Airtac SGC Standard Cylinder SGC125X260
The AirTAC Airtac SGC Standard Cylinder SGC125X260 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 260mm 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 SGC125X260
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder is built for heavy-duty automation. Four steel tie rods clamp the aluminium barrel to the front and rear covers, providing the high rigidity needed to handle large thrust loads, while a two-way piston seal maintains an internal oil reservoir for long service life. The G1/2 air port and M27x2.0 rod thread streamline integration into existing pneumatic setups.
Because it shares the standardized ISO 15552 mounting interface, this unit drops directly into existing large-bore fixtures without custom bracketry. For practical sizing, plan for about 3682 N of real work at 0.5 MPa, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin. Note that this specific SKU lacks the -S magnet, so it cannot support CMSG, DMSG, or EMSG position switches.

Where the Airtac SGC Standard Cylinder SGC125X260 Is Used
Press Fit Assembly
Drives small bushings and bearings into automotive transmission housings, utilizing the 6136 N push force at 0.5 MPa to seat components reliably.
Pallet Stopper Gate
Acts as a heavy-duty physical stop barrier on roller conveyors, using its 260 mm stroke to extend and halt loaded pallets weighing up to 313 kg.
Plastic Mould Ejection
Provides the robust ejection stroke required to push large formed plastic parts out of injection moulding machines at the end of the cooling cycle.
Is the Airtac SGC Standard Cylinder SGC125X260 the Right Cylinder?
When sizing this 125 mm bore option, compare it against its neighbours: stepping down is not possible as this is the smallest SGC bore, but stepping up to the 160 mm bore raises the push force to 10053 N at 0.5 MPa if your application demands more power. With a 260 mm stroke, verify that your load guide can handle the side-load forces to prevent rod bending, as longer strokes increase the risk of mechanical deflection. This non-magnet model cannot hold a position signal; if sensing is required, select the -S variant. Furthermore, the standard air cushion only decelerates the piston near the stroke end and does not act as a brake—install an external rod lock or pilot-operated check valve if the load must be held vertically when air pressure is lost.
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 SGC125X260 FAQ
This 125 mm bore cylinder features a G1/2 air port and delivers a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push increases to 8590 N and the pull to 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa.
You can use any standard ISO 15552 mounting accessories, such as LB foot or FA flange brackets, because the tie-rod dimensions match the interface exactly. However, because this specific SKU lacks the -S magnet option, it cannot accommodate CMSG, DMSG, or EMSG magnetic switches.
