Airtac SGCD Dual Rod Cylinder SGCD250X700
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X700 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 700mm 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 SGCD250X700
Delivering 23562 N of equal output force in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod piston to balance loads and prevent rotation. The double-rod layout drives two tools simultaneously or mounts a rear sensor cam, while four steel tie rods clamp the aluminum barrel for high structural rigidity. It features a G1 air port, a 60 mm adjustable air cushion at each end, and a 700 mm stroke.
Because the rod passes through both covers, the pull-side area dictates the force, yielding 32986 N at 0.7 MPa and a theoretical maximum of 4805 kgf at 1.0 MPa. This symmetric load path is good for about 14137 N of real work, roughly 1201 kg lifted vertically. Note that TPU seals are unavailable for this 250 mm bore, which uses NBR standard seals, though a Viton H option extends operation to 150 C. This non-magnet SKU cannot take a sensor; the -S variant is required for CMSG/DMSG/EMSG switches.

Theoretical Output Force (Ø250mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 23562 N | 23562 N |

Where the Airtac SGCD Dual Rod Cylinder SGCD250X700 Is Used
Twin-Press Stamping
Drives two synchronized forming tools from opposite rod ends to stamp heavy-gauge metal panels without rotational twist.
Symmetric Platen Lowering
Lowers a heavy machinery platen with a perfectly balanced load path, preventing uneven wear on the guiding columns during descent.
Dual-End Diverting
Actuates opposing diverter arms simultaneously on a high-speed packaging line using a single rear-mounted cam for timing.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X700 the Right Cylinder?
As the largest bore in the range, the 250 mm sits at the high edge, offering 23562 N each way at 0.5 MPa, stepping up from the 200 mm bore that provides 15079 N. Choose a double-rod configuration when you need strict anti-rotation guidance, twin tooling on one axis, or a symmetric load path to prevent rod-side sag. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. For this 700 mm stroke, you must use external guides to prevent rod bending and absorb side loads. Remember that a plain cylinder drifts on air loss; add an external rod lock or pilot-operated check valve to hold a suspended load, as the cushions only decelerate.
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 SGCD250X700 FAQ
It delivers equal force both ways: 23562 N at 0.5 MPa, 32986 N at 0.7 MPa, and a theoretical max of 4805 kgf at 1.0 MPa. It features a 250 mm bore, 700 mm stroke, G1 port, M42x2.0 rod thread, and 60 mm adjustable cushions.
The twin-rod design provides anti-rotation guidance and a symmetric load path for stable twin-tool driving. It cannot hold a load on air loss; the cushions only decelerate, so you need an external rod lock or pilot-operated check valve for load holding.
