Airtac SGC Standard Cylinder SGC125X100S
The AirTAC Airtac SGC Standard Cylinder SGC125X100S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 100mm 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 SGC125X100S
Generating 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles substantial workloads. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, while the two-way piston seal maintains an internal oil reservoir for long-term lubrication. Plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin.
The integrated -S piston magnet directly supports CMSG, DMSG, and EMSG switches for end-of-stroke detection. Fluid power connects via a G1/2 port, and the M27x2.0 rod end threads into your mechanical linkage. Because it adheres to the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures without custom bracket fabrication.

Where the Airtac SGC Standard Cylinder SGC125X100S Is Used
Press Fit Assembly
Drives bearings into heavy housings on an automated press line, utilizing the 6136 N push force to seat components reliably.
Pallet Stopper Gate
Acts as a heavy-duty stop gate in conveyor transfer zones, securely halting loaded pallets up to 313 kg using the magnetic piston for timing.
Carton Flap Folder
Folds large corrugated carton flaps in high-speed packaging machinery, where the 100 mm stroke and CMSG sensors ensure precise folding cycles.
Is the Airtac SGC Standard Cylinder SGC125X100S the Right Cylinder?
This 125 mm bore sits at the entry point of the SGC large-frame family, offering 6136 N push at 0.5 MPa. If your application demands less energy, you must step outside the SGC range, as there is no smaller bore in this series; conversely, scaling up to the 160 mm bore provides 10053 N for heavier cycle requirements. The 100 mm stroke is well within standard limits, keeping rod-bending stress minimal without auxiliary guides.
Remember that the adjustable 40 mm air cushion only decelerates the piston near the end caps and does not function as a braking lock. If your process drops air pressure or centers the valve, the load will drift; specify an external rod lock or pilot-operated check valve for suspended or vertical loads.
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 SGC125X100S FAQ
The SGC125X100S delivers 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 of 1251 kgf at 1.0 MPa. The air port size is G1/2.
Yes, the -S suffix indicates a built-in magnet compatible with CMSG, DMSG, and EMSG switches. It is dimensionally interchangeable per the ISO 15552 mounting interface, allowing it to use the same standard fixtures and accessories as other ISO 15552 cylinders.
