<p>PROBLEM TO BE SOLVED: To provide a cylindrical roller bearing which hardly causes the deterioration of end faces of cylindrical rollers and a raceway member even if used for supporting a rotating shaft which rotates at a high speed.SOLUTION: Mass-eccentricity cylindrical rollers 7 are arranged between an internal peripheral cylindrical raceway face 21 of an outer ring 5 and an external peripheral raceway face 32 of an inner ring 6. Gravity centers of the mass-eccentricity cylindrical rollers 7 are positioned at intervals in axial directions with respect to axial positions of the mass-eccentricity cylindrical rollers 7 which bisect axial lengths of the mass-eccentricity cylindrical rollers 7. Gravity-center existing sides of the mass-eccentricity cylindrical rollers 7 with respect to the positions for bisecting the axial lengths of the mass-eccentricity cylindrical rollers 7 are arranged at rich lubrication sides in the axial directions, and sides opposite to the gravity-center existing sides of the mass-eccentricity cylindrical rollers 7 are arranged at poor lubrication sides in the axial directions.</p> |
