Abstract
A bearing assembly for supporting rotation of a shaft in a turbocharger includes an inner race extending along an axis. The inner race is configured to be coupled to the shaft. The bearing assembly also includes an outer race spaced radially from the inner race and a cage disposed radially between the inner race and the outer race. The bearing assembly further includes a rolling element disposed radially between the outer race and the inner race. The rolling element is disposed within the cage for supporting rotation of the shaft. The outer race defines a lubricant passageway configured to direct lubricant toward the cage.
