Airtac SGCD Dual Rod Cylinder SGCD250X25
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X25 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 25mm 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 SGCD250X25
Delivering 23562 N of equal force in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod piston to balance loads and prevent rotation. A rod exits each cover, creating a symmetric load path that drives two tools simultaneously. It handles a safe working load of about 14137 N, which translates to lifting roughly 1201 kg vertically with a 2:1 margin.
Four steel tie rods clamp the aluminum barrel for high structural rigidity, and the G1 air port feeds the chamber efficiently. Because this is a 250 mm bore, TPU seals are not available; instead it uses NBR packings, with a Viton H option for 0 to 150 C heat. Note that this specific SKU lacks a magnet and cannot mount position sensors, whereas an -S variant accepts CMSG, DMSG, or EMSG switches.

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 SGCD250X25 Is Used
Twin-Press Tooling
Drives two forming dies simultaneously from opposite rod ends, ensuring perfectly synchronized stamping without torsional deflection.
Balanced Lift Platform
Lifts heavy 1200 kg machinery assemblies vertically using the symmetric load path to prevent platform twisting during elevation.
Dual-End Diverters
Actuates sorting flappers on both sides of a high-speed belt with one piston, keeping package routing perfectly aligned.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X25 the Right Cylinder?
Sizing this 250 mm bore against its neighbors shows the scale: stepping down to a 200 mm bore yields 15079 N each way at 0.5 MPa, while the 250 mm sits at the top edge with 23562 N. Choose the double-rod layout when your mechanism demands anti-rotation guidance, twin tooling stations, or a symmetric load path. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Since this SKU has no -S suffix, it cannot accept magnetic sensors; add the -S option for CMSG, DMSG, or EMSG switches. Even with a short 25 mm stroke, always support side loads with external guide rails to 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 SGCD250X25 FAQ
The double-rod design yields equal force both ways: 23562 N at 0.5 MPa and 32986 N at 0.7 MPa. The theoretical maximum is 4805 kgf at 1.0 MPa. Operating pressure spans 0.15 to 1.0 MPa, with a 1.5 MPa proof rating.
No, a standard cylinder drifts without live air, as the adjustable 60 mm cushions only decelerate the piston near stroke end. To hold a load securely, install an external rod lock or a pilot-operated check valve.
