The journal bearings used associated with some other mechanical components is extensive, given their relative easy assembly and physical principles involved. This monograph introduces a case of efficiency of a set of bearings, already used, with good market acceptance. The component, now studied, is designed for work on a positive motion pump, model KD825-Uraca, where it is exposed to mechanical loads and continuous lubrication of fluids. Starting from these points of analysis, lubrication and mechanical loads, this work focuses on reviewing parts of the theoretical contents involved presented throughout the course. The purpose of the study is to suggest project improvements or to simply ratify the current project. Necessary data were taken from the technical manuals and in the eventual absence of information, physical measurements were taken of the machine. With computational aid, the sizing and design calculations were revised. It was proposed to use two different commercial lubricants with distinct viscosity values immediately lower and higher one. Based on the results obtained it can be assured that the base lubricant in operation is satisfactory and there are also substitution alternatives, although with some recommmendations
