Abstract

A centrifugal compressor includes a compressor housing, a motor and a rotatable shaft. A bearing housing defines a center bore that receives the shaft, and a volute assembly is positioned in the socket adjacent the bearing housing. The volute assembly has a back axial surface facing the bearing housing, stops protruding from the back axial surface. The stops abut the datum to limit tolerance stack between the bearing housing and the volute assembly. Each of the bearing housing and the volute assembly are secured to the datum.
