Abstract: A constant velocity fixed ball joint 11 having a longitudinal axis A and comprising an outer joint part 12 with an annular member 13 and a joint base 14 which is produced separately from and is connected to, the annular member 13, an inner joint part 23 which is axially supported at least indirectly on the joint base 14 of the outer joint part 12, first ball tracks 22 in the outer joint part 12 and second ball tracks 25 in the inner joint part 23 which first ball tracks and second ball tracks are positioned in planes extending through the longitudinal axis A and comprise curved centre lines, balls 16 which run in pairs of first ball tracks 22 and second ball tracks 25 associated with one another, a cage 17 which comprises circumferentially distributed cage windows 18 for receiving balls 16 and which hold said balls 16 in a common plane. The cage 17 is axially form-fittingly held in both directions in an inner face in the outer joint part 12.
