PROBLEM TO BE SOLVED: To provide a method for manufacturing essentially radial annular collar on a hollow annular end of a part. SOLUTION: The manufacturing method includes a deformation step for obtaining a collar preform 23 with a radial part 23b and a step for extending the preform 23 by pressing to obtain the final shape of the collar. During the deformation, an intermediate portion 23e on the free side surface of the radial part 23b is inclined by a non-zero angleβwith respect to the perpendicular to the axis 5. During the expansion, moreover, at least an end area of the intermediate portion 23e is inclined by an angleδwith respect to the perpendicular to the axis 5. The angleδis surely greater than the angleβ. The invention also concerns a method for holding a bearing 1 on a shaft 7, and an assembly equipped with the bearing 1 and the shaft 7.
