Claim:
1. A rolling bearing comprising: a first ring; a second ring; at least one row of rolling elements disposed radially between the first ring and the second ring; a sealing flange mounted in a manner to bear axially against a front surface of the first ring, the sealing flange comprising a mounting portion that extends radially between a radially inner edge and a radially outer edge, the mounting portion further comprising an axially inner, radially extending surface and an axially outer, radially extending surface that each extend between the radially inner edge and the radially outer edge, the axially inner, radially extending surface bearing axially against the front surface of the first ring, the sealing flange further comprising an undulation that extends from one of the radially outer edge and the radially inner edge of the mounting portion and forms a concave shape with respect to the at least one row of rolling elements, the undulation comprising first and second portions wherein the first portion extends from the one of the radially outer edge and the radially inner edge of the mounting portion in a direction axially away from the first ring and ending at an end point, the second portion extending from the end point in a direction axially towards the first ring such that, with respect to the axial direction, the end point is the portion of the sealing flange that is farthest from the first ring; and a fixing element for fixing the sealing flange to the first ring, wherein the fixing element at least locally covers a region of the front surface of the first ring that is left free by the sealing flange and a part of the sealing flange is adjacent to the region, wherein the fixing element is annular in shape.
