A roller bearing (10) includes a plurality of bearing rollers (12) located between confronting bearing surfaces (16, 19), the bearing surfaces being rotatable one relative to the other about the rotational axis of the bearing, and the bearing including biasing elements (18) which provides a force acting in a direction between the confronting bearing surfaces (16, 19) whereby, under all load conditions for which the bearing is designed for use, each bearing roller is retained in contact with each of the confronting bearing surfaces.
