An aircraft rotor assembly (104) has a yoke (110) defining a plurality of bearing pockets (114). Each bearing pocket houses an axisymmetric elastomeric spherical bearing (116) at least partially therein. The axisymmetric elastomeric spherical bearings (116) comprise flap, lead-lag, and pitch hinges for rotor blades (106) coupled thereto. The rotor blades (106) maintain a first in-lane frequency of less than 1/rev through the use of damper assemblies (142) coupled between adjacent blades (106).
