A theoretical aspect of lubrication of a curvilinear thrust bearing by conducting and magnetic viscoelastic fluids is considered. The effects of centrifugal (rotational) inertia forces on the pressure distribution in the presence of a magnetic field, normal to the bearing surfaces, are examined. The examples of flows in the bearings modelled by two disks and two concentric spheres are discussed. The obtained results show that the fluid inertia forces and magnetic field have significant effects on the pressure distribution.
