A radial-axial roller bearing, having an inner ring (5), coaxially with which an outer ring (4) is disposed, between which rolling bodies (15) roll in order to absorb radial forces, and having cylindrical rolling bodies (17, 18) disposed in cages (19, 20, 24, 25) on both sides to absorb lateral forces, the tracks of which are formed on one side by the end faces of the outer ring (4) and on the other side by a runner plate (8, 9) in each case. The inner ring (5) is formed from two part-rings (6, 7), which are integrally connected to the runner plates (8, 9), a separating plane (14) being placed between the part-rings (6, 7) in the track region of the radial bearing (1). In this manner, a compact, tilt-resistant bearing unit is formed.

The radial-axial roller bearing as claimed in claim 1, characterized in that the separating plane (14) is placed in the center of the track region of the radial bearing (1). 3. The radial-axial roller bearing as claimed in claim 1, characterized in that the inner ring (5) is initially machined as a one-piece component and is split into the two part-rings (6, 7) after its production. 4. The radial-axial roller bearing as claimed in claim 1, characterized in that the part-rings (6, 7) are retained one upon the other by fixing screws. 5. The radial-axial roller bearing as claimed in claim 1, characterized in that the cylindrical rolling bodies (17, 18) of the axial bearings (2, 3) are each guided by a rim (22, 23) which is disposed either on the outer ring (4) or on the runner plates (8, 9). 6. The radial-axial roller bearing as claimed in claim 5, characterized in that the cage of the axial bearings (2, 3) is composed of individual segments (26) abutting one another in the peripheral direction and each receiving a cylindrical rolling body (17, 18). 7. The radial-axial roller bearing as claimed in claim 6, characterized in that the segments (26) each have in at least one part-region of their radial extent an arcuate line of limitation (27, 28) lying opposite one another in the peripheral direction in a manner such that a contact point (29) is formed between two neighboring segments (26) and is disposed in the region between the part-circular line and the rim (22, 23). 8. The radial-axial roller bearing as claimed in claim 6, characterized in that a spring means is disposed between two neighboring segments (26). 9. The radial-axial roller bearing as claimed in claim 6, characterized in that the segments (26) each comprise, on their radially inward sides, two protuberances (30, 31) which are mutually spaced in the peripheral direction.
