Airtac SGCD Dual Rod Cylinder SGCD125X350S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X350S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 350mm 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 SGCD125X350S
Delivering 5734 N of thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod piston to balance the load path perfectly. The G1/2 port feeds a 125 mm bore that outputs equal push and pull force, making it ideal for about 3440 N of real work or lifting roughly 292 kg vertically with a safe 2:1 margin.
Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity. Because the -S suffix denotes a built-in piston magnet, you can mount CMSG, DMSG, or EMSG switches for precise end-of-stroke sensing. The standard TPU seals handle -20 to +70 C, while a Viton H option extends heat resistance up to 150 C.

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

Where the Airtac SGCD Dual Rod Cylinder SGCD125X350S Is Used
Twin-Spindle Machining
Drives two opposing machining heads simultaneously using the equal force from both rod ends.
Balanced Lift Station
Lifts roughly 292 kg of vertical payload symmetrically without inducing piston rod twist.
Dual-End Transfer
Pushes a product from one belt to another using the rear rod while the front rod retracts a diverter.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X350S the Right Cylinder?
If your application requires less force, the smaller SGCD160 bore provides 9425 N at 0.5 MPa, whereas this 125 mm bore sits at the low edge of the large-bore SGCD family with 5734 N. A double-rod design is the right call when you need anti-rotation guidance, twin tooling driven from both ends, or a symmetric load path. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 blocks. Since the stroke is 350 mm, which is under the 500 mm side-load threshold, standard guide rules are relaxed, but always keep the load centered. The -S magnet enables electronic position tracking.
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 SGCD125X350S FAQ
The 125 mm bore uses a G1/2 port and generates 5734 N at 0.5 MPa and 8028 N at 0.7 MPa. Because it is a double-rod design, this force is equal in both directions. The theoretical maximum pull force is 1169 kgf at 1.0 MPa.
No, the adjustable air cushions only decelerate the piston near the end caps and do not act as a brake. If you need to hold a load vertically during air loss, you must install an external rod lock or a pilot-operated check valve.
