Airtac SGC Standard Cylinder SGC250X290S
The AirTAC Airtac SGC Standard Cylinder SGC250X290S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 290mm 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 SGC250X290S
Delivering massive thrust for heavy industry, this double-acting tie-rod cylinder pushes with 24543 N at 0.5 MPa. Because it is dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures without redesign. The robust construction uses four steel tie rods to clamp the aluminum barrel to the covers, ensuring high rigidity under extreme loads. A two-way piston seal maintains an internal oil reservoir for long mechanical life.
As a 250 mm bore unit, the front-cover packing and buffer gasket are NBR (TPU is not offered at this size), with a Viton H option available for 0-150 C high-temperature environments. The 290 mm stroke operates at 30-500 mm/s, and the -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG switches. Plan for around 14726 N of real work at 0.5 MPa, which safely lifts about 1251 kg vertically with a 2:1 margin.

Where the Airtac SGC Standard Cylinder SGC250X290S Is Used
Heavy Press Stamping
Drives large press dies requiring 24543 N of push force at 0.5 MPa for forming thick steel plates.
Palletizer Actuation
Lifts heavy unit loads vertically, easily handling components weighing up to 1251 kg with a safe 2:1 margin.
Injection Mold Clamping
Holds large industrial molds securely in place using the 34360 N push force available at 0.7 MPa.
Is the Airtac SGC Standard Cylinder SGC250X290S the Right Cylinder?
Choosing this 290 mm stroke means sizing neighbors correctly: the 200 mm bore provides 15708 N push at 0.5 MPa, while there is no larger standard SGC bore above 250 mm. For any stroke approaching or exceeding 500 mm, you must support the load with external guides to prevent rod bending and premature seal wear. The 60 mm adjustable air cushions at both ends only decelerate the piston near stroke end; they do not act as a brake. If the machinery loses air or the valve centers, the piston will drift, so fit an external rod lock or pilot-operated check valve for suspended loads.
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 SGC250X290S 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 of 5006 kgf at 1.0 MPa.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches. Additionally, its ISO 15552 mounting interface ensures dimensional interchangeability with other standard large-bore fixtures and accessories.
