Abstract
An exemplary housing for a rotor of a turbocharger includes a bore, defined at least in part by the housing; a pair of rotor limiting surfaces positioned at a first diameter, one rotor limiting surface positioned proximate to a turbine end of the housing and the other rotor limiting surface positioned proximate to a compressor end of the housing; a rotor damping surface positioned at a second diameter, intermediate the pair of rotor limiting surfaces; and an opening to receive a pin to axially locate a squeeze film bearing cartridge in the bore of the housing. Various exemplary bearing cartridges, housings, assemblies, etc., are also disclosed.
