Status, causes and measures of bearing erosion

     Damage state: The so-called electric erosion refers to a phenomenon in which a current flows through a thin lubricating oil film when a circulating weight-bearing bearing race wheel and a contact portion of a rolling element flow, and localized melting and unevenness appear on the surface thereof.

Cause: The ground potential difference between the outer ring and the inner ring.

Action: When setting the circuit, the current will not flow through the bearing part. Insulate the bearing.
