This study shows the benefits of the modern methods application of the predictive maintenance in order to detect and diagnosis of rolling bearings wear. From the large amount of domains where predictive maintenance has been applied, there have been chosen to be case studied the equipment which have rolling bearings as components. Rolling bearings are predisposed to a premature wear because of the execution and mounting quality, of the very numerous cycles of operation, of loading conditions during the production operation, or of the improper lubrication, etc.. By applying modern wear detection methods of rolling bearings, the causes of producing it can be identified and all of them could be set aside in order to get an increasing lifetime of rolling bearings and of the process equipment.
