Abstract: Surface texturing is helpful in decreasing the friction, decreasing the wear, and increasing the fluid film stiffness. This investigation studies the influence of micro-pit arrangement on the behavior of gas parallel slider bearings (GPSB) by employing the multi-grid finite element method using the Matlab software. The pressure distribution of GPSB with micro-pits was investigated. The results showed that the position offset ratio of micro-pits had negligible effect on the maximum pressure and minimum pressure of GPSB with micro-pits. Meanwhile, the effect of the geometrical parameters of micro-pits on the average pressure of GPSB was investigated for different position offset ratios. Geometrical parameters of micro-pits included depth of micro-pits, radius of micro-pits, transversal spacing, longitudinal boundary distance, and longitudinal spacing. It was found that both depth and radius of micro-pits corresponding to maximized average pressure were controlled by the position offset ratio of micro-pits. The findings of this paper imply that the optimized micro-pit arrangement could improve the hydrodynamic pressure of gas parallel slider bearings.
