Analysis of Rolling Element Bearings provides a comprehensive introduction into the theory and design of rolling element bearings.

In any rotating machinery system, the bearing has traditionally been a crit ical member of the entire system, since it is the component that permits the relative motion between the stationary and moving parts. Depending on the application, a number of different bearing types have been used, such as oil-lubricated hydrodynamic bearings, gas bearings, magnetic suspensions, rolling element bearings, etc. Hydrodynamic bearings can provide any desired load support, but they are limited in stiffness and the associated power loss may be quite large. Gas bearings are used for high-precision applications where the supported loads are relatively light, bearing power losses are very low, and the rotating speeds generally high. For super precision components where no frictional dissipation or bearing power loss can be tolerated, magnetic suspensions are employed; again, the load support requirements are very low. Rolling element bearings have been widely used for those applications that require greater bearing versatility, due to the requirements for high-load and high-stiffness characteristics, while allowing moderate power loss and permitting variable speeds. A study of the dynamic interaction of rolling elements is, therefore, the subject of this text. Texts covering the analysis and design methodology of rolling elements are very limited. Notable works include Analysis of Stresses and Deflections (Jones, 1946, Vols. I and II), Ball and Roller Bearings, Their Theory, Design and Application (Eschmann, Hasbargen, and Weigand, 1958), Ball and Roller Bearing Engineering (Palmgren, 1959, 3rd ed. ), Advanced Bearing Technology (Bisson and Anderson, 1965), and Rolling Bearing Analysis (Harris, 1966).

Part of the fifth edition of the classic Rolling Bearing Analysis, this book examines bearing performance and service life for more complex loading, more extreme operating conditions, and higher-speed applications. Several topics are unique to this work, including mathematical relationships for internal load distribution under conditions of high speed, combined radial, axial, and moment loading, as well as the effects of various types of profiling. The authors also delve into the mathematical development of rolling element-raceway lubricant film thickness and contact friction, the stress-life method for calculating bearing fatigue, and the effects of shaft and supporting structure flexure on bearing loading and deflection.

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.
