Abstract: An end stop cap for a rolling bearing for mounting in a railway axle box of a respective support device. The cap being a concave disc delimited by a lateral wall having a symmetric axis, coaxial with a bearing's symmetric axis by an end wall, transverse to the symmetric axis, and by an elbow-shaped transition connecting the end and lateral walls. Holes extend through the end wall for fastening screws. The lateral wall terminates on the side opposite the end wall in an annular frontal surface which rests against a bearing ring. The end wall has a continuously variable thickness, in at least one radial direction passing through an symmetric axis of the holes in a radial direction between a maximum thickness located in a position substantially intermediate between an inner edge of the hole and the symmetric axis and a minimum thickness at the position of the symmetric axis.

Abstract: A sealing device for a bearing unit, where the unit has a radially outer ring, two rows of rolling bodies arranged, respectively, between the radially outer ring and a pair of radially inner rings. The sealing device further provides a spacer including an annular groove and configured to be arranged between the radially inner rings of the bearing unit and a seal housed inside the groove of the spacer. The seal is “U” shaped, defines a volume internally and is configured to be mounted in the annular groove with the concavity directed towards the axis of symmetry of the bearing unit.

Abstract: A blocking end cap for a rolling bearing in a railway axle box of a supporting device for a railway axle is provided. The cap is shaped as a concave disc delimited by an annular side wall having a symmetry axis (A), a bottom wall arranged transversely to the symmetry axis (A), and an elbow-shaped, annular joining portion, connecting the bottom wall to the side wall. The thickness of the bottom wall 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 of the cap defined by the side wall.
