The paper proposes a concentric hydrodynamic journal bearing constructed by the boundary slippage, which is opposed by conventional lubrication theory. Analysis for the carried load and friction coefficient of this bearing is presented. The optimum condition for the maximum load-carrying capacity of this bearing is examined. It is shown that the whole circumference of the bearing should be taken as the lubricated area, while on most of the stationary surface of the bearing there should be a hydrophobic coating covered so that the boundary slippage would occur on this surface, In this condition, the load-carrying capacity of the bearing is the highest but its friction coefficient is the lowest.
