Bearings are among the most important components of electromotors, pumps, compressors and other processing equipment. After 30 years of work some non-destructive and metallographic examinations were carried out on a single-row cylindrical roller-bearing. A non-destructive liquid-penetrant testing revealed crack indications on an inner ring groove. When a sample of the roller-bearing outer ring was cut out for metallographic examination, new cracks were discovered that were not detected by the non-destructive testing. However, with the examination of the non-failed bearing it is possible to obtain useful information that can help us to decide how much of the remaining population of bearings with the same geometry and loading should be examined.
