Preface

The special qualities of pressurized hydrostatic, aerostatic, and hybrid bearings afford a simple and convenient solution to many bearing problems experienced with particular machines. Sometimes, the best method of achieving a specified performance is to use a hydrostatic bearing, an aerostatic bearing, or a hybrid bearing. However, the designer is not always experi-enced in hydrostatic and aerostatic lubrication, and has difficulty obtaining authoritative guid-ance presented in a simple manner.

This book has been written with this problem in mind and is based on the author’s personal experience over many years in bearing design and testing, in running courses on this subject for industry, and in writing articles for the technical press.

Theory is kept to an elementary level in the design sections and the book offers a useful intro-duction for engineers who have left academic study behind. A basic theory chapter refreshes relevant principles of fluids. The book is also useful to students of engineering design and lubri-cation. There is growing awareness in universities and colleges of the importance of tribology for reliability and effectiveness of all moving devices and mechanisms. This book covers important sectors of thin-film lubrication and machine design.

Acknowledgements are due to many valued colleagues, particularly Dr J. P. O’Donoghue, Dr K. J. Stout, Dr D. A. Koshal, Dr F. S. Chong, Professor K. Cheng, Professor W. Weston, and Dr D. Ives, main colleagues with whom analysis, computing, and experimental investigation were developed. A considerable volume of experimental work undertaken over the years has contrib-uted to understanding where theory fits with reality and, more importantly, where it diverges. Great care has been paid to ensure accuracy in the design guidance given in this book. But, however carefully the text has been checked, some readers may find ambiguity. The technique of presenting and explaining principles wherever possible, followed by procedures and ex-amples, allows the reader to cross-check intentions and overcome such problems.
