Abstract
An exemplary bearing and locating pin system for a turbocharger includes a locating pin including a shaft, a head and an aperture and a bearing having a central axis and including an internal bore to receive a shaft extending between a compressor wheel and a turbine wheel, the internal bore including a plurality of axial grooves, the bearing including a locating pin aperture substantially equidistant from axial ends of the bearing for engaging the locating pin to prevent rotation of the bearing within a bearing case bore, the bearing further including a plurality of lubricant inlets, each inlet extending between an outer surface of the bearing and one of the axial grooves at an angle non-orthogonal to the central axis. Other exemplary technologies are also disclosed.
