This paper reports a case of lubricating property test of bearing. In order to seize the performance and the reasonable work condition of Ф480mm elliptical bearing with groove on all pads for 1000MW steam turbine, an experimental method that load is on the rotor was adopted in this paper. And the test focused on the bearing characteristics which is most concerned by designers such as power loses, temperature, flow, and flow state, etc. The influence on power loses, temperature rise, flow by the temperature and pressure of inlet oil, load, speed was studied in this test. The results show that the flow state in this bearing is changed from laminar to turbulent in the speed range 2000rpm~2200rpm and in the Reynolds number range 1325.8~1556.5. The specific pressure for the bearing with groove on the down pad is proper between 1.57MPa and 1.96MPa.
