Short fillers have been widely used as reinforcing agents due to their successful effects on composite materials. However, studies for short fillers were mainly focusing on even dispersion of fillers in the composite system. As for the application related to bearing, the fillers needed to be deposited on the surface to improve the physical and tribological properties. Therefore, in this study, the fundamental of micro bearing concept was imparted by relating to the rheological study of polymer. These relations can be supported by the theory of particulate fillers in suspensions according to Modified Mooney-Einstein’s Theory of Viscosity. The Ultra High Molecular Weight Polyethylene (UHMWPE) fillers, which possess high wear resistance, were fabricated with epoxy resin. The mixture was prepared by diluting with acetone solvent and varying the filler loadings percentage for 1%, 3%, 5%, 7%, and 10%, accordingly. Based on the results observed, there were increment up to 41.7% for viscosity value. For the wear test, the results showed decrease in the wear rate up to 72.0%. For the hardness test, the results indicate increment in the hardness value up to 94% compared to UHMWPE alone. For the density test, the results showed decrease in the density value up to 3.8%.
