Abstract
A bearing for supporting a load for axial and rotational motion relative to a shaft is disclosed as including an outer shell having a cylindrical inner wall supporting a plurality of circumferentially spaced arcuate bearing pads for engaging the shaft. Each bearing pad includes a pair of elastically deformable lateral tip portions arranged for interference fit with the shaft to exert a static preload on the shaft, and a mid portion intermediate the lateral tip portions arranged for clearance fit with the shaft. A plurality of lubricant channels communicate with the shaft through gaps between the separate bearing pads.
