This is a review of selected publications over the past eight years, dealing with the analysis and design of self-acting, gas-lubricated bearings. An effort has been made to evaluate the advances made both in the understanding of the basic phenomena involved and in the technical analytical ability to deal with them. Whenever possible, design procedures have been referenced and illustrated.

T his paper deals with the effects of lubricant compressibility on th e pressure profil e and t otal load capacity in a partial journal bearing; piv ot pressure as a measure of shoe load capacity ; shoe friction characteristics; and optimum shoe clearance ratio s for various speeds . The parameter A is used as an indicator of the com pressibility effect of gas in the bearing clearance. Nomenclature CRadial clearance between shoe and shaft = R shoe -R sha ft C'Pivot circle radial clearance = R pl vot -R sb art C,

The paper presents experimental and theoretical data on the axisymmetric hydrostatic thrust bearing with one bonded compliant surface. The theoretical results are exact and are based on linear elasticity theory. The effects of compliance on the behavior of the thrust bearing are discussed and illustrated.
