Airtac SGC Standard Cylinder SGC250X350
The AirTAC Airtac SGC Standard Cylinder SGC250X350 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 350mm 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 SGC250X350
Delivering 24543 N of push force at 0.5 MPa, this double-acting tie-rod cylinder handles the most demanding large-bore tasks in the AirTAC range. It is dimensionally interchangeable per the ISO 15552 mounting interface, dropping directly into existing heavy fixtures. Four steel tie rods clamp the aluminum barrel to the covers for extreme rigidity, while a two-way piston seal maintains an internal oil reservoir for long service life.
Because this is a Ø250 bore, TPU seals are not available; the front-cover packing and buffer gasket utilize NBR instead, with a Viton H option for 0-150 C high-temperature environments. Plan for about 14726 N of real work at 0.5 MPa, which lifts roughly 1251 kg vertically with a 2:1 safety margin. This specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac SGC Standard Cylinder SGC250X350 Is Used
Heavy Stamp Pressing
Supplies up to 34360 N of thrust at 0.7 MPa to drive large metal forming and stamping dies in automotive body panel lines.
Pallet Lift Gates
Raises industrial scissor lift tables, easily moving 1251 kg loads vertically through a 350 mm cycle with a safe 2:1 margin.
Injection Mold Clamping
Secures heavy injection molding halves, utilizing the rigid four steel tie-rod construction to withstand massive 5006 kgf peak forces.
Is the Airtac SGC Standard Cylinder SGC250X350 the Right Cylinder?
When sizing this 350 mm stroke model, verify if the 160 mm bore (offering 10053 N push at 0.5 MPa) is insufficient, as the SGC250 is the largest available in this series with no larger standard option. For any stroke at or above 350 mm, carefully evaluate side loads and use external guide rails to prevent rod bending under heavy extension. This non-magnetized version cannot host sensors; choose an SGC250X350-S variant if CMSG, DMSG, or EMSG switches are required.
Remember that the adjustable 60 mm air cushions only decelerate the piston near the stroke ends and do not act as a brake. If the machinery loses air pressure or the valve is centered, the piston will drift; specify an external rod lock or a pilot-operated check valve for applications requiring strict 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 SGC250X350 FAQ
The SGC250X350 features a G1 air port and an M42x2.0 rod thread. It generates a push force of 24543 N and a pull force of 23562 N at 0.5 MPa. At 0.7 MPa, push is 34360 N and pull is 32986 N. The theoretical maximum force is 5006 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet. You must select the SGC250X350-S variant to use CMSG, DMSG, or EMSG magnetic switches. Additionally, its ISO 15552 mounting interface ensures it matches standard large-bore fixtures, and the NBR seals can be swapped for Viton H in high-temperature settings.
