A discussion of models for the behaviour of gas bearings, particularly of the aspects affecting the stability of the system. The text begins with a discussion of the mathematical models, identifying the stiffness and damping coefficients, and describing the behaviour of the models in unstable regions. It then turns to apply these results to bearings: static characteristics and stability of various rotor systems and an extensive discussion of air rings.

The book discusses the basic principles and equations governing Hydrodynamic, Hydrostatic, Elastohydrodynamic and Gas Lubrication. The author has made an effort to explain the theory and present an exposition of the fundamentals of fluid film bearings, rolling element bearings, friction and wear of metals.
