A Double Rod Cylinder is a pneumatic actuator designed with piston rods on both ends.
This structure makes the cylinder more stable, allows equal force output in both directions, and provides better resistance to side loads.
It is widely used in:
- Automation systems
- Conveyor equipment
- Packaging machinery
- Woodworking machines
- Clamping and positioning devices

✅Why Choose a Double Rod Cylinder?
| Feature | Benefit for Industry |
|---|---|
| Equal force forward & backward | Precision control in automation |
| Strong side-load resistance | Prevent rod bending — longer life |
| High positioning accuracy | Ideal for mechanical guidance |
| Dual mounting options | Easy installation in various layouts |
✅Double Rod Cylinder vs Rodless Cylinder
| Item | Double Rod Cylinder | Rodless Cylinder |
|---|---|---|
| Structure | Two external rods | Internal piston magnetic/linked |
| Side-load capacity | ✅ Very strong | ❌ Weak |
| Max stroke | Medium length | Very long possible |
| Position accuracy | ✅ High | Medium |
| Best for | Clamping, pushing, precise moves | Long-stroke transport |
📌Quick Visual Comparison
Double Rod Cylinder: [ PISTON ]---ROD---|CYL|---ROD---
Rodless Cylinder: [ PISTON ]==MAGNETICS==CARRIAGE---→ long travel
Recommendation:
If you need precision and anti-bending performance → Double Rod Cylinder
If you need long stroke with limited space → Rodless Cylinder
