Bearing is a critical component in any machine as most of failures occurring in rotating machinery are due to bearings. Although bearing is suitably chosen for a particular application but still for some specific applications like railways and aircrafts, world-renowned manufactures like SKF and NBC prefer to do coating on it to improve the properties hence remaining useful life (RUL). Properties like roughness, hardness, wear resistance could be improved as per the requirement of the practical use. In this study, different coatings on the bearing are analysed with their respective grade of tribological properties from the available literature. Firstly, the relation of tribological and mechanical properties of the coatings was co-related with the practical usage of the bearing. Thereafter, the degradation in the properties of bearing coatings over the usage of time was discussed along with conventional techniques available for the measurement of properties. It was observed that the conventional techniques were having number of challenges in measurement of properties as bearing needed to be dismantled or even damaged. To overcome this challenge vibration-based techniques were finally proposed to detect these changes in the properties because of their sensitivity to detect even small changes in the vibration signature. It is also suggested that if vibrational based techniques could be implemented in detecting the property changes, then the remaining useful life can be predicted more accurately.
