Oil flow rate to tilting pad thrust hearings influences two important bearing operating characteristics; bearing power loss and pad operating temperatures. Reducing oil flow rates is desirable as this reduces the size and cost of the oil supplysystem and also can reduce bearing power losses. However, this can increase bearing operating temperatures, reducing the load capacity. Results of laboratory tests of thrust hearings with babbitt faced pads are reported in which oil flow rates were varied and losses and temperatures were measured.
