Airtac SGC Standard Cylinder SGC125X1750S
The AirTAC Airtac SGC Standard Cylinder SGC125X1750S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1750mm 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 SGC125X1750S
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles large-bore automation tasks. Its 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 mechanical life. Because this specific 1750 mm length exceeds the 1500 mm standard maximum, it is manufactured as a made-to-order unit.
Plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin. The G1/2 air port and M27x2.0 rod thread match the 125 mm bore standard. The included -S piston magnet enables CMSG, DMSG, or EMSG switches for position sensing.

Where the Airtac SGC Standard Cylinder SGC125X1750S Is Used
Automated Pallet Transfer
Pushes heavy pallets along an extended assembly line using its 1750 mm reach, relying on the 6136 N thrust to overcome friction over the long travel distance.
High-Bay Storage Extraction
Extracts totes from deep storage racking where a standard 1500 mm stroke falls short, using the -S magnet to confirm full extension.
Large Press Loading
Feeds heavy steel blanks into a hydraulic press, utilizing the rigid ISO 15552 tie-rod construction to maintain alignment under high dynamic loads.
Is the Airtac SGC Standard Cylinder SGC125X1750S the Right Cylinder?
When sizing this 125 mm bore against the SGC family, stepping down is not an option as it is the smallest available size. Stepping up to the 160 mm bore increases thrust to 10053 N at 0.5 MPa. Because this 1750 mm unit is a non-standard made-to-order stroke, verify your delivery timeline. For any stroke at or beyond 500 mm, you must use external guides to prevent rod bending and manage side loads.
Remember that a standard double-acting cylinder drifts when air is removed or a valve centers; the adjustable 40 mm air cushions only decelerate the piston near the end caps and do not act as a locking brake. To suspend a load safely, 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 SGC125X1750S FAQ
This 125 mm bore cylinder features a G1/2 air port and delivers 6136 N push / 5734 N pull at 0.5 MPa, 8590 N push / 8028 N pull at 0.7 MPa, with a theoretical maximum of 1251 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, allowing you to use standard LB foot, FA flange, or TC trunnion fixtures. The four steel tie rods provide the structural rigidity needed for this non-standard 1750 mm stroke.
