The invention concerns a rolling burnishing roller head (1) of a rolling burnishing tool for rolling burnishing with the aid of rolling burnishing rollers (2) radii or grooves (3) on the main- (4) or lifting journal of a crankshaft, whereas the crankshaft rotates in a rotating direction (5). The rolling burnishing roller head (1) has a prismatic flat approximately rectangular housing (6) on whoseone face (7), which is oriented toward the journal (4) of the crankshaft to be roll burnished, two roller cages (8, 9) are provided. The roller cages (8, 9) each have first faces (10, 11) situated ata mutual distance (12) from one another and, at the same time, at a distance (13, 14) from the longitudinal middle (15) of the housing (6). The roller cages (8, 9) have recesses (16) in which rollingburnishing rollers (2) are rotationally guided loosely with play.; The roller cages (8, 9) are each supported via second faces (17, 18) upon portions of the housing (6) or on elements that are displaceably fastened to the housing (6). The section (19) of the face (7) of the housing (6) oriented away from the rotating direction (5) has a projection (20) on which the roller cage (8) is supported via its second face (17). An L-shaped holder (22) is provided on the section (21) of the housing (6) oriented toward the rotating direction (5) of the crankshaft. Said holder can be adjusted and fixed relative to the housing (6). The second roller cage (9) is supported on the end (25) by its long limb (26).
