NM couplings are offered in the industry’s largest variety of stock bore/keyway combinations.
Product Description
NM couplings are offered in the industry’s largest variety of stock bore/keyway combinations. These couplings require no lubrication and provide highly reliable service for light, medium, and heavy duty electrical motor and internal combustion power transmission applications. Applications include power transmission to industrial equipment such as pumps, gear boxes, compressors, blowers, mixers, and conveyors.
NM coupling consists of two hubs and flexible ring able to compensate all types of shaft misalignments. 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 -40 °C to +100 °C. The NBR material also resists to oil, dirt, grease, moisture, ozone and many chemical solvents.
