The Effect of Misalignment on the Fatigue Life of Cylindrical Roller Bearings Having Crowned Rolling Members

Abstract

An analytical method is presented to determine the effect of misalignment on the performance of cylindrical roller bearings having crowned rolling members. This method utilizes a more representative load-contact deflection relationship than used in previous analyses, and further, can be employed to estimate the degree of crowning required for a given application. Fatigue-life reduction owing to misalignment, as predicted by this method, is much less severe than has been previously estimated analytically.
