Airtac SGC Standard Cylinder SGC125X140S
The AirTAC Airtac SGC Standard Cylinder SGC125X140S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 140mm 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 SGC125X140S
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is built for large-bore pneumatic tasks. 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 to ensure long service life. Plan for about 3682 N of actual work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin.
The built-in -S piston magnet allows direct mounting of CMSG, DMSG, or EMSG switches for position sensing. It features a 32 mm rod, a G1/2 air port, and adjustable 40 mm air cushions at both ends to decelerate the piston smoothly. You can also specify Viton H seals for 0-150 C high-temperature environments.

Where the Airtac SGC Standard Cylinder SGC125X140S Is Used
Press Fit Tooling
Drives small bushings and bearings into automotive transmission housings using its 6136 N thrust capability.
Pallet Stopper Gate
Acts as a heavy-duty pneumatic stop gate on converging roller conveyors handling loaded pallets.
Flap Folding Arm
Executes positive mechanical folding of heavy cardboard flaps on large industrial carton sealing lines.
Is the Airtac SGC Standard Cylinder SGC125X140S the Right Cylinder?
This 125 mm bore sits at the entry point of the SGC large-frame family, so if your application requires less thrust you must step down to a smaller non-SGC series. If you need more power, the next size up is the 160 mm bore, which provides 10053 N of push at 0.5 MPa. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG electronic and reed sensors.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the end cushions only slow the piston near stroke limits and act as no brake. To suspend a load safely during an outage, add an external rod lock or a pilot-operated check valve to your assembly.
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 SGC125X140S FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it provides 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa, and the air port size is G1/2.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so it drops directly into existing large-bore ISO 15552 fixtures and foot brackets without modification.
