Ceramic Coated Insulated roller Bearing with discount NU219 NU220 ECM C3 VL2071
Motor bearing insulation levels mainly include three categories:
1. General insulation: suitable for ordinary equipment and environments, with insulation resistance greater than 50MΩ;
2. High-resistance insulation: suitable for equipment and environments with high requirements, such as moisture, high temperature, high voltage, etc., with insulation resistance greater than 500MΩ;
3. Ultra-high resistance insulation: suitable for special environments, such as chemical industry, nuclear power, etc., with insulation resistance greater than 1000MΩ.
Choosing the appropriate motor bearing insulation level can improve the safety and stability of the equipment, reduce the failure rate, and extend the life of the equipment. It also helps protect staff safety.
Common types of electrically insulated bearings include: deep groove ball bearings, cylindrical roller bearings and angular contact ball bearings. Due to their good characteristics, they are widely used in various motor fields.
1. Cylindrical roller insulated bearings: wind turbines, hydroelectric generators, thermal generators and other power industry facilities and railway facilities such as diesel locomotive traction motors;
2. Deep groove ball insulated bearings: used in high-power variable frequency motors in cranes, textile machines, printing machines, iron making equipment, steel making equipment, steel rolling equipment, cutting equipment, coking equipment and other equipment.
