Airtac SGCD Dual Rod Cylinder SGCD125X700
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X700 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 700mm 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 SGCD125X700
Delivering 5734 N of thrust in both directions at 0.5 MPa, this large-bore tie-rod cylinder uses a twin-rod piston to provide perfectly symmetric output. The design guarantees equal push and pull forces, making it ideal for about 3440 N of real work or roughly 292 kg lifted vertically with a 2:1 safety margin. A rod extends from each end, which prevents twisting and allows you to drive two separate tools simultaneously.
Built on a genuine ISO 15552 mounting interface, it drops directly into existing large-bore fixtures without compatibility issues. Four steel tie rods clamp the aluminum barrel securely, while the G1/2 port handles the 30-500 mm/s speed range. Because this specific SKU lacks the -S magnet option, it cannot accept CMSG or DMSG sensors. Note that the 40 mm adjustable air cushions only decelerate the piston near the end of the 700 mm stroke; they do not hold the load if air pressure drops.

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

Where the Airtac SGCD Dual Rod Cylinder SGCD125X700 Is Used
Dual-Station Transfer
Uses both extending rods to push pallets on parallel conveyor lanes simultaneously, keeping the stroke perfectly synchronized without external linkages.
Anti-Rotation Indexing
Employs the twin-rod geometry to prevent twist during heavy clamping, ensuring the tool plate stays perfectly aligned through the full 700 mm travel.
Symmetric Lift Carriage
Drives a vertical lifting platform where the equal pull and push forces balance the load, preventing sagging at the end of the 700 mm descent.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X700 the Right Cylinder?
When sizing this unit, compare the 5734 N equal force at 125 mm against the larger 160 mm bore, which outputs 9425 N both ways. The 125 mm bore is the smallest in this heavy-duty series, so if your application requires less than 4000 N, a smaller standard cylinder might fit better. Choose the double-rod configuration when you need strict anti-rotation guidance, symmetric load paths, or a rear rod to act as a sensor cam. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because the 700 mm stroke creates a long lever arm, you must use external guides to prevent rod bending and absorb side loads. Remember that this non-magnetized version cannot support position sensing.
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 SGCD125X700 FAQ
The double-rod design yields equal force both ways: 5734 N at 0.5 MPa and 8028 N at 0.7 MPa. The theoretical maximum is 1169 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, uses a G1/2 port, and features 40 mm adjustable cushions at both ends.
No, this specific SKU does not include a magnet. You must order the -S variant to use CMSG, DMSG, or EMSG sensors. Additionally, the cushions only decelerate the piston; you need an external rod lock or pilot-operated check valve to hold the load vertically.
