On the Causes and Effects of Roller Skewing in Cylindrical Roller Bearings

Abstract

Abstract Cylindrical roller bearings which support thrust and/or moment loading in addition to predominant radial loading have flanges on both the inner and outer rings to accommodate the thrust loading carried by the rollers. The roller thrust loading 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 increases 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.
