A centrifugal force (CF) bearing for a rotorcraft rotor assembly includes an inner-member, an outer-member, and an elastic member interposed between the inner- and outer-members. The inner-member includes a boss configured for location to and engagement with a yoke. The boss includes a tapered profile (e.g., conic) portion. A tapered recess region of the yoke includes a profile that is substantially matched to receive and contact the tapered profile of the boss. The CF bearing is configured for attachment to a grip of the rotor assembly. The boss is configured to communicate mechanical loads (e.g., centrifugal force, lateral shear, vertical shear) from the grip to the yoke during operation of the rotor assembly.
