What is Diagnosing Frequent Bearing Failures about?
The document discusses two case studies of premature and frequent failures of anti-friction bearings in rotating machinery. In both cases, traditional vibration-based bearing monitoring identified faults but could not determine the root cause of the frequent failures. Modal testing of the complete machine systems identified structural resonances that were likely triggering misalignments and overloading the bearings. Case 1 involved a pump where a structural mode near 2x rotational speed was amplifying vibra
