Claim 15:
16. A method for bearing a shaft of an exhaust turbocharger comprising a modular bearing that includes a bearing assembly module arranged between a compressor and a turbine of the exhaust turbocharger, wherein the modular bearing is inserted in a bearing housing with a receiving chamber, wherein the receiving chamber has a step including a stop surface running substantially in a radial direction of the exhaust turbocharger, wherein the stop surface faces the compressor and defines an axial stop for the bearing assembly module installed on a compressor side, and wherein the step divides the receiving chamber into (i) a first receiving chamber section arranged on the compressor side and (ii) a second receiving chamber section arranged on a turbine side, the method comprising:
selecting the bearing assembly module from a set of bearing assembly modules comprising a bearing assembly module having a rolling bearing and a bearing assembly module having a plain bearing, wherein both bearing assembly modules of the set of bearing assembly modules can be installed in the receiving chamber interchangeably, and can be removed from the receiving chamber without being destroyed, wherein each bearing assembly module defines one or more ducts on the compressor side of the bearing assembly module, and wherein the receiving chamber has an interface which is designed for making contact with a bearing flange of either bearing assembly module installed in the receiving chamber and for connecting an oil duct guided through the bearing housing to the one or more oil ducts which are guided through the bearing flange and
installing the selected bearing assembly module in the receiving chamber, wherein the first receiving chamber section receives an additional thrust bearing when the selected bearing assembly module is the bearing assembly module having the plain bearing, wherein the one or more oil ducts are connected to the duct defined in the bearing housing, and wherein the one or more ducts defined in the installed bearing assembly module are positioned within the first receiving chamber section of the exhaust turbocharger.
