Airtac SGC Standard Cylinder SGC250X30S
The AirTAC Airtac SGC Standard Cylinder SGC250X30S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 30mm 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 SGC250X30S
Delivering 24543 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles the heaviest automation tasks. Four steel tie rods clamp the aluminium barrel to the covers for extreme rigidity under massive thrust. The G1 air port and M42x2.0 rod thread match the large 250 mm bore. Because the -S suffix denotes a built-in magnet, you can mount CMSG, DMSG, or EMSG switches for precise end-position detection.
For real-world sizing, plan for about 14726 N of usable work at 0.5 MPa, which safely lifts roughly 1251 kg vertically with a 2:1 margin. Note that TPU seals are unavailable for this bore; the front-cover packing and buffer gasket utilize NBR instead, with a Viton H option for 0-150 C environments. The two-way piston seal retains an oil reservoir to maximize operational lifespan.

Where the Airtac SGC Standard Cylinder SGC250X30S Is Used
Heavy Press Stamping
Generates up to 34360 N at 0.7 MPa to form thick steel plates in automated stamping presses.
Pallet Stopper Gate
Acts as a high-force pneumatic stop in conveyor systems, halting 1251 kg loaded pallets reliably.
Injection Mold Clamping
Provides rigid short-stroke clamping force for large industrial injection molding machinery.
Is the Airtac SGC Standard Cylinder SGC250X30S the Right Cylinder?
Choosing this 30 mm stroke model is ideal when massive clamping or short ejection is needed without a long overhang. If your application requires less force, the next size down is the 200 mm bore, providing 15708 N push at 0.5 MPa; there is no larger standard SGC bore above 250 mm. Because the stroke is under 500 mm, rod bending stress is minimal, but always guide the load externally to prevent side-loading damage.
Remember that a standard pneumatic cylinder drifts when air is lost or the valve is centered, as the adjustable 60 mm air cushions only decelerate the piston near stroke ends rather than locking it. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve into your fixture.
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 SGC250X30S FAQ
The 250 mm bore features a G1 air port and M42x2.0 rod thread. 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.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, dropping directly into existing large-bore fixtures. The tie-rod build adds rigidity, and the -S magnet supports CMSG, DMSG, and EMSG sensors.
