Abstract
A bearing for supporting a rotating shaft receiving a transverse load, wherein the bearing supports the shaft along a load line and wherein the bearing is closest to the rotating shaft at a running line. The bearing includes a circumferential inner surface, and a lubricant bay defined in the inner surface. The lubricant bay is axially and circumferentially offset from the load line such that a resulting pressure pad of lubricant within the bay provides a hydrostatic force that forces the running line to a location substantially perpendicular to the load line. Load capabilities of a bearing according to the present disclosure, therefore, are substantially insensitive to shaft bending and do not deteriorate in response to the shaft bending.
