Review on prospect of rolling element bearings failures, comparison of bearing life and its estimation using on-line condition monitoring techniques

ABSTRACT The present work focuses on the condition monitoring techniques/methods used for the rolling element bearings to predict the fault and its propagation sothat early bearing failure can be monitored. Because if the propagating failure is not monitored then it can lead to the ruinous failure to the entire system, which can further lead to costs of unplanned repair and loss of production. Several methods such as acoustic emission, vibration analysis, optical interferometry etc. have been compared and relative analysis is done.
