Abstract
A life-cycle prognosis is created of a rolling-element bearing. As from manufacturing of the bearing and during the bearing's life-cycle that may include periods of the bearing's non-use, service life data is obtained indicative of one or more factors that occur during the life-cycle and that affect the length of the life-cycle. The service life data is obtained together with identification data that is representative of a machine-readable identifier, applied to the bearing at manufacturing. The identifier serves to uniquely identify the bearing throughout its life. The identification data is used for identifying in a database a history log of the bearing. The service life data is accumulated in the history log of the bearing as from the manufacturing. The history log is used with a specific mathematical life-cycle model for creating an update of the life-cycle prognosis.
