SKF bearing electrical erosion is to point to the current in the cycle of rolling bearing turn heavy way round and rolling body contact part of the flow, through the thin oil film is a spark, its surface appear to melt and the local convex phenomenon.

Current is usually bearing applications cannot avoid reality. Current through the rolling bearing, with potentially damaging consequences. Damage occurs mainly in the ball or roller bearing SKF with inside and outside the circle groove contact surface.

 
SKF in view of this long-standing electrical erosion problems, have found the solution: from current injury insulation bearing, namely INSOCOAT, its coating protection from the damage caused by current bearing. Through the investigation including lubrication, rotating electrical system of a bearing all parts, SKF think it can reduce the current in the bearing to harmless level.
