Airtac SGC Standard Cylinder SGC125X1400S
The AirTAC Airtac SGC Standard Cylinder SGC125X1400S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1400mm 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 SGC Standard Cylinder SGC125X1400S
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore actuator is built on a genuine ISO 15552 tie-rod platform. Four steel tie rods clamp the aluminum barrel to the front and rear covers, providing the high rigidity needed to handle large thrust loads without flexing. The two-way piston seal incorporates an oil reservoir for continuous lubrication and extended service life.
With a 1400 mm stroke, plan for about 3682 N of real work at 0.5 MPa, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin. The included -S piston magnet enables CMSG, DMSG and EMSG switches for position sensing, while the standard TPU seals handle temperatures from -20 to +70 C (a Viton H option extends this to 150 C). Air enters via a G1/2 port, and adjustable 40 mm air cushions at both ends decelerate the rod smoothly.

Where the Airtac SGC Standard Cylinder SGC125X1400S Is Used
Pallet Transfer Line
Pushes heavy loaded pallets across a 1.4-meter gap between roller conveyors in automated distribution centers.
Vertical Material Lift
Raises 300 kg tote bins between floor levels in packaging lines, relying on external guides to stabilize the long rod.
Press Ejection System
Ejects finished metal parts from large stamping presses, using the CMSG sensors to confirm full extension.
Is the Airtac SGC Standard Cylinder SGC125X1400S the Right Cylinder?
This 125 mm bore sits at the smaller end of the SGC large-bore family, offering 6136 N push at 0.5 MPa; stepping up to the 160 mm bore increases that to 10053 N if your application demands more power. Because the 1400 mm stroke is highly extended, you must use external guide rails to prevent rod bending and absorb side loads. The ISO 15552 mounting interface means you can reuse existing LB foot, FA flange, or TC trunnion fixtures. Remember that the air cushion only decelerates the piston near the end of travel; it will not hold a suspended load if air pressure drops, so fit an external rod lock or pilot-operated check valve for vertical safety.
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 SGC Standard Cylinder SGC125X1400S FAQ
This 125 mm bore cylinder features a G1/2 air port and a M27x2.0 rod thread. It generates 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push and 8028 N pull at 0.7 MPa, with a theoretical maximum force of 1251 kgf at 1.0 MPa.
No, the standard SGC design does not hold position if air is lost or the valve is centered; the piston will drift. The adjustable air cushion only decelerates the piston near stroke end and does not act as a brake. For vertical holding, you must install an external rod lock or a pilot-operated check valve.
