Condition monitoring is gaining importance because of its advantages over conventional maintenance methods. Even though it is little costly, It is feasible especially in continuous process industries, where process costs are very High. In this paper, an attempt is made to monitor bearing faults. In condition monitoring through vibration analysis, it is possible to predict different defects of different characteristics and would reveal the details of defects and inaccuracies so that it could be minimized, which leads to increase the plant efficiency. Condition monitoring through vibration analysis is an online technique, where we need not stop the machine for diagnosing the fault.
