Using Histograms in the Selection Process for Tapered Roller Bearings 810993

Advances in computer technology and the published results of extensive bearing research and empirical testing, have allowed designers to expand the traditional catalog approach and optimize the selection process for tapered roller bearings. This paper explores many of the factors influencing bearing selection where fatigue life is the primary concern, and describes how the Bearing Systems Analysis (BSA) approach, as used by The Timken Company, incorporates the effect of many of these environmental variables. Particular attention is paid to the formation and analysis of the load-speed spectrum, or histogram, and to the vital part it plays in the bearing selection process.
