Airtac SGC Standard Cylinder SGC250X950
The AirTAC Airtac SGC Standard Cylinder SGC250X950 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 950mm 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 SGC250X950
Delivering 24543 N of push force at 0.5 MPa, this double-acting tie-rod cylinder handles the most demanding large-bore pneumatic tasks. Its four steel tie rods clamp the aluminium barrel to the covers for extreme rigidity, while the standardized ISO 15552 mounting interface ensures it drops directly into existing heavy-duty fixtures.
For practical sizing, plan for about 14726 N of real work at 0.5 MPa, which equates to lifting roughly 1251 kg vertically with a 2:1 safety margin. This 250 mm bore uses a G1 air port and M42x2.0 rod thread. Note that TPU seals are not offered here; the front-cover packing is NBR, with a Viton H option available for 0-150 C high-temperature environments. Since this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches.

Where the Airtac SGC Standard Cylinder SGC250X950 Is Used
Heavy Stamp Presses
Generates the massive 24543 N push at 0.5 MPa needed to actuate large metal stamping dies.
Pallet Lift Stations
Lifts loaded pallets weighing up to 1251 kg vertically using the 950 mm stroke with a 2:1 margin.
Concrete Moulding
Vibrates and compacts large concrete moulds where the NBR seals withstand harsh industrial grit.
Is the Airtac SGC Standard Cylinder SGC250X950 the Right Cylinder?
As the largest bore in the SGC family, there is no larger standard option; if 24543 N at 0.5 MPa is excessive, step down to the 200 mm bore which provides 15708 N. Because the 950 mm stroke is substantial, you must use external guides to prevent rod bending and manage side loads. Remember that air cushions only decelerate the piston near the end of travel; they do not act as a brake. If the load must be held vertically when air is lost, 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 SGC250X950 FAQ
The SGC250X950 delivers 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. It uses a G1 air port and features a 60 mm adjustable air cushion at both ends.
No, this specific SKU does not include a magnet. You must choose the -S variant to use CMSG, DMSG or EMSG switches. The four steel tie rods provide high rigidity, and it is dimensionally interchangeable per the ISO 15552 mounting interface.
