Successful operation of a 50 kb-1000C rock deformation shear press depends on frictionless operation of two thrust bearings; an upper bearing must transmit undiminished 30,000 inch-pounds of torque to a mineral test specimen, and the lower bearing must permit free rotation of a torque measuring arm under maximum torques of 7000 inch-pounds. Upper bearing friction coefficients as low as 0.01 result when colloidal bonded films containing 65 percent pure MoS2 in an alkyd resin are used with MoS2 greases. The torque arm bearing is lubricated with 0.01 inch thick Teflon sheet to obtain friction coefficients below 0.016. Bearing pressures occasionally exceed 100,000 psi in both bearings, however no evidence of galling, seizing or wear have developed on any thrust plate. Torque losses do not exceed 5 percent of the transmitted value in the upper bearing and 3.5 percent in the lower bearing. (Author).

Hydrodynamic Lubrication is the culmination of over 20 years close, collaborative work by the five authors and discusses the practical use of the formalization of low pressure lubrication. The work concentrates on the developments to journal and thrust bearings and includes subjects such as: • the dynamic behaviour of plain and tilting-pads • the thermal aspects • the positive and negative effects of non-cyclindricity and shape defects resulting from manufacturing or operation • the effects of inertia • the appearance of Taylor's vortices and of turbulence and their repercussions. The book contains an abundance of test results objectively compared with theoretical conclusions and a chapter on "technical considerations" to ensure that draft mechanisms will work satisfactorily under the imposed conditions. Hydrodynamic Lubrication is an essential reference book for future and practising engineers who want to put hydrodynamic and hydrostatic journal bearings and thrust bearings into operation under conditions of total safety.

Hydrostatic and Hybrid Bearing Design is a 15-chapter book that focuses on the bearing design and testing. This book first describes the application of hydrostatic bearings, as well as the device pressure, flow, force, power, and temperature. Subsequent chapters discuss the load and flow rate of thrust pads; circuit design, flow control, load, and stiffness; and the basis of the design procedures and selection of tolerances. The specific types of bearings, their design, dynamics, and experimental methods and testing are also shown. This book will be very valuable to students of engineering design and lubrication.
