Airtac SGCD Dual Rod Cylinder SGCD250X250S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X250S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 250mm 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 SGCD250X250S
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 the pressure area. Four steel tie rods clamp the aluminum barrel to the covers, providing structural rigidity for heavy industrial tasks. The G1 air port feeds the chamber, while the built-in -S magnet enables position sensing with CMSG, DMSG, or EMSG switches.
Because the rod exits both ends, the load path is completely symmetric, preventing torsional twist and allowing you to mount tooling or a sensor cam at the back. This configuration yields a safe working load of roughly 14137 N, which translates to lifting about 1201 kg vertically with a 2:1 safety margin. Note that the Ø250 bore uses NBR seals rather than TPU, with a Viton H option available for 0 to 150 degree Celsius environments.

Theoretical Output Force (Ø250mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 23562 N | 23562 N |
| 0.7 MPa | 32987 N | 32987 N |

Where the Airtac SGCD Dual Rod Cylinder SGCD250X250S Is Used
Twin-Spindle Machining
Drives two opposing machining heads simultaneously with equal 23562 N force, keeping the cutting cycle balanced and synchronized.
Symmetric Press Lift
Lifts heavy press platens without lateral drift, using the through-rod design to maintain perfectly parallel vertical alignment.
Dual Transfer Divert
Pushes product across a conveyor from either end, utilizing the back rod to actuate a secondary diverting mechanism.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X250S the Right Cylinder?
As the largest bore in the series, this 250 mm model sits at the top edge of the range, offering 23562 N at 0.5 MPa compared to 15079 N on the 200 mm version. If your application requires less force, step down to the 160 mm bore which provides 9425 N. Choose a double-rod configuration when you need strict anti-rotation guidance, symmetric load distribution, or dual tooling on a single axis. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The included -S magnet supports electronic or reed sensors. For this 250 mm stroke, ensure external guide rails are used to absorb 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 SGCD250X250S FAQ
The G1 port feeds a bore that outputs 23562 N at 0.5 MPa and 32986 N at 0.7 MPa. Because it is a double-rod design, this force is identical in both directions. The theoretical maximum at 1.0 MPa is 4805 kgf.
No, the adjustable 60 mm air cushions only decelerate the piston near the end of stroke; they do not lock the load. If you need to maintain position during air loss, install an external rod lock or a pilot-operated check valve.
