Airtac SGC Standard Cylinder SGC250X25
The AirTAC Airtac SGC Standard Cylinder SGC250X25 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 25mm 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 SGC250X25
Generating 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 aluminium barrel to the covers for high rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life. Because TPU is not offered for the Ø250 bore, the front-cover packing and buffer gasket use NBR instead.
With a G1 air port and a 25 mm stroke, 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. Note that this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position switches. The adjustable 60 mm air cushions at both ends decelerate the piston near stroke end to minimize impact.

Where the Airtac SGC Standard Cylinder SGC250X25 Is Used
Heavy Stamp Press Ejection
Provides the brute force needed to eject thick metal blanks from a 400-ton stamping press, utilizing the full 24543 N push at 0.5 MPa.
Injection Mold Separation
Breaks the vacuum and separates large industrial injection molding halves during the initial 25 mm opening stroke before the main robotic extractor takes over.
Pallet Stopper Gate
Acts as a high-force physical stop barrier in heavy-duty palletizing conveyors, halting loaded units weighing over a ton without bouncing.
Is the Airtac SGC Standard Cylinder SGC250X25 the Right Cylinder?
As the largest bore in the SGC family, there is no larger standard option; if 24543 N of push at 0.5 MPa is excessive, step down to the Ø200 bore, which provides 15708 N of push. Because this 25 mm stroke is very short, side-load risks are minimal, but ensure the mounting arrangement—whether LB foot, FA/FB flange, or TC trunnion—aligns perfectly with the load. Remember that a plain cylinder drifts when air is lost or the valve is centred; the air cushion only decelerates the piston and does not act as a brake, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended load.
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 SGC250X25 FAQ
The SGC250X25 delivers 24543 N push and 23562 N pull at 0.5 MPa, or 34360 N push and 32986 N pull at 0.7 MPa. The theoretical maximum force is 5006 kgf at 1.0 MPa. It features a G1 air port and a 50 mm piston rod.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so it drops directly into standard large-bore fixtures. However, because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG switches; you would need the SGC250X25-S variant for sensing.
