A rotor hub provides transfer of centrifugal force while permitting angular motion about a pitch axis, having an outer member and an enveloped concentric inner member with a hollow end part, the two members joined by two spaced radial bearings and each having two diametrically opposed windows that are aligned such that a beam transverse to the pitch axis passes through all four windows, transferring the centrifugal force from the outer member through a small elastomeric thrust bearing within the hollow part to an end cap of the inner member.
