analysis of the chemical composition using a spectrometer – identification of the material grade
hardness testing – definition of the type of processing
visual analysis – definition of the degree of degradation of rolling elements and bearing raceway
ultrasound testing – definition of subsurface faults
magnetic and particle testing – definition of the degree of crack propagation
analysis of measurement data, definition of the causes of damage to the bearing
