According to one embodiment, a helicopter rotor system (110) has a bearing (160; 200) disposed between the drive train (112) and the rotor blade (120). The bearing comprises an elastomeric material (162; 240), a housing member (164; 210, 220) coupled to the elastomeric material, and an anti-rotation member (230) coupled to the housing member opposite the elastomeric material. A bearing mount (300) is coupled to the grip (160) and comprises a first opening (310) configured to receive the anti-rotation member of the bearing. The first opening is defined at least in part by a first surface that receives the anti-rotation member (230) and prevents the anti-rotation member from completing a rotation within the first opening.
