The invention relates to a ball roller bearing, substantially consisting of an outer bearing ring (2) having a groove-shaped track (3) and an inner bearing ring (5) have a groove-shaped track (6) and a plurality of ball rollers (9, 10), which roll between said bearing rings (2, 5) in the tracks (3, 6) and are held at regular distances from each other in the circumferential direction by a bearing cage (8) and which have a width (BK) that is dimensioned larger than the radial distance (AL) between the inside (4) and the outside (7) of the bearing rings (2, 5). The tracks (3, 6) in both bearing rings (2, 5) are divided into two track segments (3a, 3b and 6a, 6b) by an axially centered peripheral annular groove (15, 16) such that a first ball roller (9) rolls on two first diagonally opposed track segments (3a, 6b) and a second ball roller (10) rolls on two second diagonally opposed track segments (3b, 6a) of the inner and outer bearing rings (2, 5). For a simple and cost-effective production of such a ball roller
