Top quality 6236M/C3VL0271 6236M/C3J20C 180x320x52mm electric Insocoat bearing for High voltage motor

Electrically insulated bearings use a special spraying process to spray a high-quality coating on the outer surface of the bearing. The coating has strong bonding force with the matrix and has good insulation performance. It can avoid the electroerosive effect of induced current on the bearing and prevent the current from affecting the grease and rolling elements. , damage caused by the raceway and improve the service life of the bearing.

The process is constantly being improved. In insulated bearings, there is a 100μm thick coating on the surface of the outer or inner ring, which can withstand voltages up to 1000 V DC. A special spraying process creates a coating of uniform thickness and strong adhesion, which is further treated to make it impervious to moisture and humidity.

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

Insulated bearings are suitable for motors and generators, especially variable-frequency motors.
