Bearing faults are one of the most probable causes for machine vibra-tion. Early detections on bearing faults can save invaluable time and cost. In practice, vibration analysis is one of the techniques of condition-based mainten-ance that allows early detection and reliable diagnosis of bearing faults. In this paper, a test rig is implemented to bring a reliable approach for monitoring and diagnosis. A full spectrum analysis, derived from the fast Fourier transforma-tion, is presented for the vibration signal to reveal combined fault signature of bearing. However, a monitoring system based on an artificial neural network (ANN) model is used to diagnose combined faults in bearings. To train and test the ANN, coded faults are used as output data. To determine the best ANN, a learning algorithm has been chosen and maintained. The proposed method gives more reliable diagnosis in complex faults scenario. Also, the best model can be used by practitioners in the industry as a decision support tool to increase the availability of the machine.
