Abstract
A fully or partly filled roller bearing of very small axial dimension and high loading capacity, in which the rollers are retained between two cylindrical guide and rolling tracks of an inner race and outer race of the bearing by at least one small-thickness lateral shoulder-forming ring with its inner edge of frusto-conical shape. The ring, after being expanded preferably by heating, is inserted into a corresponding annular housing groove provided in an edge of the bearing inner race. The groove has a wall of frusto-conical shape flared towards the interior of the race and a mouth of diameter slightly greater than the minimum diameter of said lateral shoulder-forming ring.
