Airtac SGCD Dual Rod Cylinder SGCD250X250
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X250 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 SGCD250X250
Delivering 23562 N of thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder features a piston rod exiting both covers for perfectly symmetric load paths. The G1 air port feeds a bore that safely handles about 14137 N of real work, translating to a vertical lift capacity near 1201 kg with a 2:1 safety margin.
Four steel tie rods clamp the aluminum barrel to the covers, ensuring structural rigidity under high pressure. Because this is a 250 mm bore, TPU seals are not available; instead, it uses NBR packings, with a Viton H option for 0-150 C high-temperature environments. Note that this specific SKU lacks a magnet and cannot accept CMSG, DMSG, or EMSG sensors.

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 SGCD250X250 Is Used
Twin-Spindle Press
Drives two opposing forming tools simultaneously with equal 32986 N force at 0.7 MPa, keeping the press bed perfectly balanced.
Symmetric Lift Platform
Raises and lowers a 1200 kg heavy fixture evenly using both rod ends, preventing torsional twist on the lifting carriage.
Dual-End Transfer
Pushes a heavy pallet from one lane to another while extending a sensor cam out the back to trigger the next stage.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X250 the Right Cylinder?
As the largest bore in the series, the 250 mm sits at the high edge, offering 23562 N at 0.5 MPa, compared to the 200 mm bore which provides 15079 N. Choose this double-rod configuration when your mechanism requires strict anti-rotation guidance, twin tooling driven from both ends, or a symmetric load path to prevent side-loading. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. For any stroke at or above 500 mm, external guide rails are recommended to absorb lateral stress 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 SGCD250X250 FAQ
The push and pull forces are equal at 23562 N at 0.5 MPa and 32986 N at 0.7 MPa. The theoretical maximum is 4805 kgf at 1.0 MPa. It operates from 0.15 to 1.0 MPa with a 1.5 MPa proof pressure.
No, the air cushion only decelerates the piston near stroke end; it will drift on air loss. Use an external rod lock or pilot-operated check valve to hold loads. Also, this non-S SKU lacks a magnet and cannot take CMSG, DMSG, or EMSG sensors.
