Abstract:
1. An assembly for a turbocharger comprising: a housing comprising a substantially cylindrical bore having a longitudinal axis, an inner diameter, a proximate end and a distal end and a counterbore positioned at the distal end, substantially centered on the longitudinal axis and having an inner diameter; a bearing cartridge substantially centered on the longitudinal axis between the proximate end and the distal end and comprising a unitary outer race, the unitary outer race having an outer diameter at a proximate end, an outer diameter at a distal end, an inner diameter at a proximate end and an inner diameter at a distal end, and an inner race; and a compressor plate positioned at the proximate end, the plate including an opening substantially centered on the longitudinal axis and having an inner diameter less than the outer diameter at the proximate end of the unitary outer race wherein the inner diameter of the counterbore is less than the outer diameter at the distal end of the unitary outer race wherein the inner diameter of the cylindrical bore exceeds the outer diameter of the unitary outer race, the inner diameter of the counterbore and the inner diameter of the opening of the plate, and wherein the counterbore and the plate limit axial movement of the unitary outer race of the bearing cartridge.
