This paper is concerned with the reduction of the power loss of the thrust bearing. A thrust bearing with a disk floated by externally pressurized oil is proposed, and the static characteristics of the thrust bearing are investigated by experiments and simplified analysis in the laminar regime. As a result, the following conclusions are obtained: The power loss of the thrust bearing decreases by approximately one-half of the same-shaped hydrostatic bearing without any disk. The disk is floating nearly in the middle of the oil film. The rotational speed of the disk is about one-half of the shaft rotational speed. The floating position of the disk and the disk rotational speed do not influence the power loss very much.
