Lubricated contact problems are stiction that causes inherent between surfaces. It is necessary to give effect to the surface so it cannot absorb water or hydrophobic. Currently, many research results that the hydrophobic nature of surface engineering in addition to heterogeneous slip/no-slip and textured surface can also improve the distribution of the pressure for better lubrication. Surface texture rectangular type is applied in this study. The purpose of this study is to analyze performance lubrication produced by the combination of surface texture and has slip properties on surface contact. Modeling of lubricated contacts is infinite width model. Solved modeling using finite volume method, the solution is divided into a finite number of control volumes, and a modified Reynolds equation discrete and applied to each control volume. Modifications done by assuming that the slip in a linear fashion following the shear rate (the Navier-slip). Variations in the length of slip are also done. Simulation results show that surface texture of rectangular slip has a positive effect on lubrication performance improvement. It is characterized by increasing the maximum point of pressure distribution of two-fold when compared with a given surface without texture. Giving the slip length is large (super-hydrophobic surface) are also beneficial. Practically, the two results are expected to help improve the lubrication performance in each engine components that are in contact, not only on the slider bearing.
