Airtac SGC Standard Cylinder SGC250X1800S
The AirTAC Airtac SGC Standard Cylinder SGC250X1800S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 1800mm 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 SGC250X1800S
Delivering massive thrust for heavy industry, this double-acting ISO 15552 tie-rod cylinder generates 24543 N of push force at 0.5 MPa. Because the 1800 mm stroke exceeds the 1500 mm standard limit, it is manufactured as a made-to-order unit. Four steel tie rods clamp the aluminium barrel to the covers, ensuring high structural rigidity under extreme loads, while the two-way piston seal maintains an internal oil reservoir for long service life.
Equipped with a G1 air port and a Ø50 mm piston rod, the bore uses an NBR front-cover packing and buffer gasket since TPU is not offered for Ø250. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG switches. Plan for roughly 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 SGC250X1800S Is Used
Automotive Press Ejection
Provides the heavy push force needed to eject large formed panels from hydraulic presses over the extended 1800 mm travel distance.
Palletizer Strapping Arm
Drives a massive strapping and positioning arm across heavy-duty palletizing stations, utilizing the G1 port for high-volume air flow.
Large Mold Transfer
Shifts heavy industrial molds between machining centers, relying on the rigid steel tie-rod construction to handle extreme weights.
Is the Airtac SGC Standard Cylinder SGC250X1800S the Right Cylinder?
Sizing this actuator requires careful load evaluation since it sits at the top of the SGC range with no larger bore available. If the 24543 N push at 0.5 MPa is excessive, dropping down to the Ø200 bore provides 15708 N. Because the 1800 mm length is non-standard, you must account for extended rod-bending risks and incorporate external guide rails to prevent side-load damage.
The air cushions only decelerate the piston near the stroke ends and do not act as a brake. If the load must remain suspended when air is removed or the valve is centered, install an external rod lock or a pilot-operated check valve to prevent drifting.
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 SGC250X1800S FAQ
This double-acting cylinder delivers 24543 N push and 23562 N pull at 0.5 MPa, and 34360 N push and 32986 N pull at 0.7 MPa. The theoretical maximum force is 5006 kgf at 1.0 MPa. It operates at 30-500 mm/s, accepts pressure from 0.15-1.0 MPa, and features a G1 port with a 60 mm adjustable air cushion at both ends.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so it drops directly into standard large-bore fixtures. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches. Note that because the 1800 mm stroke is non-standard, you should verify mounting dimensions and add external guides to support the rod.
