The first challenge is to develop greases that will provide longer life and\/or are able to operate under more severe conditions (extreme low and high temperature and speed). The second challenge is the development of predictive tools, such as numerical models or expert systems. The third challenge is to design bearing systems that increase grease life. All of these aspects require a fundamental understanding of the lubrication mechanisms of greases. \u003c\/p\u003e \u003cp\u003e\u003ci\u003eGrease Lubrication in Rolling Bearings\u003c\/i\u003e provides an overview of the existing knowledge on the various aspects of grease lubrication (including lubrication systems) and the state of the art models that exist today. This book reviews the physical and chemical aspects of grease lubrication, primarily directed toward lubrication of rolling bearings. The first part of the book covers grease composition, properties and rheology, including thermal and dynamic properties. Later chapters cover the dynamics of greased bearings, grease flow, oil bleeding, film thickness, aging, grease life, bearing life, reliability, seals, condition monitoring and testing.
