A bearing housing assembly for a turbocharger, said bearing housing assembly comprising:

• a bearing housing extending along an axis and having,
• a cross-bore surface extending along said axis and defining a cross-bore to receive a lubricant,
• a feed groove surface defining a feed groove in fluid communication with said cross-bore and having,
• a constant radial portion extending circumferentially about a majority of said axis and having a first groove radius that is constant along said majority of said axis, and
• an expanded radial portion extending from said constant radial portion circumferentially about said axis and having a second groove radius larger than said first groove radius, and
• an interior surface having an interior radius smaller than said first groove radius, with said interior surface defining an interior in fluid communication with said feed groove;
• and
• a bearing assembly disposed in said interior of said bearing housing, said bearing assembly including,
• an outer race extending along said axis and having a receiving groove surface defining a receiving groove in fluid communication with said feed groove;
• and
• an inner race spaced radially inwardly from said outer race;
• and
• a rolling element disposed between said outer race and said inner race.
