A bearing arrangement for a shaft supporting a rotating tool is provided, with the shaft being rotatable on both sides of the tool at least indirectly in roller bearings, one of which can be removed for purposes of tool replacement together with an associated bearing sleeve slidable onto the free shaft end. The seating of the bearing sleeve, which is borne at least indirectly by the shaft, is formed by a conical outer surface tapering toward the shaft end. The bearing sleeve exhibit a conical borehole corresponding to the conical outer surface, and the bearing sleeve is radially expanded via a stop-limited axial shifting with respect to the conical outer surface by an amount to produce a specific level of reduced roller-bearing play.
