Method for detecting an incipient damage in a bearing

A computer implemented method for detecting an incipient damage in a bearing, the method comprising:

• receiving from a plurality of sensors of the bearing a plurality of signals corresponding to a plurality of bursts, each burst being emitted each time an indentation is met during a rotation of the bearing at a contact point between a roller of the bearing and a race of the bearing;
• analyzing the plurality of signals for locating on the bearing a plurality of indentations corresponding to the plurality of bursts;
• generating a map of points on a digital model of the bearing corresponding to the plurality of indentations on the bearing, the map of points being registered and updated throughout at least an interval of a lifetime of the bearing;
• identifying the incipient damage in the bearing each time a distribution of the points in the map is not random;
• and
• generating an incipient damage warning message.
