A rotor hub assembly (12) for a rotorcraft (10) includes a yoke (202) forming a bearing bore (218). The yoke (202) has a teetering axis (230) extending through the bearing bore (218). The rotor hub assembly (12) includes a flapping bearing (232) disposed in the bearing bore (218). The flapping bearing (232) is operable to regulate teetering of the yoke (202) about the teetering axis (230). The rotor hub assembly (12) includes an axial spring (248, 250) abutting the flapping, thereby reducing movement of the flapping bearing (232) along the teetering axis (230).
