Abstract

A counter track joint having an outer joint part (10), inner joint part (20), a ball cage (30) and torque transmitting balls. First outer tracks and first inner tracks form first pairs of tracks which widen in a first direction, and second outer tracks and second inner tracks form second pairs of tracks which widen in an opposed second direction. The annular cage (30) includes four first and four second circumferentially distributed cage windows which each accommodate one of the balls and which hold the balls in one plane. The second outer ball tracks (12), at one end, include widened, non-contacting assembly portions (13) for inserting balls (32) into the second cage windows from the radial outside, with all the first cage windows already having balls, and with the second cage windows axially projecting from the outer joint part (10) as a result of the joint being over-articulated.
