Beschreibung
Zusammenfassung:	The friction bearing for supporting a journal of a cylinder of a printing press includes a bearing sleeve supported in a tubular bearing block and being manufactured with conventional machining tolerances. To minimize the radial play of the bearing, at least three axially directed cylindrical bores are provided in the annular face of the bearing sleeve and extend in the axial direction. Tapering pins are driven into respective bores to expand on discrete locations the bearing surface of the sleeve, thus minimizing the gap between the supporting bearing surfaces and the periphery of the journal. The remaining gap is larger in size than the adjusted gap and serves for conducting oil into the bearing.
