- **Caution**: 
- **Caution**: 

### Q: What materials are commonly used in pneumatic cylinder construction?
**A**: Pneumatic cylinders are typically constructed from aluminum alloy for lightweight applications, stainless steel for corrosion resistance, or carbon steel for high-strength industrial use.

### Q: What are the main components in a pneumatic cylinder bill of materials?
**A**: Key BOM components include the cylinder barrel, piston, piston rod, end caps, and various seals that ensure proper compression and prevent air leakage.

### Q: How does a pneumatic cylinder convert energy into mechanical motion?
**A**: Pneumatic cylinders use compressed air energy to move a piston within a barrel, creating linear mechanical force and motion through controlled air pressure differentials.
