The present invention relates to a sliding ball-type constant-velocity joint for vehicles, which enables two groups of balls having different pitch circle radii (PCR) to be arranged alternately and cancel out ball component forces caused by vibrations, and can reduce idle vibrations when applied to an automatic transmission vehicle. The present invention includes the following components: an outer race which is rotated by receiving rotational power of an engine, and where a groove used as a track groove is formed at the inside; an inner race installed at the inside of the outer race; multiple balls which are divided into two groups having different pitch circle radii (PCR) and arranged alternately, and deliver rotational power of the outer race to the inner race; and a cage to support the balls. |
