Ceramic Insulated Bearings
Our new line of WWI KEKAO-T ceramic insulated bearings, and ceramic hybrid insulated bearings, are ideally suited to prevent the micro-welding associated with high voltage bearing applications. The ceramic coating material creates a barrier against any stray currents passing through the bearing. Ceramic insulated, high voltage bearings can be used in industrial motors and generators, wind turbine generators, high-voltage motors, variable frequency motors, traction motors, engraving machines, high speed trains etc.
Electrical current leakage from equipment such as motors and power generators often causes pitting or micro-welding. Commonly this issue can be caused by an asymmetrical motor magnet circuit, unshielded power cables and fast switching PWM converters used in variable frequency drives. If electrical current is able to flow through the bearing then small sparks will result in damage to the inner and outer race, and this damage eventually leads to bearing failure. To prevent bearing failure in electrical applications ceramic coated insulated bearings or ceramic hybrid bearings can be used.
