Locating mechanism for turbocharger bearing

An exemplary semi-floating bearing for a turbocharger has a central axis defining a cylindrical coordinate system with an axial direction, a radial direction and an angular direction; a turbine end (108); a compressor end (104); journal surfaces (112,114) between the turbine end and the compressor end, the surfaces configured to support a turbocharger shaft (140); and an opening disposed between the turbine end and the compressor end, the opening having a radial dimension that exceeds an axial dimension to, upon receipt of a locating pin, provide for movement of the bearing in the angular direction about its central axis and to provide for lesser movement of the bearing in the axial direction. Other exemplary bearings, arrangements and methods are also disclosed.
