The influence of inertia effect on the pressure distribution in a curvilinear thrust bearing with a viscoplastic squeeze film is considered. To solve this problem the boundary layer equations are used. The method of integral approaches is applied and the formulae expressing the pressure distribution are obtained. This distribution for Ostwald - de Waele, Bingham and Herschel - Bulkley fluids in the clearance between two disks is discussed in detail. It is found that the pressure increases with an increase of inertia effects and decreases with a decrease of the flow behaviour index N.
