Airtac SGC Standard Cylinder SGC250X25S
The AirTAC Airtac SGC Standard Cylinder SGC250X25S 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 SGC250X25S
Delivering massive thrust for heavy industry, this double-acting ISO 15552 tie-rod cylinder generates 24543 N of push force and 23562 N of pull force at 0.5 MPa. The SGC250X25S features a robust 250 mm bore and a short 25 mm stroke, utilizing four steel tie rods to clamp the aluminum barrel to the covers for extreme rigidity under high loads. Because this is a Ø250 bore, the front-cover packing and buffer gasket use NBR seals rather than TPU, and a Viton H option extends operating temperatures up to 150 C.
Equipped with a built-in piston magnet (-S), the unit supports CMSG, DMSG, and EMSG switches for precise position detection. A G1 air port feeds the chamber, while the adjustable 60 mm air cushions at both ends absorb impact near stroke end. 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 heterogeneous two-way piston seal maintains an internal oil reservoir for long service life.

Where the Airtac SGC Standard Cylinder SGC250X25S Is Used
Heavy Press Stamping
Generates 34360 N of push force at 0.7 MPa to form thick steel plates in automated stamping presses.
Pallet Halting System
Uses the 50 mm piston rod and M42x2.0 thread to stop 1200 kg loaded pallets on heavy-duty assembly lines.
Scissor Lift Actuation
Provides the raw lifting power needed to raise industrial scissor platforms, safely handling loads around 1251 kg.
Is the Airtac SGC Standard Cylinder SGC250X25S 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 Ø200 bore which provides 15708 N of push force. The short 25 mm stroke is ideal for high-force clamping or pressing, but because a plain double-acting cylinder drifts when air is lost or a valve is centered, you must add an external rod lock or pilot-operated check valve to hold a suspended load safely. The integrated -S magnet allows seamless mounting of CMSG, DMSG, or EMSG sensors without extra hardware.
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 SGC250X25S FAQ
