ABSTRACT:
A thrust bearing, in particular for a turbo charger, has an essentially disc shaped bearing body (10) with a central through opening (12) for a shaft, at least one bearing surface (14) surrounding the through opening (12) for a collar which is placed on the shaft, and at least one oil supply channel which leads from a radially outer region of the bearing body to the through opening (12). In order to realize a cost effective manufacture of the thrust bearing it is proposed according to the invention that the at least one oil supply channel is designed to be a groove (16′).
