Airtac SGC Standard Cylinder SGC125X240
The AirTAC Airtac SGC Standard Cylinder SGC125X240 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 240mm 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 SGC125X240
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder brings serious power to automated lines. The 125 mm bore uses a G1/2 air port and a 32 mm hard-chrome piston rod. Four steel tie rods clamp the aluminium barrel to the covers, ensuring high structural rigidity under heavy thrust. The two-way piston seal retains an internal oil reservoir for continuous lubrication and extended service life.
Because it follows the standardized ISO 15552 mounting interface, this model drops directly into existing large-bore fixtures without custom bracketry. At 0.5 MPa you can plan for roughly 3682 N of actual work, which translates to lifting about 313 kg vertically with a 2:1 safety margin. Note that this specific SKU lacks the -S magnet, so it cannot host CMSG, DMSG, or EMSG position switches.

Where the Airtac SGC Standard Cylinder SGC125X240 Is Used
Pallet Diversion
Pushes heavy timber pallets sideways onto a secondary packaging line using its 6136 N thrust capacity.
Stacker Ejection
Ejects compressed cardboard bales from a vertical baler, utilizing the 240 mm stroke to clear the press bed.
Press Ejection
Kicks formed aluminum parts out of a hydraulic press, relying on the rigid tie-rod frame to absorb shock.
Is the Airtac SGC Standard Cylinder SGC125X240 the Right Cylinder?
When sizing this unit, compare its 6136 N push @0.5 MPa against your actual load requirements. If your application needs less force, there is no smaller bore in the SGC family; you would need to look at a different AirTAC series. If you need more power, stepping up to the 160 mm bore yields 10053 N @0.5 MPa. Since this is a 240 mm stroke, mounting stability is generally straightforward, but always support the load to minimize rod side-loading. Remember that a standard cylinder drifts when air is lost or a valve is centered; the adjustable 40 mm air cushions only decelerate the piston near the end caps. For strict load holding, 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 SGC125X240 FAQ
This 125 mm bore cylinder features a G1/2 air port. 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 magnet. You must select the -S variant (SGC125X240-S) to use CMSG, DMSG, or EMSG magnetic switches. The standard ISO 15552 mounting interface and four tie rods remain identical across both versions.
