A blocking end cap (11) for a rolling bearing in a railway axle box of a supporting device for a railway axle (2); the cap is shaped as a concave disc delimited by an annular side wall (13) having a symmetry axis (A), a bottom wall (14) arranged transversely to the symmetry axis (A), and an elbow-shaped, annular joining portion (15), connecting the bottom wall (14) to the side wall (13); the thickness of the bottom wall (14) measured in a direction parallel to the symmetry axis (A) is continuously variable in the radial direction between a maximum (S1) situated at the symmetry axis (A) and a minimum (S2) arranged at a radially outer edge (18) of the cap (11) defined by the side wall (13). |
