Abstract

A rolling bearing comprising an outer ring, an inner ring, at least one row of rolling elements disposed radially between the rings, at least one sealing flange mounted in a manner to bear axially against a front surface of one of the rings, and a feature for fixing the sealing flange to the ring. The fixing feature at least locally covers a region of the front surface of the ring that is left free by the sealing flange and a part of the flange that is adjacent to the region. The fixing feature is annular.

First claim

What is claimed is:

1 . A rolling bearing comprising:
an outer ring; an inner ring; at least one row of rolling elements disposed radially between the inner ring and the outer ring; at least one sealing flange mounted in a manner to bear axially against a front surface of one of the outer ring and the inner ring; and a fixing element for fixing the sealing flange to the ring, wherein the fixing element at least locally covers a region of the front surface of the ring that is left free by the sealing flange and a part of the flange that is adjacent to the region, wherein the fixing element is annular in shape.

2 . The rolling bearing according to claim 1 , the sealing flange further comprising a radial mounting portion,
wherein the radial mounting portion is mounted in a manner to bear axially against the front surface of the ring, wherein the radial mounting portion is provided with a free end edge situated radially between the bore and the outer surface of the ring.

3 . The rolling bearing according to claim 2 , wherein the fixing element covers the free end edge of the mounting portion of the sealing flange.

4 . The rolling bearing according to claim 2 , wherein the fixing element covers a part of the internal face of the sealing flange,
wherein the internal face is situated radially on the side away from the free end edge when considering the mounting portion of the flange.

5 . The rolling bearing according to claim 1 , the fixing element further comprising a bead of material.

6 . The rolling bearing according to claim 5 , the fixing element further comprising a bead of adhesive.

7 . The rolling bearing according to claim 5 , the fixing element further comprising a welding bead.

8 . The rolling bearing according to claim 1 , further comprising at least one seal that is fixed to the other ring and engages with the ring,
wherein the sealing flange is axially offset with respect to the seal on the outer side of the bearing.

9 . The rolling bearing according to claim 8 , wherein the sealing flange is mounted axially in contact with the seal.

10 . The rolling bearing according to claim 1 , wherein the sealing flange is mounted axially in direct contact with the front surface of the other ring.
