A gantry assembly includes a rotor rotatable about a central axis, a stator fixed with respect to the axis and a bearing inner ring connected with the rotor and having an outer circumferential surface providing a least one inner raceway and two opposing axial end. A bearing outer ring is disposed about the inner ring and has an inner circumferential surface providing at least one outer raceway, first and second axial ends, an annular recess extending axially inwardly from the first axial end, and a plurality of threaded mounting holes extending axially-inwardly from the recess and spaced circumferentially about the central axis. An annular damper is disposed within the recess and a plurality of threaded fasteners each extend from the stator, through the damper and into a separate one of the plurality of threaded mounting holes to connect the bearing outer ring with the stator.
