A turbocharger (1) includes compressor and turbine wheels (4, 5) and a shaft (6) that connects the compressor wheel (5) to the turbine wheel (4). The shaft (6) is supported by a thrust bearing assembly (20) that includes a pair of thrust washers (42a, 42b) mounted on the shaft (6), a hollow, cylindrical spacer (80) disposed on the shaft (6) between and abutting first faces (44) of the thrust washers (42a, 42b), and a thrust bearing (100) supported on the spacer (80) between the thrust washers (42a, 42b). One of the thrust bearing (100) or the first and second thrust washers (42a, 42b) includes a copper-alloy lining (60) where the lining (60) is provided in a first region (58a) and in a second region (58b), and the remainder of the thrust bearing (100) or the first and second thrust washers (42a, 42b) is lining free. |
