Airtac SGCD Dual Rod Cylinder SGCD125X600
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X600 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 600mm 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 SGCD125X600
Delivering 5734 N of thrust in both directions at 0.5 MPa, this double-acting tie-rod cylinder uses a piston rod exiting both covers to equalize the pressure area. That symmetric load path prevents rod twisting and lets you mount twin tooling or a rear sensor cam. Good for about 3440 N of real work, it safely lifts roughly 292 kg vertically. The four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity.
This large-bore 125 mm unit features a G1/2 port, a 32 mm rod with an M27x2.0 thread, and 40 mm adjustable air cushions at both ends. It conforms strictly to the ISO 15552 mounting interface, dropping directly into standard large-bore fixtures. The default TPU seals handle -20 to +70 C, while a Viton H option extends heat resistance up to 150 C. Note this specific SKU lacks the -S magnet, so it cannot accept CMSG or DMSG switches.

Theoretical Output Force (Ø125mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 5734 N | 5734 N |
| 0.7 MPa | 8027 N | 8027 N |

Where the Airtac SGCD Dual Rod Cylinder SGCD125X600 Is Used
Twin-Tool Indexing
Drives two opposing forming tools simultaneously from a single actuator, using the equal both-ways thrust to maintain perfectly synchronized machining pressure.
Balanced Vertical Lift
Lifts and lowers heavy platens symmetrically, leveraging the 5734 N equal force to prevent the load from shifting or twisting during transit.
Dual-End Transfer
Pushes a product from one conveyor lane to another using the rear rod extension, saving space by avoiding a secondary return actuator.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X600 the Right Cylinder?
This 125 mm bore sits at the low edge of the SGCD range, stepping up to the 160 mm bore which outputs 9425 N both ways at 0.5 MPa. Choose the double-rod format when your mechanism demands anti-rotation guidance, a symmetric load path, or dual-tool drive from one actuator. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because the 600 mm stroke is quite long, always provide external guide support to prevent rod bending under side loads. If you need position sensing, select an -S variant instead, as this base model cannot carry magnetic switches.
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 SGCD125X600 FAQ
Because the rod passes through both covers, force is equal in both directions. It generates 5734 N at 0.5 MPa and 8028 N at 0.7 MPa. The theoretical maximum is 1169 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, and the air port is G1/2.
No, a plain cylinder drifts without live air, as the 40 mm cushions only decelerate near stroke end and act as neither a lock nor a brake. For vertical load holding, you must install an external rod lock or a pilot-operated check valve.
