Abstract
In a diagnostic system, having a rotating gantry () and a stationary gantry (), a bearing race () rotates with surface portions having varying linear velocities in accordance with distance from an axis (A) of rotation. Tapered roller bearings () interface the bearing race () and are conically shaped to velocity match the variable linear surface velocity race (). The race () preferably includes two faces, which provide both axial and radial supporting surfaces for the bearings () to interface. The bearings () are disposed about the race () in pairs. A drive motor () is connected to one of the bearings () to rotate the gantry ().
