Based upon the micropolar fluid model, the effects of non-Newtonian fluids on the load- carrying capacity of composite slider bearings are considered. According to the results, the use of non-Newtonian micropolar fluids provides an increase in the load performances of composite slider bearings. The increasing load due to the non-Newtonian micropolar fluids are further emphasized for larger values of the non-dimensional interacting parameter and the non-dimensional coupling parameter. Keywords: micropolar fluids, non-Newtonian rheology, composite slider bearings *E-ma
