Electric insulated bearings refer to the general term for bearings that can block the passage of current and have their own insulation properties. Electric insulated bearings use special spraying technology to spray high-quality film on the outer surface of the bearing. The film has strong adhesion with the substrate and good insulation performance. Therefore, the function of electric insulated bearings is to prevent current from passing through and have insulation performance. To avoid the electric corrosion effect of induced current on bearings, prevent damage to lubricating grease, rolling elements, and raceways caused by current, and improve the service life of bearings.
However, if chosen improperly electric insulated bearings, it may lead to the following problems:
Firstly, at high frequencies, the induced current in the rotor can be large, which may cause motor shaft current. The current will flow through the bearings to form a circulating current, and the bearings are prone to heating up or being damaged by electric sparks, resulting in safety issues.
Secondly, the local high temperature caused by the current can cause the additives in the lubricant to be burnt or burned, resulting in faster consumption of the additives. This rapid destruction greatly shortens the service life of lubricating grease and bearings.
Thirdly, electrical corrosion can damage the bearings in traction motors, electric motors, and generators and reduce their performance, resulting in costly shutdowns and unplanned maintenance.
