An imaging system (100) includes a stationary gantry (102), a rotating gantry (104) that rotates around an examination region about a z-axis, an annular support (106) that is statically affixed to the stationary gantry and that rotatably couples the rotating gantry to the stationary gantry, and a radial compliant ring (108) disposed between the annular support and the rotating gantry. In a variation, the imaging system also includes an axial compliant ring (112) disposed perpendicular to the radial compliant ring, statically affixed to the annular support and extending in part in a recess (206) of the rotating gantry.
