Abstract: A roller bearing of the type incorporating an outer and an inner race ring (1, 3) having confronting race tracks (2, 4), with lands (A, B) situated axially outside said race tracks and a number of rollers (5) being interposed between and in contact with said race tracks, said rollers (5) and race tracks (2, 4) having longitudinal section profiles of a radious of curvature, which is bigger than the distance between the outer race track and the axis of the bearing, as measured perpendicularly to the race track, which rollers (5) thereby are axially movable along the race tracks without being hindred by axial limitations at the race tracks, in order to allow relative misalignment and axial displaceability of the race tracks, wherein at least portions of the areas (A, B, G, J) of the race rings axially outside the zone (H) subjected to bearing load, have such surface finish and/or profile as to contribute in giving the rollers (5) a positive skew angle.
