Abstract: The invention resides in a bearing device for an exhaust gas turbocharger, comprising a first radial bearing and a second radial bearing configured for the radial support of a shaft of the exhaust gas turbocharger, wherein the first radial bearing comprises a bearing axis extending in alignment with the bearing axis of the second radial bearing which is arranged spaced from the first radial bearing, a third radial bearing with a third bearing axis which is extends parallel to, but at a distance (E) from, the first bearing axis and the second bearing axis is arranged between the first and second radial bearings. The invention resides also in a turbocharger including such a bearing device.
