| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Applying excessive force during installation, leading to brinelling or deformation of the polycarbonate raceways. | Utilize a controlled press or bearing installation tool to apply force only to the inner ring during shaft mounting. |
| Using incompatible lubricants that can degrade the polycarbonate material over time. | Consult the bearing manufacturer's compatibility chart for lubricants suitable for polycarbonate bearings. |
