There is disclosed a ball cup for a ball bearing with a shaft and with a hollow space for the reception of a ball head accessible by way of an entrance opening, in the case of which at a distance from the wall of the hollow space at least two slits are provided symmetrically in relation to the hollow space and essentially in longitudinal direction of the shaft in such a way that in the case of the introduction of the ball head through the introducing opening into the hollow space, the bridges located between the wall of the hollow space and the slits may be shifted to the outside in a radial direction based on the bridges narrowing the entrance opening and that they will again shift in a radial direction inward after introduction of the ball head into the hollow space. The bridges are developed as an annular restriction disposed symmetrically to the hollow space and they comprise the slits, the annular restriction and the hollow space essentially centrically so far and are disposed at such a distance from the annular restriction, that the bridges on the basis of their strength have a flexibility absorbing the extension of the annular restriction in radial direction transversely to the direction of the shaft as well as along the direction of the shaft.
