Airtac SGC Standard Cylinder SGC250X1100S
The AirTAC Airtac SGC Standard Cylinder SGC250X1100S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 1100mm stroke, G1 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 SGC250X1100S
Delivering 24543 N of push force at 0.5 MPa, this double-acting large-bore ISO 15552 tie-rod cylinder handles heavy-duty automation. Four steel tie rods clamp the aluminum barrel to the front and rear covers, providing high rigidity under extreme thrust, while the two-way piston seal maintains an internal oil reservoir for long service life. Plan for about 14726 N of real work at 0.5 MPa, which translates to lifting roughly 1251 kg vertically with a 2:1 safety margin.
Because this SKU includes the -S magnet, it directly supports CMSG, DMSG, and EMSG position switches. The Ø250 bore uses a G1 air port, an M42x2.0 rod thread, and a 60 mm adjustable air cushion at both ends. Note that TPU seals are not offered for this bore size; the front-cover packing and buffer gasket are NBR, with a Viton H high-temperature option available for 0-150 C environments.

Where the Airtac SGC Standard Cylinder SGC250X1100S Is Used
Heavy Press Ejection
Pushes finished stampings out of a 2000-ton mechanical press using 24543 N at 0.5 MPa, absorbing end-of-stroke impact via the 60 mm adjustable air cushion.
Palletizer Lift Head
Raises 1200 kg unit loads across a 1100 mm vertical span, relying on the -S magnet and DMSG switches to confirm elevation at the packaging line.
Foundry Mold Transfer
Shifts heavy resin-bonded sand molds along an assembly track, with the NBR buffer gaskets withstanding ambient foundry heat up to 70 C.
Is the Airtac SGC Standard Cylinder SGC250X1100S the Right Cylinder?
This 250 mm bore sits at the top of the SGC range, so if 24543 N at 0.5 MPa is excessive, step down to the 200 mm bore (15708 N push). There is no larger standard SGC bore. The 1100 mm stroke demands careful external guidance to prevent rod bending and side-load damage during long extensions. Additionally, a plain cylinder drifts when air is lost or the valve is centered; the air cushions only decelerate the piston near stroke end and do not act as a brake. To hold a suspended load safely, install an external rod lock or a 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 SGC250X1100S FAQ
The Ø250 bore features a G1 air port, an M42x2.0 rod thread, and a 50 mm piston rod. It generates 24543 N push and 23562 N pull at 0.5 MPa, 34360 N push and 32986 N pull at 0.7 MPa, with a theoretical maximum of 5006 kgf at 1.0 MPa. The operating speed range is 30-500 mm/s.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so it drops directly into standard large-bore ISO 15552 fixtures and accessories. The included -S piston magnet enables CMSG, DMSG, and EMSG electronic or reed switches for end-of-stroke detection.
