Abstract
A multiple-row ball bearing arrangement, which has at least one inner bearing ring and at least one outer bearing ring which are coaxially disposed on a longitudinal axis. The multiple-row ball bearing arrangement also has a plurality of balls disposed between the inner and the outer bearing rings in at least one first ball row and a second ball row adjacent to the first ball row, and a first cage for guiding the balls of the first ball row and a second cage for guiding the balls of the second ball row. The first and the second cage each have a first and a second cage side ring. The first cage side ring of the first cage and the second cage side ring of the second cage are adjacent to each other and, at least in some sections, are arranged so as to overlap along the longitudinal axis.

A multiple-row ball bearing arrangement, comprising:
- at least one inner bearing ring;
- at least one outer bearing ring, which is arranged coaxially to the inner bearing ring on a longitudinal axis;
- a plurality of balls, which are arranged between the inner bearing ring and the outer hearing ring in at least one first ball row and one second ball row, which is adjacent the first ball row;
- a first cage for guiding the balls of the first ball row;
- and
- a second cage for guiding the balls of the second ball row,
- wherein the first cage and the second cage each have a first cage side ring and a second cage side ring, and
- wherein the first cage side ring of the first cage and the second cage side ring of the second cage are adjacent each other and are arranged so as to overlap at least in sections along the longitudinal axis.
A single-row or multiple-row ball bearing arrangement, comprising;
- at least one inner bearing ring;
- at least one outer bearing ring, which is arranged coaxially to the inner bearing ring on a longitudinal axis;
- a plurality of balls, which are arranged between the at least one inner bearing ring and the outer bearing ring in at least one ball row;
- at least one cage for guiding the balls, the cage having a first cage side ring, a second cage side ring, a plurality of webs, which connect the first cage side ring and the second cage side ring to form pockets for accommodating the balls, the pockets being defined by two adjacent webs, one circumferential section of the first cage side ring and one circumferential section of the second cage side ring, the circumferential section of the first cage side ring and the circumferential section of the second cage side ring of the cage are arranged completely on different sides of a graduated circle surface of the ball row associated with the cage and do not touch the graduated circle surface;
- and
- a three-point snap-type device for holding the balls in the pockets provided in a region of a pockets of the cage, the three-point snap-type device being formed by two points of the first cage side ring and by one point of the second cage side ring, and the three-point snap-type device allowing the balls to be inserted into the pocket through resilient deforming in the region of the two points of the first cage side ring and of the one point of the second cage side ring.
