Abstract
To solve heat soak and reduced heat rejection capability problems in turbochargers with rolling element bearings (REBs), the REB cartridge is mounted to the bearing housing in a way that is not rigid, thus allows for an oil damping film, but, at the same time, the REB cartridge is held both axially, to transfer thrust loads to the bearing housing, and rotationally, so that the REB cartridge does not rotate relative to the bearing housing, using male or female features in the REB and corresponding female or male features associated with the bearing bore or the turbine face of the bearing housing closure.
