Airtac SGC Standard Cylinder SGC125X275SH
The AirTAC Airtac SGC Standard Cylinder SGC125X275SH is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 275mm 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 SGC125X275SH
Delivering 6136 N of push force at 0.5 MPa, this large-bore tie-rod actuator handles demanding automation tasks. 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. Because it is dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures.
This specific SKU includes a high-temperature Viton (FKM) seal, extending the operating range up to 150 C, and a built-in piston magnet for CMSG, DMSG, or EMSG switches. With a 275 mm stroke and G1/2 port, 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.

Where the Airtac SGC Standard Cylinder SGC125X275SH Is Used
Injection Moulding Extraction
Reaches into hot moulding zones to extract heavy plastic parts, leveraging the Viton seal to withstand ambient radiant heat up to 150 C.
Pallet Diverting
Pushes loaded pallets across a transfer line using 6136 N of thrust, safely operating within a 3682 N practical working load.
Metal Stamping Feed
Advances heavy steel blanks into a press with a 275 mm stroke, relying on the rigid tie-rod construction to resist deflection.
Is the Airtac SGC Standard Cylinder SGC125X275SH the Right Cylinder?
This 125 mm bore provides 6136 N push at 0.5 MPa; if your application requires less force, a smaller bore would be needed outside this series, while stepping up to the 160 mm bore yields 10053 N for heavier demands. The included -S magnet allows seamless integration with CMSG, DMSG, or EMSG position sensors.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered; the adjustable air cushion only decelerates the piston near the end of stroke and does not act as a brake. For suspended loads, install 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 SGC125X275SH FAQ
This 125 mm bore cylinder features a G1/2 air port and generates 6136 N push / 5734 N pull at 0.5 MPa, 8590 N push / 8028 N pull at 0.7 MPa, and a theoretical maximum of 1251 kgf at 1.0 MPa.
No, the double-acting piston will drift if air pressure is lost or the valve is centered. The adjustable air cushions only decelerate the piston at stroke ends and do not function as a locking brake. An external rod lock or pilot-operated check valve is required for position holding.
