Furthermore, advantageously, the hardening process of the non-concave areas, that is, for example, the load-bearing areas, of the ball track can be optimized, since only the areas raised relative to the concave areas have to be hardened in order to ensure an optimal joint function. As a result, the longevity in particular of the ball track or the ball tracks in the

- the at least one web comprises a concave portion.
- the web is a ball track.
- an additional fat pocket or additional fat pockets are provided in the ball track in an advantageous manner.
- Providing additional grease or lubricant in the grease pockets in the ball track can thus improve the lubrication between balls and outer joint part and the friction between balls and outer joint part can be reduced. Furthermore, advantageously, the hardening process of the non-concave areas, that is, for example, the load-bearing areas, of the ball track can be optimized, since only the areas raised relative to the concave areas have to be hardened in order to ensure an optimal joint function. As a result, the longevity of the particular
- Ball track or the ball tracks increased in the outer joint part.
- the web is a cage web.
- This advantageously provides additional pockets of fat in the cage track.
- the lubrication between the cage and the outer joint part can thus be improved or the friction between the cage and the outer joint part can be reduced.
- Another object of the present invention is a tool for producing an outer joint part by means of flow-forming, in particular with the invention
- the tool comprises a contour mandrel for opposite the contour mandrel against rotation receiving a blank, wherein the tool comprises a drive for driving the contour mandrel such that the blank and the contour mandrel in
