Airtac SGCD Dual Rod Cylinder SGCD250X80S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X80S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 80mm 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 SGCD250X80S
Delivering 23562 N of equal thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod piston to balance your load path perfectly. A rod exits each cover, meaning the effective area is identical on extension and retraction. The four steel tie rods clamp the aluminum barrel securely, and the bore features a G1 air port with an M42x2.0 rod thread.
Because the piston carries a magnet, this -S SKU supports CMSG, DMSG, and EMSG switches for position sensing. 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 degree Celsius environments. The 60 mm adjustable air cushions at both ends absorb heavy kinetic energy, yielding a safe working load of roughly 14137 N or a 1201 kg vertical lift with a 2:1 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 SGCD250X80S Is Used
Twin-Press Stamping
Drives two synchronized forming tools from one piston, using the equal both-ways thrust to hit left and right dies simultaneously.
Balanced Lift Platform
Lifts heavy pallets or chassis frames evenly. The symmetric load path prevents binding and keeps the platform perfectly level.
Dual-End Transfer
Pushes a part forward on extension while retracting a completed component from the secondary line using the rear rod.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X80S the Right Cylinder?
As the largest bore in the range, the 250 mm sits at the high edge above the 200 mm option (which provides 15079 N both ways at 0.5 MPa). Choose this double-rod design when you need strict anti-rotation resistance, symmetric load distribution, or a rear rod to drive a secondary tool or sensor cam. It supports FA, LB, TC, FTC, TCM1, and TCM2 mounts per the ISO 15552 mounting interface. Even at 80 mm stroke, verify your external guide rails to prevent side-load damage, and remember a plain cylinder drifts on air loss—use an external rod lock for holding.
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 SGCD250X80S FAQ
The force is equal in both directions because of the double-rod design. It generates 23562 N at 0.5 MPa and 32986 N at 0.7 MPa. The theoretical maximum is 4805 kgf at 1.0 MPa. It features a G1 port and a 60 mm cushion stroke.
No, the air cushions only decelerate the piston near the stroke ends and do not act as a brake. If power fails, the load will drift. You must install an external rod lock or a pilot-operated check valve to hold a suspended load safely.
