Insulation bearing

Electric insulated bearings adopt a special spraying process, which sprays high-quality film on the outer surface of the bearing. The film has strong adhesion to the substrate, good insulation performance, and can avoid the electric corrosion effect of induced current on the bearing, prevent damage caused by current to the lubricating grease, rolling element, and raceway, and improve the service life of the bearing. This process has been continuously improved, and in insulated bearings, there is a layer of 100 on the surface of the outer or inner ring μ The m-thick coating can withstand a voltage of up to 1000 V DC. A special spraying process can form a layer of coating with uniform thickness and extremely strong adhesion, which is further treated to be unaffected by moisture and humidity.

Advantage：

Electric insulated bearings can avoid damage caused by electrical corrosion, so compared to ordinary bearings, their application in motors can ensure more reliable operation. Compared to other insulation methods, such as shaft or shell insulation, it is more cost-effective and reliable. The external dimensions and basic technical characteristics of insulated bearings are the same as non insulated bearings, so they can be 100% interchangeable. Suitable for motors, generators, especially variable frequency motors, which are more widely used.

The main categories of electrically insulated bearing products are: electrically insulated deep groove ball bearings, electrically insulated angular contact ball bearings, electrically insulated cylindrical roller bearings, inner or outer ring insulated bearings with oxide coating and mixed bearings with electrically insulated ceramic rollers.
