Airtac SGCD Dual Rod Cylinder SGCD160X125S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD160X125S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø160mm bore and 125mm stroke, G3/4 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 SGCD160X125S
Delivering 9425 N of thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod architecture to equalize the pressure area on each face. The four steel tie rods clamp the aluminum barrel securely to the covers, while the G3/4 port feeds the 160 mm bore. Because a rod exits both ends, you can drive two tools at once or mount a sensor cam on the back side without losing stroke length.
With the built-in magnet (-S), it accepts CMSG, DMSG, or EMSG switches for precise position feedback. The default TPU seals handle -20 to +70 C, though a Viton H option extends this to 0-150 C. Factoring a 60 percent safety margin, the 9425 N output translates to a safe working load of roughly 5655 N, which is enough to vertically lift about 480 kg with a 2:1 safety factor.

Theoretical Output Force (Ø160mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | 13195 N |
| Max (@1.0 MPa) | 2050 kgf | |
Double-rod: the rod passes through both covers, so output force is equal in both directions.

Where the Airtac SGCD Dual Rod Cylinder SGCD160X125S Is Used
Dual-End Transfer Pusher
Pushes parts from one conveyor lane to another using the front rod, while the rear rod simultaneously retracts a diverter gate.
Symometric Stamping Head
Equal force on the return stroke prevents tool binding in precision stamping fixtures, keeping the load path perfectly centered.
Vertical Lift Gate
Lifts a 480 kg safety gate using the equal both-ways force, ensuring smooth descent and reliable holding via external check valves.
Is the Airtac SGCD Dual Rod Cylinder SGCD160X125S the Right Cylinder?
If your application requires less force, the 125 mm bore provides 5734 N each way; stepping up to the 250 mm bore yields 23562 N. This 160 mm model is the right choice when you need symmetric load distribution, anti-rotation stability, or twin tooling driven from one piston. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The -S suffix ensures compatibility with CMSG, DMSG, and EMSG sensors. Since the 125 mm stroke is well under the 500 mm threshold, side-load guiding requirements are minimal, but external guides are always recommended for precise linear 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 SGCD160X125S FAQ
The double-rod design provides equal force in both directions: 9425 N at 0.5 MPa and 13194 N at 0.7 MPa. The theoretical maximum force is 1922 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa.
No, the air cushions only decelerate the piston near the stroke ends and do not lock the load. If power fails, the load will drift. You must use an external rod lock or a pilot-operated check valve to hold a suspended load safely.
