  • Turbocharger integrated bearing system
    Patent number: 6017184
    Abstract: An integrated bearing system with journal and thrust bearings is incorporated in a single unit centrally pinned to the bearing housing and having integral thrust surface and journal surface lubrication grooves in combination with turbine and compressor wheel thrust surfaces. The bearing employs a first aperture substantially equidistant from the ends to engage the locating pin to prevent rotation of the bearing within the bearing case bore, while allowing the bearing to be free to symmetrically wobble within the bearing case bore.
