摘要

Radial rolling bearing (1) comprises a guiding board (10) arranged on the track (6) of the inner bearing ring (3) and a diagonally lying guiding board (8) arranged on the track (5) of the outer bearing ring (2) each radially over the partial circular diameter of the radial rolling bearing. The guiding boards each have annular contact surfaces (11, 12) in the region of the partial circular diameter on their inner sides. Preferred Features: The annular contact surfaces are formed on the lengthened guiding boards of the bearing rings preferably by axial annular recesses (13, 14) in the inner sides of the guiding boards.
