ABSTRACT:
A spherical bearing includes an outer ring formed integrally with a rod end, an inner ring having a spherical outer peripheral surface arranged in face-to-face relation with the inner peripheral surface of the outer ring, and a flexible lubricating sheet disposed between the inner peripheral surface of the outer ring and the spherical outer peripheral surface of the inner ring. Respective central portions in both annular areas of the flexible lubricating sheet which are respectively defined between an axial center of the outer ring and one annular end of the inner peripheral surface of the outer ring and between the axial center of the outer ring and another annular end of the inner peripheral surface of the outer ring are made to undergo plastic flow and are formed to be thinner than a remaining portion of the flexible lubricating sheet.
