Ceramic-Coated Bearings

NSK’s Ceramic-Coated Ball Bearings with high insulation resistance are optimal for applications that are susceptible to electrical corrosion. Ceramic-coated ball bearings are plasma sprayed to ensure a proper bonding to the bearing steel. The coating is sealed with a special acrylic resin that helps prevent significant deterioration of electrical resistance.
These bearings are supplied across the world for industrial motors & generators, traction motors and wind energy applications.
