The invention relates to a radial rolling bearing, in particular single-row spherical-roller bearing, which is composed substantially of an outer bearing ring (2) and an inner bearing ring (3) and of a plurality of spherical rollers (4), which spherical rollers (4) are arranged between said bearing rings (2,3), which spherical rollers (4) have in each case two side faces (5,6) which are flattened symmetrically from a spherical basic shape and are arranged parallel to one another, and which spherical rollers (4) are retained with uniform spacing to one another in the peripheral direction by means of a bearing cage. Here, the spherical rollers (4) have a width (bk) between their side faces (5,6) of approximately 70% of the diameter (d-k) of their spherical basic shape, and roll with their running faces (7) in two groove-shaped raceways (10,11) which are formed in the inner side (8) of the outer bearing ring (2) and in the outer side (9) of the inner bearing ring (3). According to the invention, at least one of the axial rims (12, 13, 14, 15) which delimit the groove-shaped raceways (10,11) in the bearing rings (2,3) is designed to be reduced in radial height such that the radial bearing (1) can, by means of the increased spacing (aL2) of said rim (12, 13, 14, 15) to the radially opposite rim (12, 13, 14, 15), be equipped with an increased number of spherical rollers (4) in an axial assembly process.
