Abstract
A turbocharger includes a turbine, a compressor, and a bearing housing forming a bearing bore. A bearing arrangement is disposed between a shaft interconnecting the turbine and compressor wheels, and the bearing housing. The bearing arrangement includes an outer bearing race element and an inner bearing race element rotatably disposed within the outer bearing race element. The inner bearing race element forms a hollow extension extending up to the compressor wheel, the extension having a hollow cylindrical shape that surrounds a portion of the shaft that is connected on one end to the compressor wheel and at another end is disposed adjacent to a seat formed on the extension portion around the shaft, and a nut engaged on the shaft and disposed within the extension at an offset distance from the seat.
