Zusammenfassung:	An axle box (1) for a railway vehicle bogie comprises a rolling bearing (3) having an outer ring element (5), an inner ring element (4c), rolling elements (8) mounted there between, and a seal element (6), the inner ring element being adapted to be secured by screw bolts to an axial end (2a) of bogie axle (2). The axle box comprises an end cap (10) comprising a flange (27) with a inner face (12) and an outer face (13), an annular first radial surface portion (21) of the inner face being so defined that it is able to lean against an axial end (19) of the inner bearing ring element (4c) of the rolling bearing (3). The flange comprises a central part (22) traversed by screw bores (18). The flange (27) comprises a first inner axial ridge (15) running alongside the outer circumference of the cap (10), and extending axially towards the rolling bearing all around the flange, further than the first radial surface portion (21).
