A segment rolling bearing for an axial hydraulic pump, which can be integrated in a simple way. The segment rolling bearing has an outer raceway carrier, an inner raceway carrier, a plurality of rolling bodies, and a cage. The rolling bodies are arranged in the cage such that they roll between the outer raceway carrier and the inner raceway carrier in such a way that the outer raceway carrier can be pivoted about a common pivot axis with respect to the inner raceway carrier. The cage is connected to the inner and/or to the outer raceway carrier directly and captively in at least one connecting region, at least in the radial direction with respect to the common pivot axis.

1. A segment rolling bearing, comprising: an outer raceway carrier;an inner raceway carrier, the outer raceway carrier and the inner raceway carrier being segment carriers that extend only over a circular segment;a plurality of rolling bodies arranged in circumferential succession and forming a row
1. A segment rolling bearing, comprising: an outer raceway carrier;an inner raceway carrier, the outer raceway carrier and the inner raceway carrier being segment carriers that extend only over a circular segment;a plurality of rolling bodies arranged in circumferential succession and forming a row of rolling bodies; anda cage, the rolling bodies being arranged in the cage such that the rolling bodies roll between the outer raceway carrier and the inner raceway carrier in such a way that the outer raceway carrier can be pivoted about a common pivot axis with respect to the inner raceway carrier, the cage having a first end portion and a second end portion each at a corresponding circumferential end of the row of rolling bodies that is circumferentially outside of the row of rolling bodies,wherein the cage is directly connected to at least one of the segment carriers, the direct connection being only at the first end portion and the second end portion, andwherein at a first circumferential end of the row of rolling bodies the first end portion and at least one of the segment carriers is configured to form a first radial stop to limit movement of the cage and the at least one of the segment carriers relative to one another in a radial direction and at a second circumferential end of the row of rolling bodies the second end portion and the at least one of the segment carriers is configured to form a second radial stop to limit movement of the cage and the at least one of the segment carriers relative to one another in the radial direction. 2. The segment rolling bearing according to claim 1, wherein the segment rolling bearing forms a self-supporting structural unit. 3. The segment rolling bearing according to claim 1, wherein the first radial stop comprises the first end portion, the first end portion having a first lug section, and the at least one of the segment carriers having a first undercut section, which axially receives the lug first section, and the second radial stop comprises the second end portion, the second end portion having a second lug section, and the at least one of the segment carriers having a second undercut section, which axially receives the second lug section. 4. The segment rolling bearing according to claim 3, wherein the first lug section and the second lug section extend around a rotational axis in a circumferential direction. 5. The segment rolling bearing according to claim 3, wherein the first undercut section and the second undercut section are manufactured without removal of material. 6. The segment rolling bearing according to claim 3, wherein the first lug section and the second lug section are snap-in lug sections which can be deflected in an axial section. 7. The segment roller bearing according to claim 3, further comprising a holding rim that extends radially from the at least one of the segment carriers and prevents the cage from migrating axially, the first and the second undercut sections of the at least one of the segment carriers arranged on the holding rim. 8. The segment rolling bearing according to claim 1, further comprising: a synchronizing unit which synchronizes the inner raceway carrier, the outer raceway carrier and the cage with respect to one another. 9. The segment rolling bearing according to claim 8, wherein the synchronizing unit comprises a receiving slot formed in the cage, and a control section extending into each of a first slot in the outer raceway carrier and a second slot in the inner raceway carrier, the control section being displaceable within each of the first slot and the second slot in such a way that the outer raceway carrier and the inner raceway carrier are synchronized with respect to one another. 10. The segment rolling bearing according to claim 1, wherein the cage has axial securing sections which, in an axial projection, are arranged congruently with holding rims of the inner raceway carrier and/or the outer raceway carrier. 11. An axial hydraulic pump, comprising: the segment rolling bearing according to claim 1. 12. The segment roller bearing according to claim 1, wherein at least one of the end portions is a thickened portion that has a greater thickness in a radial direction than a remainder of the cage outside of the at least one of the end portions. 13. The segment roller bearing according to claim 1, wherein the radial stops each comprise at least one of an undercut region and a lug connection. 14. A segment rolling bearing, comprising: an outer raceway carrier;an inner raceway carrier, the outer raceway carrier and the inner raceway carrier being segment carriers that extend only over a circular segment of less than or equal to 180°;a plurality of rolling bodies;a cage; anda synchronizing unit which synchronizes the inner raceway carrier, the outer raceway carrier and the cage with respect to one another,the rolling bodies being arranged in the cage such that the rolling bodies roll between the outer raceway carrier having a first guide slot and the inner raceway carrier having a second guide slot in such a way that the outer raceway carrier can be pivoted about a common pivot axis with respect to the inner raceway carrier,wherein the cage is connected to at least one of the segment carriers directly and captively in at least one connecting region, at least in a radial direction with respect to the common pivot axis, whereby the cage is held securely in the at least one of the segment carriers during mounting of the segment rolling bearing,wherein the cage has an elongate slot, in which a control section is mounted displaceably, the control section comprising an outer end section and an inner end section, the outer end section and the inner end section slidingly arranged within the first guide slot and the second guide slot, respectively, in such a way that the outer raceway carrier and the inner raceway carrier are synchronized with respect to one another, andwherein the control section is formed by a rotationally symmetrical control pin with a center region having a greater diameter than the outer end section and the inner end section.
