ABSTRACT:
A radial anti friction bearing (1) which is configured as a single-row spherical roller bearing, which includes an outer bearing ring (2), an inner bearing ring (3) and a plurality of spherical rollers (5) that are arranged between the bearing rings (2, 3). The spherical rollers have respectively two side faces (6, 7) which are flattened symmetrically from a spherical base shape, are retained with uniform spacing to each other a bearing cage (4) and roll with their running faces (8) in two groove-shaped raceways (11, 12) which are defined, respectively, by two axial rims (13, 14and15, 16). The width (bK) of the spherical rollers (5) between their side faces (6, 7) is smaller than the distance (aB) between the radially opposing axial rims (13, 15and14, 16), such that the spherical rollers (5) can be in the space therebetween via the axial mounting method in the radial anti friction bearing. The radial anti-friction bearing (1) has an increased axial load capacity suitable for variable axial loads at a operational pressure angle (α) of up to20° on both sides of the bearing longitudinal axis (17), in which the raceways (11, 12) in both bearing grooves (2, 3) are formed with an increased depth (tLA, tLI) and width (bLA, bLI) and the spherical rollers (5) have a width (bK) between their side surfaces (6, 7) which is arranged to the operational pressure angle (α) at20°.
