A bearing system for a turbocharger shaft includes an elongated bearing carrier with two anti-friction ball bearings mounted in its ends and with a radially extending flange at one end that cooperates with stationary housing portions and carries thrust loads of the rotor in both directions. The elongated bearing carrier is supported within the housing by axially spaced elastic supports which permit the rotating assembly to rotate about its mass center and provide a shock and vibration cushion. The elongated bearing carrier and housing cooperate to provid...


The invention claimed is: 1. In a bearing system for a rotating assembly carried by a housing of a turbocharger for an internal combustion engine, the improvement wherein the bearing system and housing combine to form a coolant cavity by a removable elongated bearing carrier whose outer surface forms one surface defining the coolant cavity and is sealed with said housing by an elastomeric band on each side of said one surface, said elastomeric bands also carrying and cushioning the bearing system and rotating assembly from shock and vibration loads; sai...
