Electrically insulated bearings use a special spraying process to apply a high-quality coating to the outer surface of the bearing.
Electrically insulated bearings use a special spraying process to apply a high-quality coating to the outer surface of the bearing. The coating has high adhesion strength to the base and good insulating properties. It avoids electrical erosion damage to the bearing by induced currents, prevents damage to the lubricant, rolling elements and raceways under the influence of current, and also increases the service life of the bearing. This process is constantly being improved. In electrically insulated bearings, a 100 micron thick coating is applied to the surface of the outer or inner ring, capable of withstanding voltages up to 1000 V DC. A special spraying process allows the formation of a layer of uniform thickness with high adhesion and uniform coverage, and subsequent processing provides protection from moisture and dampness.
