The invention relates to a bearing arrangement for journalling a device, in particular a doctor blade carrier, which is designed to be able to move axially in an oscillating fashion as well as to be moved a certain angle about its axis from an OFF position, the rest position of the device, to an ON position, the working position of the device, and back. The invention is characterized by comprising a bearing housing (9) containing a hydraulic cylinder (34) having two pressure chambers to accomplish the axial oscillations, viz a first pressure chamber (35) axially outside the end of the journal (5) and a second, annular, pressure chamber (39) around the journal at a distance from its end, first and second connecting conduits (41, 42) to deliver and evacuate a pulsating flow of hydraulic fluid to alternately said first and second pressure chambers, respectively, to accomplish the axial oscillations, and a hydraulically powered turning device (50) inside the bearing housing with which to turn the journal in the hydraulic cylinders (34) to and from said on and off positions. |
