Abstract

A roller bearing having a first ring, a second ring, at least one row of rolling elements arranged between the rings, and a cage for keeping the rolling elements circumferential in relation to one another. The cage includes first axial retaining means for the first ring and second axial retaining means for the second ring.

First claim

1 . A roller bearing comprising:
a first ring, a second ring, at least one row of rolling elements arranged between the rings, and a cage for holding the rolling elements circumferential in relation to one another, wherein the cage includes first axial retaining means for the first ring and second axial retaining means for the second ring.

2 . The roller bearing according to claim 1 , wherein the cage includes a holding portion for the rolling elements provided with a plurality of cells for the rolling elements and a flange axially extending the holding portion and from which the first and second axial retaining means project.

3 . The roller bearing according to claim 2 , wherein the first and second rings cooperate respectively with the first and second axial retaining means of the cage, the rings being arranged axially at least partially between the related axial retaining means and the holding portion of the cage.

4 . The roller bearing according to claim 1 , wherein the first axial retaining means are offset circumferentially in relation to the second axial retaining means.

5 . The roller bearing according to claim 2 , wherein the first axial retaining means are offset circumferentially in relation to the second axial retaining means and wherein a slot is formed through the holding portion of the cage axially opposite each of the first and second axial retaining means, each of the slots having a circumference at least equal to the circumference of the related hook.

6 . The roller bearing according to claim 1 , wherein each of the first and second axial retaining means includes a radial stop surface axially opposite the related ring.

7 . The roller bearing according to claim 1 , wherein the first and second axial retaining means each have a plurality of hooks spaced apart from one another around the circumference.

8 . The roller bearing according to claim 1 , wherein the first and second axial retaining means are arranged axially on either side of the rolling elements.

9 . The roller bearing according to claim 1 , wherein the flange of the cage radially surrounds the first and second rings.

10 . An assembly for a vehicle, the assembly comprising:
a mirror including a roller bearing having;
a first ring,
a second ring,
at least one row of rolling elements arranged between the rings, and
a cage for holding the rolling elements circumferential in relation to one another, wherein the cage includes first axial retaining means for the first ring and second axial retaining means for the second ring.
