A bearing has an inner race (20) an outer race (21) and rollers (22) in a cage (23) therebetween. To prevent skidding of the rollers at high speeds of rotation of the bearing, the inner race is provided with auxiliary bearing tracks (26,27) which are radially movable under centrifugal loads on loading segments (30,31) disposed beneath the tracks. <IMAGE> |
