In a roller bearing, surface layers are formed on the inner surfaces of flanges which confront with the end faces of cylindrical rollers. The surface layers contain solid lubricant. The end faces of the cylindrical rollers are brought into slide contact with the surface layers. Hence, even when the roller bearing is insufficiently lubricated, the temperature rise is effectively suppressed, thus being free from the occurrence of seizure.
