Airtac SGC Standard Cylinder SGC250X800
The AirTAC Airtac SGC Standard Cylinder SGC250X800 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 800mm 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 SGC250X800
Delivering massive thrust for heavy industry, this double-acting ISO 15552 tie-rod cylinder generates 24543 N of push force at 0.5 MPa. Four steel tie rods clamp the aluminum barrel to the front and rear covers, ensuring high rigidity under extreme loads, while the two-way piston seal maintains an internal oil reservoir for long service life. Because this is a 250 mm bore, TPU seals are not offered; the front-cover packing and buffer gasket are NBR, with a Viton H option available for 0-150 C high-temperature environments.
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 unit features a 50 mm rod, a G1 air port, and an M42x2.0 rod thread. Note that this specific SKU lacks the -S magnet, meaning it cannot host CMSG, DMSG, or EMSG position switches without upgrading to the magnet-equipped variant.

Where the Airtac SGC Standard Cylinder SGC250X800 Is Used
Heavy Press Stamping
Drives large metal forming presses requiring up to 34360 N of push force at 0.7 MPa to shape thick steel plates.
Pallet Dispenser
Pushes heavy stacks of wooden pallets in automated distribution hubs, utilizing the 800 mm stroke for deep loading cycles.
Injection Mold Clamping
Secures large industrial molds during plastic injection, relying on the rigid four tie-rod construction to resist deflection.
Is the Airtac SGC Standard Cylinder SGC250X800 the Right Cylinder?
When sizing this 800 mm stroke actuator, consider stepping down to the 200 mm bore if your application only requires 15708 N of push at 0.5 MPa, as the 250 mm bore is the largest in the SGC family and maxes out the range. Because this is a large-bore cylinder with an 800 mm stroke, you must use external guide rails to prevent rod bending and absorb side loads. The adjustable 60 mm air cushions at both ends decelerate the piston near stroke end, but they do not function as a lock; if air is lost or the valve is centered, the piston will drift. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 SGC250X800 FAQ
This 250 mm bore cylinder features a G1 air port and an M42x2.0 rod thread. It 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 force of 5006 kgf at 1.0 MPa.
This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. It is dimensionally interchangeable per the ISO 15552 mounting interface, allowing it to drop into existing large-bore ISO 15552 fixtures and accessories.
