An X-ray tube bearing includes an outer housing having an axial bore, a shaft at least partially received within the axial bore, a first outer ring positioned within the axial bore and surrounding a first portion of the shaft, and a second outer ring at least partially received within the axial bore and surrounding a second portion of the shaft. The second outer ring includes a radially outwardly extending flange engaged with the outer housing to limit the extent to which the second outer ring is received within the axial bore. The X-ray tube bearing also includes a first biasing member biasing the flange into engagement with the outer housing, and a second biasing member positioned within the axial bore for exerting an axial preload force between the first and second outer rings.
