A center housing rotating assembly (CHRA) for a turbocharger, the CHRA comprising: a ball bearing cartridge, wherein the ball bearing cartridge comprises an inner race having an inner race rotational axis (z IR) and an outer surface disposed at an outer surface radius (r IR,O), an outer race having an outer race rotational axis (z OR) and an inner surface disposed at an inner surface radius (r OR,I), and two sets of ball bearings (234, 234') disposed between the inner race and the outer race wherein the inner surface radius (r OR,I) of the inner surface of the outer race increases toward ends of the ball bearing cartridge; a shaft; wherein the ball bearing cartridge and the shaft are formed as a balanced ball bearing cartridge and shaft subassembly (230, 520), the subassembly (230, 520) balanced as a unit in a clamp without a compressor wheel attached thereto, wherein, with respect to the outer race, the inner race translates an axial distance (Δz internal) and tilts an angle (Θ internal) to alter clearances (Δr internal) between the ball bearings and the outer surface of the inner race and the inner surface of the outer race, the angle (Θ internal) providing for control of the clearances (Δr internal) during balancing of the subassembly (230,520) in the clamp, wherein a turbine end portion of the shaft comprises an outer diameter approximately equal to or greater than an outer diameter of the outer race of the ball bearing cartridge; and a center housing that comprises a compressor end, a turbine end and a through bore having an axis (z g) and a turbine end opening for receiving the balanced subassembly (230, 520) as an assembled balanced unit to form clearances between the outer race of the ball bearing cartridge and the through bore, the clearances for receipt of lubricant to float the ball bearing cartridge in the through bore during operation and having a tilt angle parameter (Θ damper) as a time-varying angle between the outer race rotational axis (z OR) and the through bore axis (z g), an axial parameter (ΔZ damper) as a time-varying difference between an axial mid-point of the outer race and an axial mid-point of the through bore, and a radial parameter (Δr damper) as a time-varying difference between an outer radius of the outer race and an inner radius of the through bore. a ball bearing cartridge, wherein the ball bearing cartridge comprises an inner race having an inner race rotational axis (z IR) and an outer surface disposed at an outer surface radius (r IR,O), an outer race having an outer race rotational axis (z OR) and an inner surface disposed at an inner surface radius (r OR,I), and two sets of ball bearings (234, 234') disposed between the inner race and the outer race wherein the inner surface radius (r OR,I) of the inner surface of the outer race increases toward ends of the ball bearing cartridge;
