Abstract
A turbocharger bearing assembly can include a spacer that includes an axial through bore, a compressor side surface and a turbine side surface; a compressor side rolling element bearing that includes an outer race surface that faces the compressor side surface of the spacer; a turbine side rolling element bearing that includes an outer race surface that faces the turbine side surface of the spacer; and a spring seated between a first end cap disposed at least in part in the axial through bore of the spacer and a second end cap disposed at least in part in the axial through bore of the spacer where the spring biases an axially facing surface of the first end cap against the outer race surface of the compressor side rolling element bearing and where the spring biases an axially facing surface of the second end cap against the outer race surface of the turbine side rolling element bearing.
