Airtac SGCD Dual Rod Cylinder SGCD125X80
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X80 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 80mm 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 SGCD125X80
Delivering 5734 N of thrust each way at 0.5 MPa, the AirTAC SGCD125X80 is a genuine ISO 15552 tie-rod cylinder with a rod exiting both covers. This double-acting design uses the rod-side piston area on both faces, ensuring push and pull forces remain identical. A practical safe working load is about 3440 N, capable of vertically lifting roughly 292 kg with a 2:1 safety margin.
Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity. The G1/2 port supplies air to the 125 mm bore, while adjustable 40 mm cushions decelerate the piston at both ends. Note this specific SKU lacks a magnet and cannot accept CMSG or DMSG sensors.

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

Where the Airtac SGCD Dual Rod Cylinder SGCD125X80 Is Used
Twin-Tool Transfer
Drives two opposing grippers simultaneously from a single piston, keeping pick-and-place timing perfectly synchronized.
Balanced Vertical Lift
Lifts roughly 292 kg loads symmetrically without rod bias, preventing uneven seal wear during heavy elevation tasks.
Anti-Twist Clamping
Holds workpieces flat against a fixture using dual-end pressure, eliminating rotational drift during heavy machining.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X80 the Right Cylinder?
Size this 125 mm bore against its neighbors: the larger 160 mm bore yields 9425 N each way at 0.5 MPa, while the 250 mm bore tops the range at 23562 N. Choose the SGCD double-rod format when your mechanism requires anti-rotation guidance, symmetric load distribution, twin tooling driven from one piston, or a rear rod acting as a sensor cam. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this 80 mm stroke is short, side-load risks are minimal, but any future build exceeding 500 mm should incorporate external guide rails 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 SGCD125X80 FAQ
Because it is a double-rod cylinder, force is equal in both directions: 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 and uses a G1/2 air port.
No to both. The air cushions only decelerate the piston near stroke end; they do not lock, so you need an external rod lock or pilot-operated check valve to hold a load. Also, this specific SKU has no magnet and cannot mount CMSG/DMSG sensors.
