The bearing comprises internal (2) and external (3) rings separated by two rows of rollers (1). These are retained by one or more cages (4a,4b) and run on a first spherical roller track (3a) located in the external ring. They also run on second (2a) and third (2b) tracks located in the internal ring. Stops limit the rotational movement around an axis perpendicular to the rolling axis (O). The stops are constituted by a ring (8) mounted in a circular groove (9) in the surface of the first roller track of the external ring located in a plane perpendicular to the rolling axis. The groove is located between the two rows of rollers. The external ring has a radial greasing hole (12) which intercepts the groove. The groove width is less than the greasing hole diameter. |
