Steady state and stability characteristics of hydrostatic two-layered porous oil journal bearings are obtained. The governing differential equations are solved numerically using the finite difference method for a wide range of design parameters. The effects of the eccentricity ratio, slenderness ratio, bearing number, feeding parameter and anisotropy of permeability on the load-carrying capacity, attitude angle, friction variable and oil flowrate have been investigated. Stability analysis has been performed using the linearized perturbation method. It has been observed that a two-layered porous bearing gives higher stability than a single-layered porous bearing.
