| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Forcing the bearing onto the shaft with excessive hammer force, potentially damaging raceways or the retainer. | Use a proper bearing press or a soft-faced hammer with controlled blows, applying force to the inner ring only. |
| Contaminating the bearing during installation due to dirty hands, tools, or environment. | Maintain a clean work area and handle the bearing with clean gloves or tools to prevent ingress of dirt or debris. |
