Abstract
A turbocharger uses a high speed rolling element bearing system. An exemplary rolling element bearing system includes a polymer sleeve to impede the flow of heat from the bearing housing into the outer race of the rolling element bearing system. In a second embodiment of the invention, the sleeve is supported by an oil film. In a third embodiment of the invention, the bearing cartridge is damped by a damping medium which also connects the bearing cartridge to the bearing housing.
