The present work exposes the vibration monitoring as a maintenance strategy for rotating equipment, being one of the most used techniques by the predictive maintenance. The present work provides information about the main types of maintenance existing, focusing on predictive maintenance by vibration analysis, where the main mechanical failures and their respective detections are addressed. The main objective is to prove this theory in a case study related to vibration monitoring of a centrifugal pump driven by an induction motor, in agreement with the company responsible for the equipment. The history of information and vibration graphics of the case study equipment were provided by the company, which has a vibration monitoring and analysis program already implemented. Most of the concepts of vibration analysis exposed in the present work were based on books and materials provided by the company. The results obtained were detections, by vibration analysis, of the occurrence of third stage rolling component failure in the equipment studied, proving the efficiency of the vibration collection and analysis method as an effective predictive maintenance technique for rotating equipment
