摘要： An aftwardly-extending internally-threaded boss of a boreless-hub compressor rotor of a turbocharger engages a corresponding externally-threaded forward end portion of an associated rotor shaft of the turbocharger, wherein an internal surface of an inner race of an associated rolling-element bearing of the turbocharger is in engagement with both an external surface of the rotor shaft and an external surface of the internally-threaded boss of the boreless-hub compressor rotor, wherein the rotor shaft extends through the inner race of the rolling-element bearing.
