A soft-in-plane proprotor system (100) for a tiltrotor aircraft (10) having a helicopter mode and an airplane mode. The proprotor system (100) includes a hub (102), a plurality of proprotor blades (104) and a plurality of loop yokes (120), each coupling one of the proprotor blades (104) with the hub (102) and each including first (204) and second (206) longitudinal sections extending between inboard (208) and outboard (210) arcuate sections and a bearing assembly (118) disposed between the inboard (208) and outboard (210) arcuate sections of each loop yoke (120). Each bearing assembly (118) includes a flapping bearing (122) disposed generally within the inboard arcuate section (208) of the respective loop yoke (120) and coupled to the hub (102), a lead-lag damper (128) coupled to the hub (108), a centrifugal force bearing (138) disposed generally within the outboard arcuate section (210) of the respective loop yoke (120) and a blade anchor (130) coupled between the lead-lag damper (128) and the centrifugal force bearing (138). The blade anchor (130) is also coupled to the respective proprotor blade (104).
