The present paper describes the performance of a capillary compensated hole-entry hydrostatic/hybrid symmetric journal bearing system operating with micropolar lubricant. The numerical solution of the modified Reynolds equation governing the flow of the micropolar lubricant is obtained using finite element method. The results presented in this paper indicate that the two parameters, non-dimensional characteristic length (l m ) and coupling number (N 2) of the micropolar lubricant affect the static and dynamic performance characteristics of bearing and herein these characteristics have been compared with that of Newtonian lubricant.
