Airtac SGCD Dual Rod Cylinder SGCD200X250S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD200X250S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø200mm bore and 250mm stroke, G3/4 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 SGCD200X250S
Delivering 15079 N of thrust in both directions at 0.5 MPa, this large-bore double-rod cylinder uses a single piston with a rod exiting both covers to guarantee identical push and pull power. The G3/4 air port feeds the symmetric chamber, yielding a safe working load of roughly 9047 N for real work or a 769 kg vertical lift with a 2:1 margin.
Built on a genuine ISO 15552 tie-rod frame, four steel rods clamp the aluminum barrel to the covers for high structural rigidity. The -S suffix indicates a built-in piston magnet for CMSG/DMSG/EMSG switches, while the standard TPU seals handle -20 to +70 C, with a Viton H option extending heat resistance to 150 C.

Theoretical Output Force (Ø200mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | 21111 N |

Where the Airtac SGCD Dual Rod Cylinder SGCD200X250S Is Used
Twin-Spindle Machining
Drives two opposing machining heads simultaneously from a single symmetric piston, ensuring perfectly synchronized material removal.
Balanced Lift Stations
Lifts heavy platens with equal force both up and down, preventing gravitational sag and maintaining precise vertical positioning.
Dual-End Diverters
Actuates a sorting gate from the back end while the front rod carries a sensor cam, keeping the primary push path clear of obstructions.
Is the Airtac SGCD Dual Rod Cylinder SGCD200X250S the Right Cylinder?
This 200 mm bore sits between the 160 mm option (9425 N both ways) and the 250 mm model (23562 N both ways). Choose a double-rod configuration when your mechanism demands anti-rotation guidance, twin tooling driven from both ends, or a symmetric load path. Mounting hardware includes FA, LB, TC, FTC, TCM1, and TCM2 brackets. The -S magnet enables position sensing. 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 SGCD200X250S FAQ
Because the rod passes through both covers, force is equal both ways: 15079 N at 0.5 MPa and 21110 N at 0.7 MPa. The theoretical maximum is 3075 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa.
No, a standard double-rod cylinder drifts without live air, as the adjustable 50 mm cushions only decelerate the piston near stroke end. To hold a suspended load, install an external rod lock or a pilot-operated check valve.
