Abstract
A turbocharger using a high speed rolling element bearing system is improved in desired speed and life by providing an insulating spacer, with a thermal conductivity lower than that of the material in the inner race of the REB, between the turbine-end of the inner race of the bearing system and the compressor-end face of the piston ring boss to impede the flow of heat from the turbine wheel to the inner race of the rolling element bearing.
