made of Nitile rubber (NBR) which have a high internal damping characteristic which enable to absorb and dampen torsional vibrations, operate effectively in temperature range of -40⁰C to +100⁰C.
The NBR material also resists to oil, dirt, grease, moisture, ozone and many chemical solvents.
