Abstract
A turbocharger includes a housing and a rotary assembly disposed within the housing and including a turbine wheel and a compressor wheel attached to one another by a shaft. A bearing is disposed in the housing and rotatably supports the shaft. The bearing includes a pair of inner bearing surfaces that engage opposite ends of the shaft and a pair of outer bearing surfaces that engage the housing. The pair of inner bearing surfaces have a first axial dimension and the pair of outer bearing surfaces have a second axial dimension that is smaller than the first axial dimension.
