Airtac SGC Standard Cylinder SGC125X800STC
The AirTAC Airtac SGC Standard Cylinder SGC125X800STC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 800mm 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 SGC125X800STC
Delivering 6136 N of push force at 0.5 MPa, this double-acting tie-rod cylinder brings massive thrust to automated lines. Its four steel tie rods clamp the aluminum barrel securely to the covers, ensuring high rigidity under heavy loads, while the two-way piston seal maintains an internal oil reservoir for long service life. Because of its standardized dimensions, it drops directly into existing ISO 15552 mounting fixtures, making upgrades or spares replacement straightforward.
Equipped with a built-in piston magnet (-S), this unit supports CMSG, DMSG, and EMSG electronic or reed switches for precise end-of-stroke detection. The G1/2 air port and M27x2.0 rod thread match the 125 mm bore standard, and adjustable 40 mm air cushions at both ends protect the mechanics from endcap impact. For practical sizing, plan for about 3682 N of real work at 0.5 MPa, or roughly 313 kg lifted vertically with a 2:1 safety margin.

Where the Airtac SGC Standard Cylinder SGC125X800STC Is Used
Pallet Transfer Diversion
Pushes heavy loaded pallets sideways onto secondary conveyor lines, utilizing the 6136 N thrust and 800 mm reach to clear the main belt without collision.
Automated Warehousing Gates
Actuates large security or environmental partition doors in high-throughput logistics centers, where the TC trunnion mount absorbs frame shifts during the long 800 mm travel.
Injection Mold Ejection
Drives large secondary ejection plates for heavy plastic parts, relying on the built-in magnet and EMSG sensors to confirm full stroke completion before the mold closes.
Is the Airtac SGC Standard Cylinder SGC125X800STC the Right Cylinder?
Choosing this 125 mm bore over the 160 mm option (which yields 10053 N push at 0.5 MPa) is ideal when the smaller unit safely covers your load, whereas dropping below 125 mm is impossible within the SGC family as it is the smallest available size. The included TC trunnion mount provides a pivoting centerline axis that handles lateral rod stress better than rigid flanges, which is highly recommended for this 800 mm stroke. At this extended length, always use an external guide or stopper to prevent rod bending and premature seal wear caused by side loads. Remember that a standard cylinder will drift and drop its load if air pressure is lost or the valve is centered; the air cushion only decelerates the piston near the end of travel and does not act as a brake. For suspended or vertical loads, install an external rod lock or a pilot-operated check valve.
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 SGC125X800STC FAQ
At 0.5 MPa, this 125 mm bore cylinder provides 6136 N push and 5734 N pull force. At 0.7 MPa, it delivers 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa. It uses a G1/2 air port and an M27x2.0 rod thread.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, meaning it accepts standard ISO 15552 foot, flange, clevis, or trunnion hardware. This specific SKU includes the -S magnet, allowing you to mount CMSG, DMSG, or EMSG sensors directly into the barrel groove for position detection.
