Abstract
A bearing system for a turbocharger, simple in design and easy to manufacture, having desired rotational dynamics of a three piece bearing design, yet having the superior vibration damping characteristics of a one piece bearing design. The inboard end of each journal bearing includes an axial recess for receiving an outboard end of a cylindrical bearing spacer, thereby axially locating the journal bearings as well as axially and radially locating the bearing spacer.
