摘要

The anti-friction bearing comprises first (1) and second (2) rings, each of which has a groove between two walls. Roller bearings (5) are mounted between these whose contact surface(S) with the rings is limited by a curved bus line (Y) when it rotates about its axis (X). Each bearing contacts the rings at its ends and they are mounted so that they cross in the middle.
