| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Improper cleaning before installation | Thoroughly clean both the bearing bore and the shaft to remove any dirt, dust, or manufacturing residue that could cause premature wear. |
| Uneven pressing during mounting | Utilize a bearing press or suitable jig to apply force evenly to the bearing's outer ring when installing onto a shaft, or to the inner ring when installing into a housing, to prevent brinelling or damage. |
