Application of electrically insulated bearings

The electrically insulated bearings adopts a special spraying process. The outer surface of the bearing is spray-plated with a high-quality coating. The coating and the substrate have a strong binding force and good insulation performance. It can avoid the electric corrosion of the bearing by the induced current and prevent the current from affecting the grease and rolling elements. The damage caused by the raceway increases the service life of the bearing. The process is continuously improved. In the electrically insulated bearing, there is a layer with a thickness of 100 μm on the surface of the outer ring or the inner ring, which can withstand a voltage of up to 1000 V DC. The special spraying process can form a coating with uniform thickness and extremely strong adhesion, and then further processing to make it immune to the influence of moisture and humidity.

Electrically insulated bearings can avoid damage caused by electrical corrosion, so compared with ordinary bearings, they can ensure more reliable operation in motors. Compared with other insulation methods, such as shaft or housing insulation, it is more cost-effective and reliable. The dimensions and basic technical characteristics of insulated bearings are the same as those of non-insulated bearings, so they are 100% interchangeable.
