Failure modes, White Etching Cracks (WECs) and White Etching Areas (WEAs), ap-pear prevalently in rolling contact bearings. There is still a lack of efficient methods to identify such failure modes as early as possible before the visible crack appears on the bearing surface. In this article, a comparison was done between the measured opera-tional deflection shapes (ODS) from a rolling contact bearing with and without WECs and WEAs. The measurement was obtained by using a...
