The invention relates to a deep-rolling roller head ( 1 ) of a deep-rolling tool for deep-rolling, by means of deep-rolling-rollers ( 2 ), radii or recesses ( 3 ) on the main ( 4 ) and lifting bearing journal of a crankshaft, while the crankshaft rotates in a rotational direction ( 5 ). The deep-rolling roller head ( 1 ) has a prismatic, flat, approximately rectangular housing ( 6 ) on whose one front side ( 7 ), which faces the bearing journals ( 4 ) to be deep-rolled of the crankshaft, two roller cages ( 8, 9 ) are provided. The roller cages ( 8, 9 ) each have first front sides ( 10, 11 ), which are at a mutual distance ( 12 ) from each other and at the same time at a distance ( 13, 14 ) from the longitudinal center ( 15 ) of the housing ( 6 ). The roller cages ( 8, 9 ) have recesses ( 16 ), in which deep-rolling rollers of ( 2 ) are loosely rotatably guided in a removable manner with play. The roller cages ( 8, 9 ) are supported in each case with second front sides ( 17, 18 ) on parts of the housing ( 6 ) or on elements, which are adjustably fixed to the housing ( 6 ). The section ( 19 ) of the front side ( 7 ) of the housing ( 6 ) facing away from the rotational direction ( 5 ) has a projection ( 20 ) on which the roller cage ( 8 ) is supported with its second front side ( 17 ). An L-shaped retainer ( 22 ), which can be adjusted and fixed relative to the housing ( 6 ) is provided on the section ( 21 ) of the housing ( 6 ) facing the rotational direction ( 5 ) of the crankshaft. The second roller cage ( 9 ) is supported with its second front surface ( 18 ) on the end ( 25 ) of the long arm ( 26 ) of the retainer ( 22 ).
