Title: Flexible bearing having low torque resistance

Abstract: A flexible bearing is constructed of layers of elastomer and rigid material, alternately stacked and bonded together. The central portion of each elastomeric layer, however, is an elastomeric material having a lower elastic shear modulus than that of the edge portions. This lowers the resistance of the bearing to forces exerted on it in directions parallel to the layers of elastomer and rigid material.
