Abstract
A turbocharger includes a main shaft carrying a turbine wheel and an impeller. The shaft is supported in a housing by means of a floating bearing and a ball bearing which is particularly effective in resisting axial loads tending to move the shaft toward the impeller. A preload spring positioned between the stationary race of the ball bearing and a thrust plate fixed to the housing provides a force urging said ball bearing against a shoulder on the main shaft against thrust forces tending to move the shaft toward the turbine wheel.
