We measure generally mean frictional coefficient in order to know the moving state of lubricated machine. If correct analysis of frictional coefficient on working condition for lubricated machine can be possible, it can be effect on diagnosis of lubricated machine. But mean frictional coefficient of it is progressed always unstably with a large amplitude. In this case, it is difficult of measuring the correct frictional coefficient. The purpose of this study is, carried out to get the working condition with a minimum frictional coefficient of hydraulic actuator materials using statistical techniques.
