ABSTRACT:
A method is disclosed for forming an annular collar (11) that is essentially radial on the hollow annular end portion (12) of a port (7). This method has the following steps: A. radially deforming the end portion (12) by means of a first tool (16), in which the axis (18) of the tool (16) and the axis (5) of the end portion (12) form a non-zero angle α between them to obtain an essentially radial collar preform (17); and B. deforming this preform (17) by means of a second tool (23) to obtain a final shaping of the collar (11) by pressing. This invention also relates to a method of retaining a bearing (1) on a shaft (7), and to the assembly that comprises this shaft (7) and bearing (1).
