Abstract

The bearing provides a first bearing ring, a second hearing ring and a wear ring attached to the first bearing ring. The wear ring provides at least one hook cooperating with the first bearing ring for the axial retention of the wear ring relative to the first bearing ring. The first hearing ring further provides at least one centering member projecting into and engaging within a complementarily shaped recess of the wear ring, for angular locking of the wear ring relative to the first bearing ring.

First claim

The invention claimed is:

1. A bearing comprising:
a first bearing ring,
a second bearing ring, and
a wear ring fastened to the first bearing ring, wherein
the wear ring is provided with snap fitting means cooperating with the first bearing ring for axial retention of the wear ring relative to the first bearing ring, and wherein
the first bearing ring provides at least one centering member projecting into and engaging within a receiving recess of complementary shape provided in the wear ring, for angular locking of the wear ring relative to the first bearing ring, wherein the wear ring further comprises a body bearing axially against an outer face of the first bearing ring, and an annular centering portion extending axially inwards from the body and provided with a radial contact surface with the first bearing ring.

2. The bearing according to claim 1 , wherein the centering member is integrally formed with the first bearing ring.

3. The bearing according to claim 2 , wherein the centering member is obtained by local deformation of the material of the first bearing ring.

4. The bearing according to claim 1 , wherein the centering member extends from an outer face of the first bearing ring against which the wear ring abuts in axial direction.

5. The bearing according to claim 1 , wherein the receiving recess provided in the wear ring is a blind recess.

6. The bearing of claim 1 , wherein the snap fitting means of the wear ring extends from the centering portion.

7. The bearing according to claim 1 , wherein the first bearing ring further comprises complementary snap fitting means cooperating with the snap fitting means of the wear ring.

8. The bearing according to claim 1 , wherein the snap fitting means of the wear ring further comprises at least one hook.

9. The bearing according to claim 1 , wherein the first bearing ring is an outer ring of the bearing.
