This book fills a need in the literature by presenting a unified, up-to-date approach to the analysis of rolling bearing performance and is aimed at developing a basic understanding of rolling bearing operation. Going beyond the earlier editions, this Third Edition explores in greater detail such topics as materials, methods of testing and evaluation of test data, methods of lubrication and their usages. Also covers the initial development of a substantially improved and more accurate fatigue life theory. To accomplish this, early chapters discuss the simplest elements of rolling bearings such as basic bearing types, geometry, loading of single balls and rollers, contract stresses and deformations. Following this complex analysis of load distribution among the rolling elements, speeds and velocities, elastohydrodynamic lubrication, statistics of bearing endurance, fatigue life, friction and temperature are considered. Examples are included to clarify and highlight important concepts.
