In this joint, the inner element (3) and the outer element (2) are equipped with first outer rolling grooves (6) and with first inner rolling grooves (8), as well as with second outer rolling grooves (7) and with second inner rolling grooves (9), which are shaped without an undercut starting respectively from the two open sides (10, 11; 12, 18). In order to obtain conditions under which the cage (4) is guided, the angle beta for controlling the cage is always greater than 7 DEG . It is not necessary for the cage (4) to be guided by the outer element (2) or by the inner element (3).
