Assembly with bearings and spacer

A turbocharger comprising:

• a housing that comprises a through bore formed at least in part by a turbine side bore wall, a compressor side bore wall and a spacer bore wall disposed between the turbine side bore wall and the compressor side bore wall;
• a turbine side rolling element bearing assembly disposed adjacent the turbine side bore wall of the through bore of the housing wherein the turbine side rolling element bearing assembly comprises an outer race and wherein a radial clearance exists between the outer race and the turbine side bore wall of the through bore of the housing;
• a compressor side rolling element bearing assembly disposed adjacent the compressor side bore wall of the through bore of the housing wherein the compressor side rolling element bearing assembly comprises an outer race and wherein a radial clearance exists between the outer race and the compressor side bore wall of the through bore of the housing;
• and
• a spacer secured in the housing between the turbine side rolling element bearing assembly and the compressor side rolling element bearing assembly via an interference fit with the spacer bore wall of the through bore of the housing wherein the spacer forms a turbine side axial stop that limits the axial position of the outer race of the turbine side rolling element bearing assembly and forms a compressor side axial stop that limits the axial position of the outer race of the compressor side rolling element bearing assembly.
