Airtac SGC Standard Cylinder SGC250X900SH
The AirTAC Airtac SGC Standard Cylinder SGC250X900SH is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 900mm 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 SGC250X900SH
Delivering massive thrust for heavy industry, this 250 mm bore double-acting cylinder pushes with 24543 N and pulls with 23562 N at 0.5 MPa. Four steel tie rods clamp the aluminium barrel to the covers for exceptional rigidity under such large forces, while the two-way piston seal maintains an internal oil reservoir for sustained lubrication. Because the -H suffix specifies Viton FKM seals, the operating range extends from -20 up to 150 C, making it suitable for high-temperature environments where standard elastomers fail.
For practical sizing, plan for about 14726 N of real work at 0.5 MPa, which equates to lifting roughly 1251 kg vertically with a 2:1 safety margin. The G1 air port feeds the 50 mm chrome-plated rod, and the -S magnet enables CMSG, DMSG, or EMSG position switches. Note that on this 250 bore, TPU seals are unavailable; the front-cover packing and buffer gasket rely on NBR as standard, here upgraded to Viton.

Where the Airtac SGC Standard Cylinder SGC250X900SH Is Used
Automotive Press Transfer
Moves heavy stamped body panels between die stations, utilising the 34360 N push force at 0.7 MPa to reliably shift heavy platens over the 900 mm travel.
Foundry Mold Closing
Leverages the Viton H high-temperature seals to withstand radiant heat up to 150 C while applying massive clamping pressure on resin casting molds.
Steel Coil Handling
Actuates large lifting arms in a mill environment, where the built-in magnet allows CMSG sensors to confirm full extension despite the harsh industrial setting.
Is the Airtac SGC Standard Cylinder SGC250X900SH the Right Cylinder?
Sizing downward from this 250 mm bore, the 200 mm option provides 15708 N push at 0.5 MPa, whereas the 250 is the largest in the SGC family, topping out at a theoretical 5006 kgf at 1.0 MPa. Because this model features a 900 mm stroke, external guide rails are strongly recommended to prevent rod bending and absorb side loads during long extensions. If the application requires the load to remain suspended when air pressure drops or the valve is centred, the piston will drift; the adjustable 60 mm air cushions only decelerate the stroke end and do not function as a brake. You must add an external rod lock or a pilot-operated check valve for secure 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 SGC250X900SH FAQ
At 0.5 MPa it pushes 24543 N and pulls 23562 N; at 0.7 MPa it pushes 34360 N and pulls 32986 N. The theoretical maximum force is 5006 kgf at 1.0 MPa. It uses a G1 air port, a 50 mm piston rod with an M42x2.0 thread, and operates at 30-500 mm/s.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so it fits standard large-bore foot, flange, and trunnion accessories. The -S suffix means a magnet is built in, allowing you to mount CMSG, DMSG, or EMSG switches directly to the barrel for position detection.
