Shock Pulse Measurement of Bearings: Extracts from papers presented at an SKF symposium held at Stockholm this Spring describing a new technique of detecting damage to ball and roller bearings Available to Purchase

WHEN a rolling bearing is damaged as a result of fatigue, spalling occurs cither on the ring tracks or on the surface of rolling elements. As a roller or a ball rolls over these spalls, which are depressions in the surfaces of the rings also known as flaking, impacts occur.
