In this research, an example of the results obtained from the combination of the vibration monitoring program and the root cause analysis approach for the electromotor roller element bearings of the cement factory’s mill fan has been examined and presented. By registering the inspectors’ reports on the release of abnormal sound from the bearings, the vibration data recorded in the monitoring program indicates the change of vibration trends and sensible increase in the bearing condition index (BC). By matching the vibration frequency with defect frequency of the elements of roller bearing, the defect in the bearing cage was predicted. Diagnosis of the root cause of failure was on the agenda for this aim. The defect of the bearing was detected after investigation of the root cause of failure in the bearings. The type of bearing used in the electromotor by the electromotor manufacturer was not suitable considering its operating characteristics, and the proposed periodic lubrication interval has not suitable for the type of related cage bearing and has resulted to its destruction.
