Airtac SGC Standard Cylinder SGC125X125STC
The AirTAC Airtac SGC Standard Cylinder SGC125X125STC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 125mm 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 SGC125X125STC
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore actuator is built on a genuine ISO 15552 mounting interface for seamless fixture integration. The four steel tie rods clamp the aluminum barrel to the covers, providing high rigidity under heavy thrust, while the two-way piston seal maintains an internal oil reservoir for long service life.
Equipped with a G1/2 port and a 125 mm stroke, it incorporates a built-in piston magnet for CMSG, DMSG, or EMSG switches. 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. The default TPU seals handle temperatures from -20 to +70 C, with Viton H available for 0-150 C environments.

Where the Airtac SGC Standard Cylinder SGC125X125STC Is Used
Press Ejection
Provides the 6136 N push required to eject heavy stamped metal parts from a hydraulic press bed.
Pallet Diversion
Uses the TC trunnion mount to pivot and divert loaded pallets weighing up to 313 kg on a packaging line.
Gate Actuation
Drives heavy industrial safety gates, utilizing the 125 mm stroke and robust tie-rod build for reliable cycling.
Is the Airtac SGC Standard Cylinder SGC125X125STC the Right Cylinder?
If 6136 N at 0.5 MPa is insufficient, step up to the 160 mm bore offering 10053 N; if your load is lighter, note that 125 mm is the smallest available SGC option. This TC trunnion configuration suits pivoting loads, but remember a plain cylinder drifts if air is lost or the valve is centered, so add an external rod lock or pilot-operated check valve for secure holding. At 125 mm stroke, side-load risks are minimal, but always guide the rod to prevent bending.
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 SGC125X125STC FAQ
This 125 mm bore cylinder features a G1/2 port and delivers 6136 N push / 5734 N pull at 0.5 MPa, 8590 N push / 8028 N pull at 0.7 MPa, with a theoretical maximum of 1251 kgf at 1.0 MPa.
Yes, the -S designation means it has a built-in magnet for CMSG, DMSG, or EMSG switches. It is dimensionally interchangeable per the ISO 15552 mounting interface, allowing the TC trunnion and other standard accessories to drop right in.
