An articulated coupling male connection member support assembly having an improved lubrication arrangement incorporated therein. Such support assembly includes a bottom ring bearing member supported on an upper surface of a bottom wall portion of a female connection member adjacent an outer end thereof. The bottom ring bearing member has a concave shaped spherical upper surface. An upper ring bearing member having a convex shaped spherical bottom surface is supported by such concave upper surface of the bottom ring bearing member. The upper ring bearing member has a substantially flat upper surface for supporting a bottom surface of a male connection member adjacent an outer end thereof. There is a substantially solid lubricating liner member disposed between such concave shaped spherical upper surface of the bottom ring bearing member and such convex shaped spherical bottom surface of the upper ring bearing member. This substantially solid lubricating liner member is secured to one of such concave shaped spherical upper surface and such convex shaped spherical bottom surface.
