A clutch-release bearing device includes a bearing having a non-rotating ring, a rotating ring with a rolling portion for supporting rolling elements, a contact portion extending from the rolling portion and radially away from the non-rotating ring, and a guide portion extending toward the non-rotating ring and disposed axially against the contact portion to form a fold, and at least one row of rolling elements disposed between the non-rotating and rotating rings. A wear ring is movably mounted on the guide portion of the rotating ring and is configured to contact the clutch mechanism diaphragm. The ring includes a polymeric body and a stiffening insert configured to stiffen the body, the body having a retaining portion disposed generally axially between the rotating ring rolling and contact portions and configured to axially retain the wear ring in relation to the rotating ring.
