Turbocharger bearing assembly and method for providing the same

Abstract:

An integrated bearing assembly includes a thrust bearing disposed along a face of a turbocharger casing in a turbocharger and extending circumferentially around an axis of rotation of a rotor of the turbocharger, and a dual film journal bearing radially disposed between the rotor and the turbocharger casing which can be semi-floating or fully floating. The journal bearing includes a shoulder step radially extending away from the rotor. The shoulder step of the journal bearing engages one or more of the thrust bearing or the turbocharger casing to prevent axial movement of the dual film journal bearing relative to the turbocharger casing.
