The bearing is provided with a bore to rotatably receive the shaft of a rotational component and is pressed into a generally cylindrical socket wherein the projections shave at least some axial length of the inside wall of the socket to a precise fit preventing rotation of the bearing therein. The precise fit extends a relatively short axial distance, resulting in clearance features between the outer surface of the assembled bearing and the socket wall which permit limited angular displacement of the bearing and allow the bearing to self align relative to the socket and yet maintain sufficient alignment to permit easy assembly of a shaft within the bearing. | |
