Airtac SGCD Dual Rod Cylinder SGCD125X150
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X150 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 150mm 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 SGCD125X150
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 equalize push and pull areas. The G1/2 air port feeds a 32 mm rod passing through both covers, yielding a symmetric load path that prevents rotation. Four steel tie rods clamp the aluminum barrel for high structural rigidity.
Because the pressure area is identical each way, the unit is good for about 3440 N of real work, roughly 292 kg lifted vertically with a 2:1 margin. The 40 mm adjustable air cushions at each end absorb kinetic energy near stroke end. Note this plain SKU lacks a magnet and cannot take a sensor; add the -S option for CMSG/DMSG/EMSG switches.

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

Where the Airtac SGCD Dual Rod Cylinder SGCD125X150 Is Used
Twin-Tool Drive
Operates two opposing forming heads simultaneously from a single piston, keeping cycle times perfectly synchronized.
Anti-Rotation Guide
The dual rods prevent piston twisting during high-friction clamping tasks, ensuring the jaw stays perfectly aligned.
Symmetric Lift
Provides balanced vertical lifting for heavy platens where equal force is required on both the up and down strokes.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X150 the Right Cylinder?
Size this 125 mm bore against its neighbours: the 160 mm gives 9425 N each way at 0.5 MPa, while there is no smaller SGCD option. Choose the double-rod layout when you need anti-rotation guidance, twin tooling driven from both ends, or a back-end sensor cam. Mounting hardware includes FA, LB, TC, FTC, TCM1 and TCM2 brackets. For this 150 mm stroke, guide any side loads externally to prevent rod 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 SGCD125X150 FAQ
It delivers an equal 5734 N both ways at 0.5 MPa and 8028 N at 0.7 MPa, with a theoretical max of 1169 kgf at 1.0 MPa. It uses a G1/2 port, a 32 mm rod, adjustable 40 mm cushions, and operates at 30-500 mm/s.
No, this specific SKU lacks a magnet and cannot accept a switch. You must select the -S variant to use CMSG, DMSG or EMSG sensors for position detection.
