A constant velocity twin ball joint, having an outer joint part with outer ball tracks, an inner joint part with inner ball tracks. Circumferentially adjoining pairs of tracks comprise center lines of the outer and inner ball tracks which, when the longitudinal axes are aligned, are positioned in planes which extend parallel relative to one another and are symmetric relative to the longitudinal axes. A ball cage is positioned between the outer joint part and the inner joint part and comprises circumferentially distributed cage windows which each accommodate pairs of balls of adjoining pairs of tracks positioned in parallel planes. The circumferential length of second cage windows for second pairs of balls is smaller than the circumferential length of first cage windows for first pairs of balls.
