This The concepts of rolling bearing rating life and basic loadrating (load carrying capacity) were introduced by Arvid Palmgrenin 1937 [1]. At that time, until the 1950s, most bearingmanufacturers listed in their catalogues the load admissible on thebearing for thousands hours of operation at five different speeds.In those days the selection of a bearing size for a givenapplication was a rather simple and approximate matter. The conceptof a single rating factor to characterize the dynamic capacity ofthe bearing was new and initially used only within the bearingcompany that developed this new technology. This rating method wasbacked by the theory of Lundberg & Palmgren (L-P) [2] and bythe Weibull statistics [3]. It was found that it could provide acorrect interpretation of the many series of endurance testsavailable at the time, [2], [4], [5]. This calculation methodprevailed on all the others methods used at the time and wasadopted by ISO in 1962.
