An X-ray table of the tiltable type in which a tower assembly is movably carried by a table body. The tower assembly includes a mast or column that is carried by a carriage and movable relative to the carriage in a path transverse to the longitudinal extent of the table. The carriage is longitudinally movable relative to the table body. The carriage support is provided by cylindrical ways and bearing clusters each including four circumferentially spaced bearings that are arranged in diametrically opposed pairs. One bearing of each pair is eccentrically mounted for preload adjustment. The bearings of one pair are positioned such that their axes are perpendicular to the plane of resultant forces imposed on the bearings and the ways when the table is in a vertical orientation.
