Airtac SGC Standard Cylinder SGC250X950S
The AirTAC Airtac SGC Standard Cylinder SGC250X950S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 950mm 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 SGC250X950S
Delivering massive thrust for heavy industrial tasks, this double-acting ISO 15552 tie-rod cylinder pushes with 24543 N and pulls with 23562 N at 0.5 MPa. Four steel tie rods clamp the aluminum barrel to the covers for high rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life. Plan for about 14726 N of real work at 0.5 MPa, which safely lifts roughly 1251 kg vertically with a 2:1 margin.
Because this SKU includes the -S magnet, it directly supports CMSG, DMSG, and EMSG position switches. The Ø250 bore uses a G1 air port, an M42x2.0 rod thread, and a 60 mm adjustable air cushion at both ends. Note that TPU seals are not offered on this bore; the front-cover packing and buffer gasket are NBR, with a Viton H high-temperature option available for 0-150 C environments.

Where the Airtac SGC Standard Cylinder SGC250X950S Is Used
Heavy Press Demolding
Provides the 24543 N push force needed to break large rubber or composite molds free in automotive pressing lines.
Pallet Displacement
Utilizes the 950 mm stroke to push heavy loaded pallets laterally across high-capacity transfer decks.
Large Roll Handling
Lifts industrial paper or steel rolls weighing up to 1251 kg vertically using the 2:1 safe working margin.
Is the Airtac SGC Standard Cylinder SGC250X950S the Right Cylinder?
When sizing this 250 mm bore unit, compare its 24543 N push force at 0.5 MPa against the smaller Ø200 bore, which yields 15708 N under the same pressure. As the largest SGC option, there is no larger standard bore to step up to if 34360 N at 0.7 MPa is insufficient. The 950 mm stroke demands external guidance to prevent rod bending under side loads, so use linear rails or guides to support the massive piston rod during extension.
The integrated magnet enables CMSG, DMSG, and EMSG sensors for end-position detection. Remember that the adjustable cushion only decelerates the piston near stroke end and does not act as a brake; if air pressure drops, the piston will drift. Install an external rod lock or pilot-operated check valve to hold suspended loads safely.
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 SGC250X950S FAQ
At 0.5 MPa it pushes with 24543 N and pulls with 23562 N. At 0.7 MPa the push is 34360 N and the pull is 32986 N. The theoretical maximum force is 5006 kgf at 1.0 MPa. This 250 mm bore model uses a G1 air port.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so it drops into standard large-bore fixtures. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG electronic and reed switches.
