💡 Why do rc car bearings fail over time.
- Friction builds up inside joints during heavy acceleration runs.
- Dust enters weak seals causing premature wear on the internals.
- Improper alignment creates uneven stress on metal shaft surfaces.
- Using solid couplers prevents slippage better than rubber sleeves.
