Abstract
A bearing arrangement for a turbomachine includes first and second roller element bearings. The first bearing and the second bearing are disposed on opposite axial ends of an intermediate sleeve of the rotating group. The first bearing has a first inner race with a first inner radial surface and a first outer radial surface. The first inner radial surface has a first interference fit with a shaft of the rotating group. The first outer radial surface has a second interference fit with the intermediate sleeve. The second bearing has a second inner race with a second inner radial surface and a second outer radial surface. The second inner race receives the shaft with a clearance fit. The second outer radial surface has a third interference fit with the intermediate sleeve. The second inner race is coaxially aligned with the first inner race and the shaft via coaxial alignment of the intermediate sleeve and the first inner race.
