Turbocharger center housing and rotating assembly

摘要

An exemplary center housing (510) for a turbocharger includes a compressor end and a turbine end and a through bore that includes a turbine end opening for receiving a bearing cartridge (230) and shaft subassembly (520). In an assembly, a turbine end shaft portion of the subassembly can have an outer diameter approximately equal to or greater than an outer diameter of the bearing cartridge (230). The turbine end shaft portion can include grooves (225,227) where each groove is configured to seat a seal ring.
