Airtac SGCD Dual Rod Cylinder SGCD125X350
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X350 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 SGCD125X350
Delivering 5734 N of thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod architecture to guarantee identical push and pull output. The four steel tie rods clamp the aluminum barrel securely, while the G1/2 air port supplies the 125 mm piston. Because the rod passes through both covers, it creates a symmetric load path that resists torsional twisting.
This configuration is excellent for about 3440 N of real work, which translates to safely lifting a 292 kg vertical load with a 2:1 margin. The standard TPU seals handle temperatures from -20 to +70 C, though a Viton H option extends this range up to 150 C. Note that this specific SKU lacks a magnet, meaning it cannot host CMSG, DMSG, or EMSG position sensors without upgrading to the -S variant.

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

Where the Airtac SGCD Dual Rod Cylinder SGCD125X350 Is Used
Twin Tool Drive
Simultaneously actuates two opposing forming dies using a single piston, ensuring perfectly synchronized 350 mm strokes without external linkages.
Anti-Rotation Web Guide
Employs the dual rods to prevent rotational drift during the 350 mm travel, maintaining precise alignment for heavy web materials.
Symmetric Transfer Arm
Mounts a sensor cam or tooling on the rear rod end while the front rod pushes a 350 mm transfer carriage along an assembly line.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X350 the Right Cylinder?
Sizing pneumatics requires matching the bore to the required output. If 5734 N both ways is excessive, step down to the 160 mm bore which actually provides more force; conversely, if you need less, the smaller bores are outside the SGCD family. This 125 mm bore hits the low edge of the large-bore ISO 15552 tie-rod range. Choose a double-rod cylinder when your mechanism demands anti-rotation stability, needs to drive twin tooling from opposite ends, or requires a symmetric load path. Available mountings include FA, LB, TC, FTC, TCM1, and TCM2. For this 350 mm stroke, ensure you provide external guide rails to absorb side loads and prevent 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 SGCD125X350 FAQ
Because the double-rod design uses the rod-side area on both faces, force is equal in both directions. It generates 5734 N at 0.5 MPa and 8028 N at 0.7 MPa, with a theoretical maximum of 1169 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, and it features a G1/2 air port.
No, a plain cylinder drifts on air loss and the adjustable 40 mm cushions only decelerate near stroke end; you must add an external rod lock or pilot-operated check valve to hold a load. Additionally, this SKU lacks a magnet and cannot take sensors; you need the -S variant for CMSG, DMSG, or EMSG switches.
