Airtac SGCD Dual Rod Cylinder SGCD250X300S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X300S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 300mm 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 SGCD250X300S
Delivering 23562 N of thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod piston to provide perfectly symmetric output. The dual-rod architecture creates an identical effective area on each face, guaranteeing equal push and pull force while preventing torsional twist during heavy strokes. Four steel tie rods clamp the aluminum barrel securely to the covers, ensuring structural rigidity under high dynamic loads.
Equipped with a G1 air port and an M42x2.0 rod thread, the unit handles pressures up to 1.0 MPa safely. It yields a safe working load of roughly 14137 N, which translates to lifting about 1201 kg vertically with a 2:1 margin. The included -S piston magnet supports CMSG, DMSG, and EMSG switches for precise end-position detection. Note that on this 250 mm bore, TPU seals are unavailable; standard NBR packing handles -20 to +70 C, while a Viton H option extends heat resistance to 150 C.

Where the Airtac SGCD Dual Rod Cylinder SGCD250X300S Is Used
Twin-Spindle Press
Drives two opposing forming tools simultaneously with equal 23562 N force, ensuring perfectly balanced material deformation without torsional deflection.
Heavy Stamping Die
Applies symmetric downward pressure on large progressive dies, using the dual rods to maintain strict parallelism and prevent binding under high impact loads.
Symmetric Ejector
Ejects heavy machined castings from both sides at once, utilizing the equal bidirectional force to push parts cleanly out of tight fixtures.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X300S the Right Cylinder?
As the largest available bore in this series, the 250 mm sits at the top edge with no larger neighbor, stepping down from the 200 mm option that yields 15079 N both ways at 0.5 MPa. Choose this double-rod configuration when your machine demands anti-rotation guidance, twin tooling driven simultaneously from both ends, or a symmetric load path to prevent rod-side bearing wear. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The built-in -S magnet enables electronic or reed switch sensing. Because the 300 mm stroke is relatively short for this massive bore, side-load stress is minimal, but always guide the external load 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 SGCD250X300S FAQ
Because it is a double-rod cylinder, force is equal in both directions. It outputs 23562 N at 0.5 MPa and 32986 N at 0.7 MPa. The theoretical maximum force is 4805 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa, with a proof pressure of 1.5 MPa.
No, a standard pneumatic cylinder cannot hold a load without live air; the piston will drift and the adjustable 60 mm air cushions only decelerate the stroke near the end caps. For suspended loads, you must install an external rod lock or a pilot-operated check valve.
