An improved golf driver club head wherein each driver club head has a tensioning device which places the peripheral/outer structure of the club head in compression thereby resulting in a stronger more rigid club head structure. This is accomplished by affixing the tensioning device to the crown (top) surface of the club head and to the sole (bottom) surface of the metal head. The device is affixed to the two surfaces of the club head and is pre-tensioned. The tensioning may be accomplished by compressing the two club head surfaces together then affixing the device to the opposed surfaces so that the surfaces are held in state of relative compression. Another way this can be accomplished is to affix the device to the two club head surfaces either through a hole or boss and to adjust the device by threading, gluing or other form of fastening. In the preferred embodiment the tensioning device comprises an elongated cylindrical member having respective end members. The top and bottom surfaces of the golf club head are each provided with a cylindrical depression or recess and an aperture or passage at the lower end of the depression. The passages are just large enough to accommodate the tensioning device, but are too small to pass the respective end members. During club head manufacture, the length of the device is selected to apply a compressive force between the head surfaces. Fine adjustment is accommodated by a threaded end member. The actual compression force may be selected to yield the best performance depending on the geometry, structure and material of the club head.

Sliding contact portions on an inner surface of a bearing seat slidably support a ball head of a ball stud in a housing. Spaces between one or more of the sliding contact portions contain lubricant reserves. Load receiving portions on the outer surface of the bearing seat facing the housing also support the load placed on the ball stud. Protruding portions on the sliding contact portions decrease contact surface area and permit lubricant to cover nearly the entire ball head surface. The load receiving portions and sliding contact portions, including the protruding portions, deform to absorb repeated heavy loads while maintaining friction compensation and stable torque. The ball joint has an improved ability to compensate for dimensional tolerances, which facilitates component manufacture. The load withstanding ability, lubrication efficiency and durability of the ball joint are thus improved.
