ABSTRACT:
A thrust bearing arrangement for a turbocharger including a thrust bearing unit having separate normal and reverse thrust bearings, and a thrust member provided on a turbine shaft and interposed between the normal and reverse thrust bearings. Both the normal and reverse thrust bearings are spaced from the turbine shaft in a radial direction of the turbine shaft and a lubrication oil is supplied to a first contact area between the normal thrust bearing and the thrust member. An oil guide portion is formed on a bearing housing for further supplying the lubrication oil to a second contact area between the thrust member and the reverse thrust bearing. A seal member is provided on the turbine shaft in slidable contact with an inner peripheral face of the normal thrust bearing.
