  • Bearing spacer and housing
    Patent number: 9039391
    Abstract: An exemplary center housing rotating assembly includes a turbine wheel (260); a compressor wheel (240); a center housing (210) that includes a through bore (215), extending from a compressor end to a turbine end along a bore axis, and a recess (217), adjacent the bore, in a plane orthogonal to the bore axis; a bearing assembly (230) positioned in the bore that includes a keyway (233); and an anti-rotation component (280) seated in the recess and at least partially in the keyway to restrict rotation of the bearing assembly in the bore. Various other exemplary devices, systems, methods, etc., are also disclosed.
