The bearing 4 has an outer diameter smaller than the inner diameter of the bearing support portion 2 such that a clearance is formed between the bearing 4 and the bearing support portion 2. At an approximate center of the bearing 4 with respect to the thrust direction, a projection 19 is continuously or non-continuously formed on the inner circumferential surface of the bearing support portion 2 along a circular line centered on the motor shaft. Further, a depression 20 corresponding to the projection 19 is continuously or non-continuously formed on the outer circumferential surface of the bearing 4 along the circular line. Thus, the bearing 4 is supported within the bearing support portion 2 in such a manner that thrust movement is prevented, but slight tilting about the projection 19 is permitted.

Abstract: A process is provided for a printing form for wet offset printing. A printing style is formed on an ink-transferring surface of the printing form (12) by forming ink-absorbing and ink-repelling areas. For illustration, the ink-transferring surface is wetted with a moistening agent. The areas of the moistened surface that are to be made into ink-absorbing areas are dried in a specific manner, and a material that absorbs printing ink is uniformly applied to the ink-transferring surface with the still dry areas. It is also possible to uniformly apply to the ink-transferring surface first a flowable material that absorbs printing ink, to dry the areas to be made into ink-absorbing areas in a specific manner, and to remove it from the areas to be made into ink-repelling areas by means of moistening agent.
