A flexible joint is used to accommodate dynamic movement such as settlement, seismic and thermal movements. A portion of an outer surface of a ring is surrounded by a sleeve. A coupling attaches the sleeve to the ring. The sleeve is slidably movable on a section of the portion of the outer surface of the ring. The portion of the outer surface comprises first and second grooves, a partial spherical segment, a first frustoconical segment positioned adjacent the partial spherical segment and a second frustoconical segment positioned adjacent the partial spherical segment. The outer surfaces of the first and second frustoconical segments taper away from the partial spherical segment.
