An arrangement for connecting a turret within a vessel opening such that the vessel is capable of rotation about a longitudinal axis of the turret. The arrangement including an inner ring assembly coupled to the turret and an outer ring assembly coupled to the vessel in concentric alignment with the inner ring assembly. A support row assembly connected between the inner and outer ring assemblies allows rotation of the outer ring assembly with respect to the inner ring assembly and axially transfers the weight of the turret to the vessel. A radial row assembly is coaxially disposed about the longitudinal axis between the inner and outer ring assemblies. A centralizer is disposed between the inner and outer ring assemblies. During normal operation the radial row assembly transfers any radial load from the vessel to the turret and the centralizer has a radial clearance with the outer ring assembly.
