Airtac SGC Standard Cylinder SGC125X290
The AirTAC Airtac SGC Standard Cylinder SGC125X290 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 290mm 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 SGC125X290
Generating 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder brings serious thrust to demanding pneumatic setups. Four steel tie rods clamp the aluminium barrel to the covers for high structural rigidity, while the two-way piston seal maintains an internal oil reservoir to prolong service life.
Because it follows the standardized ISO 15552 mounting interface, it drops directly into existing large-bore fixtures without custom brackets. Plan for roughly 3682 N of real work at 0.5 MPa, which translates to lifting about 313 kg vertically with a 2:1 safety margin. This base SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without switching to the -S version.

Where the Airtac SGC Standard Cylinder SGC125X290 Is Used
Press Fit Assembly
Drives bearings into heavy housings on an automated line, utilizing the 6136 N push force at 0.5 MPa to seat components reliably.
Pallet Stopper Gate
Acts as a heavy-duty pneumatic stop for 300 kg loaded pallets, using the 290 mm stroke to clear the conveyor path for indexing.
Plastic Mould Ejection
Ejects large formed plastic parts from stationary moulds, relying on the rigid tie-rod construction to withstand repetitive high-impact cycles.
Is the Airtac SGC Standard Cylinder SGC125X290 the Right Cylinder?
When sizing this 125 mm bore unit, verify whether the 6136 N at 0.5 MPa provides enough thrust, or if you should step up to the 160 mm bore (10053 N). If you are overspeeding and need less impact, dropping down is not an option as 125 mm is the smallest SGC size available. The 290 mm stroke falls below the 500 mm threshold, so standard rod-bending concerns are minimal, though side loads should still be minimized through proper guiding.
Remember that the adjustable air cushion at each end only decelerates the piston near the stroke limits; it does not act as a brake. If the application requires the load to stay put when air is removed or the valve is centred, you must add an external rod lock or a pilot-operated check valve to prevent drift.
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 SGC125X290 FAQ
This 125 mm bore cylinder features a G1/2 air port and an M27x2.0 rod thread. It generates 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.
No, this specific SKU does not include a piston magnet, so it cannot accept CMSG, DMSG or EMSG switches. You must specify the -S variant (SGC125X290-S) if your application requires electronic position sensing.
