A finite-difference numerical model is used to study the influence of surface textures configuration and depth on lubrication performance of hydrodynamic journal bearing. Reynolds equation is adopted to calculate the bearing dimensionless load carrying capacity, friction force and friction coefficient under different eccentricity ratio, textures configuration and depth. Results show that partial texturing in the inlet zone with shallow dimples and in the cavitation zone with deep dimples could improve bearing performance appreciably. The effect of the textures on bearing tribological performance was influenced by the eccentricity ratio. The advantage of partial textures decreases when the eccentricity ratio increases.
