The efficiency of the hydrodynamic journal bearing is one of the most important factors in operating high load machinery, thus it requires better performance and reliability. Applying boundary slip and surface texturing onto the bearing surface are some of the most common approaches in increasing bearing performance. In this paper, the comparative analysis is done by involving boundary slip, no-slip and the combination of slip and no-slip on the textured surface. The load capacity acts as a benchmark for the bearing's performance based on several parameters. Based on the results obtained, increasing texture length will produce a positive improvement over the load capacity. Besides, various surface configurations act differently in different eccentricity ratio, thus providing better configuration selection on different operating conditions. © 2006-2017 Asian Research Publishing Network (ARPN).
