an outer bearing ring;
an inner bearing ring disposed radially inward of the outer bearing ring and having a second inner diameter; and,
a connection part disposed at least partially radially outward of the outer bearing ring and at least partially radially inward of the planetary carrier, wherein:
the first inner diameter is smaller than the second inner diameter.
2. The planetary gear as recited in claim 1 , wherein the inner bearing ring is swaged.
3. The planetary gear as recited in claim 1 , wherein the inner bearing ring has an axially projecting collar portion, which can be brought into contact with the first sun gear.
4. The planetary gear as recited in claim 1 , wherein the planetary carrier has an axially projecting collar portion, which can be brought into contact with the first sun gear.
5. The planetary gear as recited in claim 1 , wherein the outer bearing ring is formed as a one-piece cold-formed part with a raceway for a rolling body.
6. The planetary gear as recited in claim 1 , wherein the planetary carrier extends radially further inwards than the inner bearing ring.
7. The planetary gear as recited in claim 1 , wherein the planetary gear is designed as a spur wheel differential.
8. The planetary gear as recited in claim 7 , wherein a friction disc is located between the first and second sun gears.
9. The planetary gear as recited in claim 1 , wherein the outer bearing ring is connected material-wise with the planetary carrier.
10. The planetary gear as recited in claim 1 , wherein the outer bearing ring is connected shape-wise with the planetary carrier.
11. The planetary gear as recited in claim 1 , wherein the outer bearing ring is connected force-fitting-wise with the planetary carrier.
12. The planetary gear as recited in claim 1 , wherein the connection part connects the planetary carrier with the rolling bearing and is deep-drawn.
13. A planetary gear, comprising:
an axis of rotation;
a planetary carrier rotatable about the axis of rotation;
