Abstract
Journal and/or thrust bearings of a high speed rotary machine are mounted on a portion of the machine stator by mounts which allow limited tracking of pivotal rotor displacements by the bearings to reduce the risk of bearing damage due to nonuniform bearing pressurization from such pivotal shaft displacements. The mounts resist radial and axial shaft displacements for maintenance of sufficient shaft-stator alignment to prevent risk of rotor-stator impact.
