Cylindrical roller bearings which support thrust and/or moment loaidng in addition to pedominant radial loaidng have flanges on both the inner and outer rings to accommodate the thrust loaidng carried by the rollers. The roller thrust loading causes roller thrust loaidng causes roller tilting and friction moments about the rotating axis perpendicular to both the bearing and roller axis. The friction moments in turn give rise to roller skewing which increase roller-raceway loading, affecting bearing friction heat generation and fatigue endurance. This investigation shows the means of including the skewing effects in the analysis of overall bearing performance.
