Airtac SGC Standard Cylinder SGC125X1300
The AirTAC Airtac SGC Standard Cylinder SGC125X1300 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1300mm 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 SGC125X1300
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles large-bore automation tasks over its 1300 mm stroke. 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 to maximize service life. 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.
This specific SKU lacks the -S magnet, meaning it cannot host CMSG, DMSG, or EMSG position switches. Fluid supply connects via a G1/2 port, and the standard TPU seals support a temperature range of -20 to +70 C. For high-heat environments up to 150 C, a Viton H seal option is available.

Where the Airtac SGC Standard Cylinder SGC125X1300 Is Used
Long-Stroke Material Transfer
Pushes heavy pallets across a 1.3-meter span between machining centers using 6136 N of thrust at 0.5 MPa.
Vertical Lift Gate Actuation
Raises and lowers industrial loading dock gates, safely managing loads up to 313 kg with proper external guidance.
Automated Press Ejection
Ejects large formed parts from hydraulic presses, relying on the rigid tie-rod build to withstand high impact forces.
Is the Airtac SGC Standard Cylinder SGC125X1300 the Right Cylinder?
When sizing this 125 mm bore unit, compare its 6136 N push force at 0.5 MPa against your actual load requirements. If you need substantially more power, stepping up to the 160 mm bore yields 10053 N, while this 125 mm model serves as the entry point into the large-bore SGC family. Because this is a plain cylinder without a magnet, you cannot mount reed or solid-state sensors directly; if your sequence requires position feedback, select the -S variant instead.
With a 1300 mm stroke, the extended rod is highly susceptible to bending under side loads. Always use an external guide or linear bearing to support the load and prevent rod damage. Furthermore, the adjustable air cushions only decelerate the piston near the end caps; they do not act as a brake. If the application must hold a vertical load when air is removed or the valve is centered, install an external rod lock or a pilot-operated check valve to prevent drifting.
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 SGC125X1300 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, increasing to 8590 N push and 8028 N pull at 0.7 MPa. The theoretical maximum force is 1251 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet. You must choose the -S variant to mount CMSG, DMSG, or EMSG switches. The unit is dimensionally interchangeable per the ISO 15552 mounting interface, allowing it to drop into existing large-bore fixtures.
