Abstract
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.
