Abstract
An assembly can include a turbocharger center housing that includes a through bore that extends between a compressor end and a turbine end of the turbocharger center housing where the through bore includes a sleeve mating surface; and a sleeve positioned at least in part in the through bore of the turbocharger center housing where the sleeve includes an outer mating surface, an inner compressor side bearing lubricant film formation surface disposed at a first radius, an inner turbine side bearing lubricant film formation surface disposed at a second radius, and a surface between the inner compressor side bearing lubricant film formation surface and the inner turbine side bearing lubricant film formation surface that includes a third radius that is less than the first radius and less than the second radius and where outer mating surface of the sleeve contacts the sleeve mating surface of the turbocharger center.
