Airtac SGCD Dual Rod Cylinder SGCD125X800
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X800 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 800mm stroke, G1/2 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 SGCD125X800
Delivering 5734 N of equal 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 symmetric load path means push and pull forces match exactly, providing a safe working load of roughly 3440 N for real work, or about 292 kg lifted vertically with a 2:1 margin. Four steel tie rods clamp the aluminum barrel securely to the covers, while the G1/2 port handles the 30-500 mm/s speed range.
Because a rod exits both ends, you can drive two tools simultaneously or mount a sensor cam on the back side. This standard 800 mm stroke SKU lacks a magnet, so it cannot accept CMSG/DMSG/EMSG switches without upgrading to the -S variant. The standard TPU seals handle -20 to +70 C, though a Viton H option extends this to 0-150 C for high-heat environments.

Theoretical Output Force (Ø125mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 5734 N | 5734 N |

Where the Airtac SGCD Dual Rod Cylinder SGCD125X800 Is Used
Dual-End Transfer Pushers
Drives opposing pusher plates on parallel conveyor lanes simultaneously using the equal force from both rod ends.
Balanced Lift Platforms
Lifts heavy jigs vertically with a symmetric load path that prevents piston rod twist and binding over the 800 mm travel.
Twin-Tool Stamping Stations
Powers two forming tools from a single piston, ensuring perfectly synchronized contact pressure on both sides.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X800 the Right Cylinder?
When sizing this double-acting unit, the 125 mm bore sits at the low edge of the SGCD range, offering 5734 N equal force each way at 0.5 MPa. If your application needs less power, there is no smaller SGCD bore, so you would look outside this series; if you need more, step up to the 160 mm bore which yields 9425 N both ways. A double-rod design is the right call when you need anti-rotation guidance, twin tooling driven from one piston, or a symmetric load path. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. At this 800 mm stroke, the long rod requires external guide support to prevent side-load bending and 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 SGCD125X800 FAQ
The double-rod design yields equal force both ways: 5734 N at 0.5 MPa, 8028 N at 0.7 MPa, and a theoretical max of 1169 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a 1.5 MPa proof pressure.
A plain cylinder does not hold load on air loss; the adjustable air cushions only decelerate near stroke ends, so use an external rod lock or pilot-operated check valve for holding. Also, this specific SKU lacks a magnet and cannot take CMSG/DMSG/EMSG sensors without the -S option.
