Railcar adapter for connecting a railcar body to a bearing providing an adapter body having two lateral channels each axially delimited by a pair of opposed lugs and a lateral surface perpendicular to the opposed lugs, each lateral channel being adapted to cooperate with the railcar body. The railcar adapter further provides swivelling means allowing swivelling of the railcar adapter relative to the railcar body.

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.

A railway vehicle and an axle box structure thereof are provided. The axle box structure includes an axle box body and a positioning node mounting seat. The axle box body includes an upper box body and a lower box body. The upper box body and the lower box body enclose a bearing mounting chamber together. A lower end surface of the upper box body has a convex portion, and an upper end surface of the lower box body has a concave portion. A first semi-circular hole and a second semi-circular hole are respectively provided at the middle of the upper box body and the lower box body. If the convex portion and the concave portion are assembled in a sealed coupling manner, the bearing mounting chamber is formed by the first semi-circular hole and the second semi-circular hole.
