The aim of the invention is to pre-stress a tapered roller bearing (1) fixed with a conical seat to a tapering roller journal (3) of rollers (2), especially supporting rollers, arranged in a roll stand by means of chocks (4), by subjecting the same to hydraulic pressure. To this end, the inner bearing ring (18), the rollers (17), and the outer bearing ring (13) of the tapered roller bearing (1) are subjected to pressure created during the milling and are pre-stressed against the roller (2). A ring-type pressure exerting device (5) is supported on the roller (2) by means of an axial bearing (9) provided on a roller end journal (8), is arranged against the outer ring (13) of the tapered roller bearing (1), and when subjected to pressure, displaces the chock (4) with the outer ring (13) of the bearing in the direction of the roller table (15), or displaces the roller (2) in the opposite direction. |
