Bearing reliability is essential in industrial systems, and their vibration monitoring remains a challenge for anticipating failures. In this work, two classic scalar indicators were considered: the root mean square (RMS) value and kurtosis. This allowed for the development of a new indicator that takes into account the number of peaks exceeding the RMS value. The results obtained on two datasets, one with four different frequencies (10, 20, 30, and 40 Hz) and the other with a single frequency of 24 Hz, are promising. The RMS and kurtosis indicators are limited in their ability to detect different types of defects. It is in this context that, in this work, we developed a new scalar indicator, X, obtained using the two indicators mentioned above. This indicator offers more reliable and robust discrimination of bearing conditions and allows not only the detection of a defect but also a better characterization of its nature. Full-scale tests will validate this new indicator for its simple use in analyzers for the analysis of stationary signals in the time domain.
