Airtac SGCD Dual Rod Cylinder SGCD250X200S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X200S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 200mm 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 SGCD250X200S
Delivering 23562 N of thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a double-rod design to equalize pressure areas. Four steel tie rods clamp the aluminum barrel, and the G1 port feeds the 250 mm bore. Because a rod exits both covers, the piston sees the same effective area on each face, yielding 32986 N at 0.7 MPa with a theoretical ceiling of 4805 kgf at 1.0 MPa. This symmetric layout avoids twist during transit and lets you mount a sensor cam or secondary tool on the back end.
The integrated -S piston magnet supports CMSG, DMSG, and EMSG switches for electronic or reed position detection. Note that TPU seals are not offered on this 250 mm bore; it uses NBR packings, with a Viton H option available for 0 to 150 C environments. Based on the 0.5 MPa rating, you get a safe working load of roughly 14137 N, which translates to lifting about 1201 kg vertically with a 2:1 safety margin.

Theoretical Output Force (Ø250mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 23562 N | 23562 N |
| 0.7 MPa | 32987 N | 32987 N |
| Max (@1.0 MPa) | 5006 kgf | |
Double-rod: the rod passes through both covers, so output force is equal in both directions.

Where the Airtac SGCD Dual Rod Cylinder SGCD250X200S Is Used
Twin-Press Stamping
Drives two forming tools simultaneously from opposite rod ends, ensuring perfectly synchronized high-tonnage pressing without torsional deflection.
Symmetric Indexing Gate
Moves a heavy material handling barrier with equal push and pull thrust, maintaining a balanced load path that prevents guide binding.
Dual-End Divert Arm
Carries a sorting flap on the front rod and a position cam on the rear rod to trigger EMSG sensors, streamlining high-flow package routing.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X200S the Right Cylinder?
As the largest bore in the series, the 250 mm sits at the top edge above the 200 mm option (15079 N at 0.5 MPa). Choose this double-rod configuration when your mechanism demands anti-rotation guidance, symmetric load distribution, or twin tooling driven from one piston. Mounting choices include FA, LB, TC, FTC, TCM1, and TCM2. The -S suffix ensures you have the magnet required for CMSG/DMSG/EMSG sensors. Even at this 200 mm stroke, verify your guide structure to handle potential side loads, as the cylinder itself does not support lateral moments.
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 SGCD250X200S FAQ
It provides equal force both ways: 23562 N at 0.5 MPa, 32986 N at 0.7 MPa, and a maximum theoretical 4805 kgf at 1.0 MPa. It features a 250 mm bore, a 50 mm rod, a G1 port, and 60 mm adjustable air cushions at both ends.
No, the air cushions only decelerate the piston near the end caps and do not act as a brake. To prevent drift on air loss, you must install an external rod lock or a pilot-operated check valve.
