| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Applying excessive force during installation, potentially damaging the polycarbonate race. | Use a bearing press or appropriate tool for a controlled, even press-fit. Avoid hammering. |
| Using incompatible lubricants that can degrade polycarbonate. | Consult the lubricant compatibility chart for polycarbonate bearings or use food-grade, inert lubricants. |
