Abstract
A bearing system for a turbocharger shaft comprising a rotatable elongated cylinder with axially spaced journal bearing surfaces on the inside diameter and a thrust face on each end. A sleeve on the shaft incorporates a flange on one end that transmits thrust force to one thrust face on the elongated cylinder. A flanged collar on the opposite end of the shaft transmits thrust force to the thrust face on the opposite end of the elongated cylinder. A radially extending flange on one end of the elongated cylinder transmits thrust forces to stationary housings.
