Many lubricants demonstrate non-Newtonian behaviours. Rheological measurements indicate that some flows of these lubricants may by modelled as the flows of a Vočadlo fluid. In this paper theoretical aspects of hydrostatic lubrication of a curvilinear thrust bearing lubricated by a Vočadlo fluid are considered. The bearing is modeled by two surfaces of revolution having a common axis of symmetry.The effects of inertia of a longitudinal flow of the Vočadlo lubricant on the pressure distribution in a bearing clearance are examined by using the method of averaged inertia. As examples step and spherical bearings are discussed.
