This is the author’s version of a work that was accepted for publication in the journal, Tribology International. Changes resulting from the publishing process, such as peer review, editing, corrections, structural formatting, and other quality control mechanisms may not be reflected in this document. Changes may have been made to this work since it was submitted for publication. A definitive version was subsequently published at: http://dx.doi.org/10.1016/j.triboint.2010.02.016This paper introduces an analytical approach to study the textured surfaces in\ud hydrodynamic lubrication regime. For this purpose, a method of integrating the\ud Reynolds equation for slider bearings with surface discontinuities is presented. By\ud introducing appropriate dimensionless parameters, analytical relations for various\ud texture profiles in both indented and projected forms are delivered. These relations\ud express the nature of mathematical dependence between textured bearing performance\ud measures and geometrical/operational parameters. An optimisation procedure is\ud employed to achieve the optimum texturing parameters promoting maximum load\ud capacity, load capacity to lubricant flow rate ratio and minimum friction coefficient\ud for asymmetric partially textured slider bearings
