Electrically insulated bearing

The electric insulated bearing adopts special spraying process, and high-quality coating is sprayed on the outer surface of the bearing. The coating has strong adhesion with the substrate and good insulation performance, which can avoid the electric corrosion effect of induced current on the bearing, prevent the damage of current to lubricating grease, rolling body and raceway, and improve the service life of the bearing. The process is constantly improved. In insulated bearings, there is a layer of 100 on the surface of the outer ring or inner ring μ M thick coating, capable of withstanding voltages up to 1000 V DC. The special spraying process can form a layer of coating with uniform thickness and strong and uniform adhesion. After further treatment, it can not be affected by moisture and humidity. The electrically insulated bearing can avoid the damage caused by electric corrosion. Therefore, compared with ordinary bearings, it can ensure more reliable operation in motors. Compared with other insulation methods, such as shaft or shell insulation, it is more cost-effective and reliable. The overall dimensions and basic technical characteristics of insulated bearings are the same as those of non insulated bearings, so they can be 100% interchangeable.
