rolled tube production, namely arresting and regulating mechanisms of cross screw rolling mills. SUBSTANCE: mechanism includes frame, arresting head mounted in frame and hinged by means of drive unit (in body and in end cover of head there are water- and lubricant-supplying ducts), spindle mounted in radial bearings and in thrust bearing, cavities between sealing units and radial bearings, cavity for lubricating between thrust and terminal radial bearings; arresting lock. In body of arresting head there are additional ducts for lubricant connecting cavities arranged between sealing units and radial bearings with cavity for supplying lubricant. EFFECT: possibility for continuous lubrication of bearings, their increased useful life period, enhanced efficiency of mill. 3 dwg
