Airtac SGC Standard Cylinder SGC250X900S
The AirTAC Airtac SGC Standard Cylinder SGC250X900S 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 SGC250X900S
Generating a massive 24543 N of push force at 0.5 MPa, this double-acting large-bore ISO 15552 tie-rod cylinder is built for the most demanding industrial presses. Four steel tie rods clamp the aluminium barrel to the front and rear covers, ensuring high structural rigidity while the two-way piston seal maintains an internal oil reservoir for long service life. Because this is a Ø250 bore, TPU seals are not available; instead, the front-cover packing and buffer gasket utilise NBR, with a Viton H option for high-temperature environments up to 150 C.
The built-in piston magnet (-S) directly supports CMSG, DMSG, and EMSG position switches, enabling precise end-of-stroke detection in automated machinery. 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 unit features a G1 air port, an M42x2.0 rod-end thread, and 60 mm adjustable air cushions at both ends to decelerate the heavy payload smoothly.

Where the Airtac SGC Standard Cylinder SGC250X900S Is Used
Heavy-Duty Metal Stamping
Provides the 34360 N push force at 0.7 MPa required to drive large stamping dies and form thick steel plates in automotive body panel production lines.
Automated Pallet Handling
Utilises its 900 mm stroke and 1251 kg vertical lift capacity to push fully loaded heavy-duty pallets onto transfer carousels in high-throughput distribution centres.
Large Injection Mould Extraction
Leverages the CMSG/DMSG/EMSG sensor magnet and robust tie-rod construction to extract bulky plastic automotive interior panels from 1000-ton injection moulding machines.
Is the Airtac SGC Standard Cylinder SGC250X900S the Right Cylinder?
When sizing this 900 mm stroke actuator, consider the neighbouring SGC200 bore if your load is lighter, as it provides 15708 N of push at 0.5 MPa; the SGC250 is the largest available in this series, offering a maximum theoretical output of 5006 kgf at 1.0 MPa. Because this model features a substantial 900 mm stroke, external guide rails are strongly recommended to prevent rod bending and excessive side loading under such a long extension.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centred, as the air cushion only decelerates the piston near the stroke end and acts purely as an end-of-stroke buffer, never a brake. To safely suspend a vertical load, 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 SGC250X900S FAQ
This double-acting cylinder delivers 24543 N push and 23562 N pull at 0.5 MPa, increasing to 34360 N push and 32986 N pull at 0.7 MPa, with a theoretical maximum of 5006 kgf at 1.0 MPa. It features a 250 mm bore, a 900 mm stroke, a G1 air port, an M42x2.0 rod thread, and operates at speeds between 30-500 mm/s.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, allowing it to drop directly into existing large-bore fixtures using standard LB foot, FA flange, or TC trunnion brackets. Additionally, the included -S piston magnet enables direct mounting of CMSG, DMSG, and EMSG reed or electronic switches for position sensing.
