The present disclosure provides a gantry of a CT scanner. The gantry includes an annular outer support having a radially inwardly facing, continuous circumferencial bearing chamber, an annular drum concentrically positioned within the outer support and having a continuous circumferential bearing lip radially extending into the bearing chamber of the outer support to define two circumferential bearing runs within the bearing chamber, and an annular disk extending radially inwardly from an inner circumferential surface of the drum. The disk is adapted to receive and support computed tomography components. The gantry also includes roller bearings in the bearing runs rotatably supporting the drum within the outer support, such that the drum and the disk are rotatable about a rotation axis of the drum. |
