Airtac SGCD Dual Rod Cylinder SGCD250X350S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X350S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 350mm 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 SGCD250X350S
Delivering 23562 N of equal force in both directions at 0.5 MPa, this large-bore double-rod cylinder excels in heavy-duty symmetric motion. A rod exits both covers on a shared piston, ensuring the push and pull areas are identical. It features a G1 air port and a robust M42x2.0 rod thread. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity.
Because the pressure area is identical each way, the output force stays perfectly balanced. This makes it good for about 14137 N of real work, roughly 1201 kg lifted vertically with a 2:1 safety margin. The -S suffix denotes a built-in piston magnet for CMSG, DMSG, or EMSG switches. Note that TPU seals are unavailable on this 250 mm bore; it uses NBR standard seals, though a Viton H option extends operating temps to 150 C.

Where the Airtac SGCD Dual Rod Cylinder SGCD250X350S Is Used
Twin-Press Stamping
Drives two symmetrical forming tools simultaneously from opposite rod ends, keeping heavy stamping forces perfectly balanced without torsional deflection.
Symmetric Lift Platform
Provides non-rotating vertical guidance for heavy lifting platens, using the equal both-ways force to raise and lower substantial loads with stability.
Dual-Side Divert Gate
Actuates a routing gate from the rear rod end while the front end carries a sensor cam, allowing compact track integration and precise package diversion.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X350S the Right Cylinder?
As the largest bore in the range, the 250 mm sits at the high edge of the SGCD scale, delivering 23562 N both ways at 0.5 MPa. If your application requires less force, stepping down to the 200 mm bore yields 15079 N each way. Choose this double-rod configuration when you need strict anti-rotation guidance, twin tooling driven from one piston, or a symmetric load path. It supports FA, LB, TC, FTC, TCM1, and TCM2 mountings. The included -S magnet enables CMSG/DMSG/EMSG position sensing. For this 350 mm stroke, ensure external guide rails carry any lateral side-load to prevent premature seal wear.
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 SGCD250X350S 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 each way. The theoretical maximum is 4805 kgf at 1.0 MPa. It uses a G1 port.
No, a plain cylinder drifts without live air, as the adjustable 60 mm cushions only decelerate near stroke end. For a held load, install an external rod lock or pilot-operated check valve. The -S magnet works with CMSG/DMSG/EMSG sensors.
