The ball member has a shaped segment providing an outer bearing surface, and the seat members include correspondly shaped inner bearing surfaces for engaging the outer bearing surface of the ball member. A slack removal mechanism is provided to urge a movable one of the seat members toward the ball member and may comprise a pressure chamber having a wall formed by a resilient diaphram positioned adjacent a pressure surface of the movable seat member, and a fitting for pressurizing this chamber with a fluid. The assembly may include a second fitting for feeding lubricant from the pressure chamber to the bearing surfaces. Optionally, a screw member may be provided for exerting an adjustable mechanical force to urge the movable seat member against the ball member.
