Airtac SGCD Dual Rod Cylinder SGCD250X160S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X160S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 160mm stroke, G1 air ports and adjustable end cushioning. Its large-bore tie-rod build delivers high thrust and drops into standardized ISO 15552 mounting on heavy automation.

About the Airtac SGCD Dual Rod Cylinder SGCD250X160S
Delivering 23562 N of thrust in both directions at 0.5 MPa, this large-bore double-rod cylinder uses a single Ø50 mm piston rod passing through both covers to equalize pressure areas. The four steel tie rods clamp the aluminum barrel securely, providing high structural rigidity for heavy-duty automation. Because the piston sees the same rod-side area on each face, push and pull forces remain identical at 32986 N when supplied at 0.7 MPa. It features a G1 air port and adjustable 60 mm cushions at both ends. A built-in piston magnet is included for position sensing.
Dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore pneumatic fixtures without custom brackets. The -S suffix enables use with CMSG, DMSG, and EMSG switches for precise end-of-stroke detection. Note that TPU seals are unavailable on this 250 mm bore; standard NBR packings handle temperatures from -20 to +70 C, while a Viton H option extends this to 150 C. With a 0.5 MPa input, the safe working load is roughly 14137 N, capable of vertically lifting about 1201 kg with a 2:1 safety margin.

Theoretical Output Force (Ø250mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 23562 N | 23562 N |

Where the Airtac SGCD Dual Rod Cylinder SGCD250X160S Is Used
Twin-Press Stamping
Drives two synchronized forming tools from opposite rod ends, ensuring perfectly balanced force distribution across large metal panels.
Symmetric Lift Platform
Lifts heavy industrial pallets using equal force on the raise and lower strokes, preventing gravitational drift during descent.
Anti-Rotation Diverter
Uses the dual-rod structure to push heavy packages across a belt without the torsional twisting common to single-rod actuators.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X160S the Right Cylinder?
As the largest bore in the SGCD family, this 250 mm model sits at the high edge of the range, offering maximum equal-both-ways thrust. If your application requires less force, stepping down to the 200 mm bore drops the 0.5 MPa output to 15079 N, while the 160 mm bore provides 9425 N. Choose this double-rod configuration when your machine demands anti-rotation guidance, symmetric load paths, or needs to drive twin tooling simultaneously from one piston. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. The included -S magnet supports CMSG, DMSG, and EMSG sensors. For this 160 mm stroke, external guide rails are recommended to absorb any lateral side loads and prevent binding.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Long-stroke side load — support the rod end
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load; support long strokes at the rod end.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SGCD Dual Rod Cylinder SGCD250X160S FAQ
Because it is a double-rod cylinder, force is equal both ways using the pull-side area. It generates 23562 N at 0.5 MPa and 32986 N at 0.7 MPa in both directions. The theoretical maximum is 4805 kgf at 1.0 MPa. The air port size is G1.
No, a standard pneumatic cylinder drifts when air is lost or the valve is centered. The adjustable 60 mm cushions only decelerate the piston near the stroke ends; they do not act as a brake. For suspended or vertical loads, you must install an external rod lock or a pilot-operated check valve.
