Zinc alloy link ball joint RBI (SQZ) series is inline design, housing is made of high-strength zinc alloy, the mounting bolt and the housing are arranged on the same axis, allowing to receive both a compressive load and a pulling load. Since grease in contained in the boot, this model achieves high lubricity and high wear-resistance. A highly accurate bearing steel ball used in the spherical area is first encased in the housing by die cast molding, and then is specially welded with the shank. This unique process enables the mirror surface of the steel ball to be transferred or duplicated on the spherical surface inside the housing to ensure full contact between the ball and the socket. Equipped with a boot for protection against muddy water. Use of a boot with high trackability in the ball shank prevents muddy water from entering the spherical area even in a muddy atmosphere. Accordingly, those types equipped with boots are used also in outdoor applications and automobile parts under the chassis.
