A rotor assembly (11) for a rotary-wing aircraft, the rotor having a central hub assembly with a flexure-type, twist-shank yoke with multiple arms (19), each arm (19) being adapted for a rotor blade to be mounted thereto. The arms (19) provide for pitch changes of blades (15) attached to the yoke through twisting of portions of the arms about a corresponding pitch axis. An inboard pitch bearing (37) associated with each arm (19) is attached to the hub assembly and allows for rotation of the attached blade about the pitch axis, the inboard pitch bearing (37) also allowing for out-of-plane motion of the arm relative to the hub assembly about a flapping axis. An outboard pitch bearing (35) associated with each arm is attached to the associated arm a selected distance from the inboard pitch bearing and allows for rotation of the attached blade about the pitch axis.
