Condition based maintenance (CBM) philosophy uses a variety of monitoring techniques in order to assess the necessity of repair actions prior to a system’s defect occurring. The methods that can be used for machinery evaluation include techniques such as vibration analysis, thermography, acoustic emission, oil and wear particle analysis. The aforementioned techniques are a potential asset of any maintenance personnel that aims to reduce the life cycle cost of industrial equipment. The aim of this paper is to present an example of the application of vibration analysis as an efficient, cost-effective and reliable maintenance technique for motor bearings fault diagnosis.
