Electrically insulated bearings adopt a special spraying process to spray high-quality film on the outer surface of the bearing. The film has strong bonding force with the substrate and good insulation performance, which can avoid the electric corrosion effect of the induced current on the bearing and prevent the current from affecting the grease and rolling elements. , The damage caused by the raceway improves the service life of the bearing. The process has been continuously improved. In insulated bearings, there is a 100 μm thick coating on the surface of the outer or inner ring, which can withstand voltages up to 1000 V DC.
