Airtac SGC Standard Cylinder SGC250X25STC
The AirTAC Airtac SGC Standard Cylinder SGC250X25STC 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 SGC250X25STC
Delivering massive thrust in a compact footprint, this double-acting tie-rod cylinder generates 24543 N of push force at 0.5 MPa. The Ø250 bore uses a G1 air port and a Ø50 mm piston rod, while four steel tie rods clamp the aluminum barrel to the covers for extreme structural rigidity under heavy loads. Because the stroke is only 25 mm, the TC trunnion mounting allows seamless integration into pivot-driven machinery without projecting too far into the work cell.
For practical sizing, plan for about 14726 N of real work at 0.5 MPa, which safely lifts roughly 1251 kg vertically with a 2:1 margin. The built-in magnet (-S) directly supports CMSG, DMSG, and EMSG position switches. Note that TPU seals are not offered on this large bore; the front-cover packing and buffer gasket utilize NBR instead, with a Viton H option available for 0-150 C high-temperature environments.

Where the Airtac SGC Standard Cylinder SGC250X25STC Is Used
Heavy Stamping Presses
Provides the intense short-stroke clamping force needed to hold thick steel plates stationary inside an automotive stamping die.
Injection Molding Ejectors
Uses the 23562 N pull force at 0.5 MPa to break loose and eject dense plastic or composite parts from deep mold cavities.
Pallet Stopper Gates
Acts as a high-impact physical barrier in automated conveyor lines, halting fully loaded pallets weighing over a ton before they reach the wrapping station.
Is the Airtac SGC Standard Cylinder SGC250X25STC the Right Cylinder?
As the largest bore in the SGC family, there is no larger standard size to step up to if the 24543 N push at 0.5 MPa proves insufficient. If you require less force, stepping down to the Ø200 bore drops the output to 15708 N. This short 25 mm stroke keeps the rod fully supported, minimizing side-load risks inherent to longer extensions. Remember that an unpowered cylinder cannot hold a load in place; if air is lost or the valve is centered, the piston will drift. You must add an external rod lock or a pilot-operated check valve for secure vertical load holding.
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 SGC250X25STC FAQ
This Ø250 bore model features a G1 air port and delivers 24543 N push / 23562 N pull at 0.5 MPa, 34360 N push / 32986 N pull at 0.7 MPa, and a theoretical maximum of 5006 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, allowing you to use standard foot, flange, clevis, or TC trunnion hardware. The included -S magnet enables direct fitting of CMSG, DMSG, or EMSG electronic or reed switches.
