Abstract: A roller bearing with symmetric barrel shaped rollers comprising an inner race (13), an outer race (14) and rollers (11), each of which rollers have at least one rounded end, and being of the bearing type where rollers and race tracks have longitudinal section profiles with substantially the same radius of curvature, whereby the rollers during normal operating conditions are axially moveable between the race tracks without hindrance from axial confinements at the race tracks for allowing relative misalignment and axial displaceability of the race tracks, wherein the end drop zone has a length (d1) which is lower than 5% of the length (1a) of the roller, and which commences where the bend of the curvature of the roller in axial direction exceeds the normal curvature of the roller by 0.1°, and where the end drop of the roller is otherwise determined by the following relations, r/1a>=0.35 for gamma values up to 0.7°, and r/1a is >=0.2 for gamma values between 0.7° and 1.4°.
