Airtac SGC Standard Cylinder SGC125X1100S
The AirTAC Airtac SGC Standard Cylinder SGC125X1100S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1100mm stroke, G1/2 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 SGC125X1100S
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is engineered for large-bore automation. Four steel tie rods clamp the aluminium barrel to the covers for high rigidity, while the two-way piston seal maintains an internal oil reservoir for extended service life. Plan for roughly 3682 N of real work at 0.5 MPa, which equates to lifting about 313 kg vertically with a 2:1 safety margin.
The -S suffix equips this 125 mm bore unit with a piston magnet for CMSG, DMSG, or EMSG position switches. It features a 32 mm rod, an M27x2.0 rod thread, a G1/2 air port, and 40 mm adjustable air cushions at both ends. Operating speeds span 30-500 mm/s across its 1100 mm travel.

Where the Airtac SGC Standard Cylinder SGC125X1100S Is Used
Pallet Transfer Line
Pushes heavy loaded pallets along a 1100 mm conveyor section, utilising the 6136 N thrust at 0.5 MPa to overcome rolling friction.
Automated Warehousing
Acts as a long-stroke diverter or pusher in distribution hubs, moving packages laterally between sorting lanes.
Press Ejection
Ejects formed metal parts from a large press bed, using the adjustable 40 mm cushions to soften the end-of-stroke impact.
Is the Airtac SGC Standard Cylinder SGC125X1100S the Right Cylinder?
This 1100 mm stroke sits well within the 1500 mm standard limit but demands careful mechanical integration. At this length, large-bore side loads induce rod bending; you must use an external guide or stopper to prevent premature seal wear and rod damage. If sizing thrust, the neighbouring SGC160 bore offers 10053 N push at 0.5 MPa, while the SGC125 remains the entry point for this series as no smaller bore exists.
Because it is a standard double-acting cylinder, the piston will drift if air pressure drops or the valve is centred. The end cushions only decelerate the stroke; they do not lock the load. Use an external rod lock or pilot-operated check valve for secure vertical 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 SGC125X1100S FAQ
This 125 mm bore cylinder has a G1/2 air port. It generates 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push and 8028 N pull at 0.7 MPa, and a theoretical maximum of 1251 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, dropping into existing large-bore fixtures. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors.
