An aircraft rotor assembly has a yoke defining a plurality of bearing pockets. Each bearing pocket houses an axisymmetric elastomeric spherical bearing at least partially therein. The axisymmetric elastomeric spherical bearings comprise flap, lead-lag, and pitch hinges for rotor blades coupled thereto. The rotor blades maintain a first in-lane frequency of less than 1/rev through the use of damper assemblies coupled between adjacent blades.
