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 first and second bearings formed between an outer bearing race element disposed within the bearing bore an inner bearing race element disposed within the outer bearing race element and between the outer bearing race element and the shaft. The inner bearing race element includes a flared portion extending radially outwardly to provide torsional and bending rigidity to the shaft.
