Abstract: The present paper investigated the solution of Maxwell fluid in sliding bearings utilitying an universal form of Reynolds equation and assuming existing a linearied relation between stress and rate of strain in that viscoelastic fluid. The influence of nonlinear effect of Maxwell fluid on pressure distribution, bearing load capacity, peak pressure and friction coefficient was calculated and the analytical solution of three nonlinear functions in modified Reynolds equation were also obtained.
