ABSTRACT:
The rotating components of an exhaust gas driven turbocharger are supported by a pair of axially separated ball bearings having an outer race and an inner race. A spacer between the bearings engages the outer race of both bearings and exerts a preload bias on the outer races of the bearings urging the outer races away from one another. Accordingly the bearings are preloaded so that centrifugal forces generated during high speed operation will not force the ball bearing away from the inner races.
