## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are best for conveyor belts in heavy-duty applications?
**A**: For heavy-duty applications, steel-reinforced rubber belts offer optimal durability and load capacity, while polymer belts provide excellent chemical resistance for specific environments.

### Q: How often should conveyor rollers be maintained?
**A**: Conveyor rollers typically require lubrication every 3-6 months and bearing inspection quarterly, but frequency depends on operating hours, load, and environmental conditions.

### Q: What factors determine conveyor belt lifespan?
**A**: Belt lifespan depends on material quality, tension, load weight, operating speed, environmental exposure, and proper maintenance of the carcass and support components.
