Roller bearing incorporating a number of rollers (6) provided between and in contact with two race tracks (3, 5), whereby the rollers and the race tracks have longitudinal section profiles with substantially the same radius of curvature (R), and where the radius of curvature (R) is bigger than the distance between the outer race track and the axis of the bearing, measured perpendicularly against the race track, whereby the rollers (6) are axially movable between the race tracks without obstructions from axial limitations at the race tracks for permitting relative misalignment and axial displaceability of the race tracks, which are only limited by the radial squeezing of the rollers between the race tracks, wherein the relation between the radius of curvature (R) of the roller profile and the length of the roller (1a) is R/1a < 20. |
