Abstract: An assembly for providing flexure to a blade of a rotary blade system, the assembly including an upper support plate (22) having an upper curved surface (37) , a lower support plate (24) having a lower curved surface (37) , and a yoke (120) positioned therebetween. At least one of the upper and lower yoke surfaces (37) having a layer of cushioning material (56) positioned thereon and secured thereto. The layer of cushioning material (56) extending along and following the general contour of yoke surface (37) , and the layer of cushioning material (56) directly contacting a support plate (22,24) . Another embodiment is an assembly for providing flexure to a blade of a rotary blade system, including, an upper support plate (22) having an upper curved surface (27) , a lower support plate (24) having a lower curved surface (37) , and a yoke (120) positioned therebetween and directly contacting the support plates wherein one of the curved surfaces (37) is a non-circular arc that does not form part of the circumference of a circle.
