The effects of centrifugal inertia forces on the pressure distribution in a curvilinear thrust bearing lubricated by a generalized second grade fluid of power-law type are examined. The examples of flows in the bearings modelled by two disks and two concentric spheres are considered. The results obtained show that fluid inertia forces have significant effects on the pressure distributions.
