About the Airtac SGC Standard Cylinder SGC125X270S
Delivering 6136 N of push force at 0.5 MPa, this double-acting tie-rod cylinder brings large-bore power to demanding automation. The SGC125X270S utilizes a robust four-steel-tie-rod construction that clamps the aluminum barrel to the covers, ensuring high rigidity under heavy thrust. It is dimensionally interchangeable per the ISO 15552 mounting interface, dropping seamlessly into existing large-bore fixtures. A heterogeneous two-way piston seal retains an oil reservoir for prolonged operational life.
Equipped with a 270 mm stroke and a G1/2 port, the unit operates at speeds of 30-500 mm/s. The trailing -S designates a built-in piston magnet, enabling direct mounting of CMSG, DMSG, or EMSG electronic switches for position sensing. For practical sizing, plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin.

Where the Airtac SGC Standard Cylinder SGC125X270S Is Used
Press Fit Assembly
Drives bearings into heavy housings on an automotive production line, utilizing the 6136 N push force at 0.5 MPa to seat components reliably.
Pallet Stopper Gate
Acts as a robust 270 mm stroke actuator to raise and lower heavy pallet stopping mechanisms in high-throughput distribution centers.
Carton Flap Folder
Folds large corrugated carton flaps on a heavy-duty packaging conveyor, relying on the ISO 15552 mounting interface for rigid fixture integration.
Is the Airtac SGC Standard Cylinder SGC125X270S the Right Cylinder?
When sizing this 125 mm bore option, compare it against its neighbors: the larger 160 mm bore yields 10053 N of push at 0.5 MPa, while there is no smaller SGC bore below 125. This 270 mm stroke exceeds 500 mm? No, but for any extended stroke, always support the load with external guides to prevent rod bending and premature seal wear. Because this SKU includes the -S magnet, you can easily pair it with CMSG or DMSG sensors. Remember that standard air cushions only decelerate the piston near the end of travel; they do not function as a brake. If your application must hold a load vertically during air loss or valve centering, add an external rod lock or a pilot-operated check valve to prevent drift.
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 SGC125X270S FAQ
This 125 mm bore cylinder features a G1/2 port and generates a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push increases to 8590 N and the pull to 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa.
Yes, the -S suffix means this model has a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG switches directly onto the barrel. Structurally, four steel tie rods clamp the assembly together, providing the high rigidity needed to handle large-bore thrust without flexing.
