摘要： PROBLEM TO BE SOLVED: To provide an arrangement of preloaded rolling bearings designed to take temperature gradients into account. SOLUTION: A rolling bearing device of the type including a central shaft 11 and a hub 10 mobile in rotation relative to each other includes at least two rolling bearings 12, 13, one designated "lower" and the other designated "upper", arranged between the central shaft 11 and the hub 10 in two positions spaced in an axial direction Z. These rolling bearings are fitted with inner rings 14, 16 and outer rings 15, 17 and with balls 18, 19. The rolling bearings are assembled back-to-back or face-to-face. A rigid preload is applied to these bearings along the axial direction Z. An inner spacer 22 and an outer spacer 23 are arranged between these rolling bearings 12, 13. The inner spacer 22 and outer spacer 23 have lengths adjusted to limit variations in the rigid preload caused by temperature gradients from one point of the bearing to another, particularly thermal gradients in the radial direction.
