Product Description

Insulated bearings are with insulation properties.Insulated bearings usually use insulation coatings applied to the inner or outer surface of the bearing to achieve insulation function.
This insulation coating can effectively prevent current from passing through the
bearing and prevent the occurrence of electrical corrosion

Advantage:
Preventing electrocorrosion: During the operation of the motor, shaft voltage and shaft current may be generated. When the current passes through the bearing, it will cause damage such as electrocorrosion pits and melting marks on the surface of the bearing raceway and rolling elements, affecting the service life of the bearing. Insulated bearings can prevent damage caused by electrical corrosion and ensure more reliable operation of motors and other equipment.
Reliability and cost-effectiveness: Compared with other insulation methods such as insulation treatment of shafts or shells, insulated bearings have more stable insulation performance, easier installation and maintenance, and are more cost-effective
Applications:
Power industry: generators.
Railway industry: diesel locomotive traction motor.
Mechanical and metallurgical industries: high-power variable frequency motors, etc
