A rotor arm assembly (226) for use in a rotorcraft (200) rotor hub system (208) includes a pitch shaft (252) and a plurality of discrete bearings (240, 246, 248) coupled to the pitch shaft (252). The plurality of bearings are elastomeric bearings configured to facilitate movement of the rotor arm assembly (226) about a plurality of degrees of freedom. A respective one of the plurality of bearings (240, 246, 248) is configured to accommodate a single degree of freedom.
