Hydrodynamic bearings providing reduced friction are provided. The bearings include a load-transferring element and a porous bearing pad spaced from the load-transferring element. The load-transferring element is provided with a high-viscosity lubricant. The porous bearing pad is saturated with a low-viscosity lubricant. The high-viscosity lubricant and the low-viscosity lubricant are drawn into the clearance space by hydrodynamic action to form a bi-component lubricant film. The bi-component lubricant film includes a high-viscosity film layer and a low-viscosity film layer, which provide reduced viscous dissipation as well as proper cooling and lubrication.
