The invention relates to a multi-row roller bearing which comprises at least one pair of rows of rolling elements (10a, 10b) arranged in X alignment, the two rolling element rows (6, 7; 8, 9) of the at least one pair of rows having the same number of rolling elements and the same rotational speed about the longitudinal axis of the roller bearing. The rolling elements (10a, 10b) of the pair of rows roll off on a rimless outer bearing ring (1, 2, 3) and on a rimless inner bearing ring (4, 5). The rolling elements (10a, 10b) have respective axial throughbores (11) and a common fixing pin (12) which is bent in its center to match the X alignment of the rolling elements (10a, 10b) of the pair of rows extends through axially adjacent rolling elements (10a, 10b). A rotationally symmetric spacer element (15) having contact surfaces (16) that are convex in relation to the axial direction is arranged between the two axially adjacent rolling elements (10a, 10b), the fixing pin likewise extending therethrough, thereby resulting in an improved axial force transmission and mutual guidance of the rolling elements (10a, 10b). |
