Reducing failures in machinery and equipment is the main objective of maintenance processes to increase production efficiency. Therefore, predictive maintenance processes seek to predict failures by detecting defective components. The bearing is the central component of studies for the development of failure detection systems, as bearing defects represent the main cause of failures in rotating machines. Diagnosing the presence of a defect and determining when to replace the bearing requires the installation of supervisory systems that, from sensors, collect data used to predict a failure. The diagnosis of defects in bearings is based on the analysis of the vibration signal, since mechanical defects change the vibration level. The High-Frequ...
