Airtac SGC Standard Cylinder SGC125X35S
The AirTAC Airtac SGC Standard Cylinder SGC125X35S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 35mm 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 SGC125X35S
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is built for large-bore automation. Four steel tie rods clamp the aluminum barrel to the covers for high rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life. 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 built-in -S piston magnet allows direct mounting of CMSG, DMSG, or EMSG switches for position sensing. It features a 125 mm bore, a 35 mm stroke, a G1/2 air port, and an M27x2.0 rod thread. Standard TPU seals handle temperatures from -20 to +70 C, with Viton H available for 0-150 C environments.

Where the Airtac SGC Standard Cylinder SGC125X35S Is Used
Press Ejection
Uses the 6136 N push force at 0.5 MPa to eject stamped metal parts from a press bed in automated fabrication lines.
Pallet Stops
Acts as a high-force pneumatic stop for heavy pallets on roller conveyors, relying on the 125 mm bore to halt momentum.
Clamp Actuation
Secures heavy steel workpieces during machining operations, utilizing the 35 mm stroke for rapid clamping cycles.
Is the Airtac SGC Standard Cylinder SGC125X35S the Right Cylinder?
This 125 mm bore sits at the entry point of the SGC large-bore family; if you need less force, you must step down to a smaller non-SGC series, while stepping up to the 160 mm bore raises push force to 10053 N at 0.5 MPa. Because this SKU includes the -S magnet, it is ready for CMSG, DMSG, or EMSG sensors. Remember that a standard cylinder drifts when air is lost or a valve is centered, as the air cushion only decelerates the piston near stroke end. For suspended loads, add 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 SGC125X35S FAQ
This 125 mm bore cylinder features a G1/2 air port and an M27x2.0 rod thread. It delivers 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push and 8028 N pull at 0.7 MPa, with a theoretical maximum force of 1251 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so it drops into the same fixtures as any standard ISO 15552 large-bore cylinder. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors.
