Airtac SGCD Dual Rod Cylinder SGCD160X125
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD160X125 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 SGCD160X125
Delivering 9425 N of thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod design for perfectly symmetric load paths. The G3/4 port feeds a 40 mm piston rod exiting both covers, yielding an equal 13194 N at 0.7 MPa. This translates to a safe working load of about 5655 N, or roughly 480 kg lifted vertically with a 2:1 safety margin.
Four steel tie rods clamp the aluminium barrel to the covers for high structural rigidity, while adjustable 50 mm air cushions decelerate the piston at both ends. Standard TPU seals handle -20 to +70 C, with a Viton H option extending service to 150 C. Note this specific SKU lacks the -S magnet, so it cannot host CMSG/DMSG/EMSG sensors.

Theoretical Output Force (Ø160mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | 13195 N |

Where the Airtac SGCD Dual Rod Cylinder SGCD160X125 Is Used
Dual-Station Conveyor Divert
Drives two opposing divert arms simultaneously from one piston, ensuring perfectly synchronized package routing across parallel belts.
Anti-Twist Press Head
Keeps a heavy stamping head perfectly aligned during high-force operations by using the symmetric twin-rod structure to prevent rotational drift.
Symmetric Lift Platform
Lifts and lowers a 480 kg vertical load with a 2:1 margin, using the equal push and pull forces to maintain platform stability without external guides.
Is the Airtac SGCD Dual Rod Cylinder SGCD160X125 the Right Cylinder?
Sizing this double-rod unit means balancing against adjacent bores: the 125 mm bore provides 5734 N each way, while the 200 mm bore offers 15079 N at 0.5 MPa. Choose the 160 mm bore when your application demands the 9425 N equal-both-ways output. A twin-rod configuration is the right call when you need anti-rotation guidance, symmetric load distribution, twin tooling driven from one piston, or a back-end sensor cam. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because this is a non-magnetized SKU, position sensing is unavailable. For any stroke exceeding 500 mm, always use external guide rails to prevent side-load damage.
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 SGCD160X125 FAQ
Because the 40 mm rod exits both ends, force is equal in both directions: 9425 N at 0.5 MPa and 13194 N at 0.7 MPa. The theoretical maximum is 1922 kgf at 1.0 MPa. It features a G3/4 port, a 50 mm adjustable cushion at each end, and operates at 30-500 mm/s.
No, a plain double-rod cylinder will drift on air loss, as the air cushions only decelerate the piston near stroke end and do not act as a brake. For suspended or vertical loads, you must install an external rod lock or a pilot-operated check valve.
