Airtac SGCD Dual Rod Cylinder SGCD125X80S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X80S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 80mm 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 SGCD125X80S
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 output force. The G1/2 port feeds a robust four-steel-tie-rod aluminum barrel. Because a rod exits both covers, the pressure area stays identical each way, preventing rod twisting under offset loads.
This SGCD125X80S variant includes a built-in magnet for CMSG, DMSG, or EMSG switches. It handles about 3440 N of real work safely, which translates to lifting roughly 292 kg vertically with a 2:1 margin. Standard TPU seals offer long life across -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 SGCD125X80S Is Used
Twin-Tool Drive Station
Simultaneously pushes two separate workpieces from opposite ends of the piston, keeping cycle times synchronized without adding a second valve.
Balanced Vertical Lift
Lifts roughly 292 kg payloads vertically with a 2:1 safety margin, using the symmetric load path to prevent plunger binding in the vertical plane.
Anti-Rotation Clamp
Secures heavy metal parts during machining by resisting torsional twist through the dual-rod geometry, eliminating the need for external linear bearings.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X80S the Right Cylinder?
When sizing this 125 mm bore, stepping down is not an option as it is the smallest in the SGCD range. Stepping up to the 160 mm bore raises the equal-both-ways force to 9425 N at 0.5 MPa. Choose this double-rod format when your mechanism demands anti-rotation stability, needs to drive two tools simultaneously, or requires a rear-end sensor cam. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. The included -S magnet enables precise position sensing. For this 80 mm stroke, external guide rails are recommended if heavy side loads are present.
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 SGCD125X80S FAQ
The force is equal in both directions due to the double-rod design: 5734 N at 0.5 MPa, 8028 N at 0.7 MPa, and a theoretical maximum of 1169 kgf at 1.0 MPa. It features a G1/2 air port and an M27x2.0 rod-end thread.
No, a standard cylinder cannot hold a load without live air, and the adjustable air cushions only decelerate the piston near stroke end. To prevent drift on a suspended load, you must install an external rod lock or a pilot-operated check valve.
