Airtac SGC Standard Cylinder SGC125X230SFA
The AirTAC Airtac SGC Standard Cylinder SGC125X230SFA is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 230mm 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 SGC125X230SFA
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is built for heavy-duty automation. Four steel tie rods clamp the aluminium barrel to the covers, ensuring high rigidity while the two-way piston seal maintains an internal oil reservoir for long service life. The G1/2 port and M27x2.0 rod thread handle the demanding airflow of the 125 mm bore.
Because the -S magnet is present, you can directly mount CMSG, DMSG, or EMSG sensors for position detection. For practical sizing, 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 standard TPU seals operate from -20 to +70 C, with a Viton H option available for environments up to 150 C.

Where the Airtac SGC Standard Cylinder SGC125X230SFA Is Used
Press Die Ejection
Provides the robust 6136 N push stroke needed to eject heavy formed metal panels from hydraulic press beds.
Pallet Stopper Gate
Acts as a high-force pneumatic stop gate on heavy-duty roller conveyors, securely halting loaded pallets.
Injection Mold Clamping
Utilizes its 230 mm stroke and rigid tie-rod build to position and hold large injection molding tooling halves.
Is the Airtac SGC Standard Cylinder SGC125X230SFA the Right Cylinder?
When sizing this 125 mm bore unit, verify if the 6136 N push force at 0.5 MPa provides adequate thrust, as stepping up to the 160 mm bore yields 10053 N. If your application requires less force, there is no smaller SGC bore, so you would need to look outside the series. The included FA flange accessory bolts directly to the ISO 15552 mounting interface, and the 230 mm stroke is well within standard limits. Since this is a double-acting cylinder, remember that exhausting air or centering the valve will cause the piston to drift; the end cushions only decelerate the stroke and do not act as a brake. For suspended loads, add an external rod lock or pilot-operated check valve.
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 SGC125X230SFA 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 force of 1251 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so standard FA flanges and other accessories fit perfectly. The -S magnet in this model allows direct fitting of CMSG, DMSG, or EMSG electronic switches.
