To avoid irregularities in the construction of a bearing ring, due to which reflections occur which lead to damage to the bearing ring on the occurrence of impact loads, uneven places are avoided in the bearing ring according to the invention. A bearing ring (25) is mounted with its conical central bore (27) on a conical part (29) of the drive shaft (11) of the printing unit cylinder (3). At several places on its circumference, the part (29) of the shaft bears oil grooves (31) which are connected via bores (33) to a source of compressed oil. The bearing ring (25) is connected to the part (29) of the shaft by a retaining washer (35) and by a screw (37). By means of the source of compressed oil, the bearing ring (25) can be mounted on the part (29) of the shaft and removed again if required. <IMAGE> |
