Airtac SGC Standard Cylinder SGC125X2000STC
The AirTAC SGC Standard Cylinder SGC125X2000STC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 2000mm 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 SGC125X2000STC
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is engineered for large-bore automation tasks requiring an exceptionally long 2000 mm reach. Because 2000 mm exceeds the 1500 mm standard maximum, this SKU is supplied as a non-standard, made-to-order unit. The bore is 125 mm, the piston rod is 32 mm with an M27x2.0 thread, and the air port is G1/2. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life.
The -S suffix indicates a built-in piston magnet ready for CMSG, DMSG, or EMSG switches. The default TPU seal handles -20 to +70 C, with a Viton H option available for 0-150 C environments.

Where the Airtac SGC Standard Cylinder SGC125X2000STC Is Used
Automated Panel Transfer
Pushes large wood or composite panels down a 2-meter fabrication line using 6136 N of thrust at 0.5 MPa, relying on the TC trunnion to pivot smoothly under load.
High-Bay Material Handling
Extends 2000 mm to index heavy pallets into deep storage racks, utilizing the -S magnet and DMSG sensors to confirm full extension in automated warehouses.
Long-Stroke Press Feed
Feeds steel coil stock into a stamping press over a 2-meter distance, where the four steel tie rods maintain barrel alignment despite the extended stroke length.
Is the Airtac SGC Standard Cylinder SGC125X2000STC the Right Cylinder?
Choosing this specific 125 mm bore means sizing against its neighbors: step down to a smaller bore if your load is lighter, or step up to the 160 mm bore (which provides 10053 N push at 0.5 MPa) if you need more thrust. At 2000 mm, this cylinder is a non-standard made-to-order stroke that absolutely requires external guide support to prevent rod bending and excessive side-loading. The included TC trunnion mount utilizes the standardized ISO 15552 mounting interface, ensuring it drops into existing large-bore fixtures. Because it is a double-acting air cylinder, it will not hold a load if air pressure drops or the valve is centered; the piston will drift, so add an external rod lock or pilot-operated check valve for suspended loads.
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 SGC125X2000STC FAQ
At 0.5 MPa, this 125 mm bore cylinder provides 6136 N push and 5734 N pull. At 0.7 MPa, it delivers 8590 N push and 8028 N pull, with a theoretical maximum of 1251 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, speed is 30-500 mm/s, and it features a G1/2 port.
No, the double-acting piston will drift if air is exhausted or the valve is centered. The adjustable 40 mm air cushions only decelerate the piston near the end caps; they do not act as a brake. You must install an external rod lock or pilot-operated check valve to hold suspended loads safely.
