Airtac SGC Standard Cylinder SGC125X15
The AirTAC Airtac SGC Standard Cylinder SGC125X15 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 15mm 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 SGC125X15
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder handles short-travel clamping and ejecting with precision. The SGC125X15 is built around a genuine ISO 15552 mounting interface, meaning it drops directly into standardized large-bore fixtures without redesigning your tooling. Four steel tie rods clamp the aluminium barrel to the covers, providing the high rigidity needed to withstand heavy thrust loads.
Because the stroke is just 15 mm, you should plan for about 3682 N of real work at 0.5 MPa, which lifts roughly 313 kg vertically with a 2:1 safety margin. The bore dictates a G1/2 air port and an M27x2.0 rod thread. Note that this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac SGC Standard Cylinder SGC125X15 Is Used
Heavy Stamping Clamp
Provides 6136 N of immediate clamping force to hold thick steel plates in place during a hydraulic stamping press cycle.
Press Ejector Pin
Uses the short 15 mm stroke to rapidly eject dense formed parts from a die before the automated extraction arm enters.
Injection Mold Lock
Secures heavy injection molding halved tools together with high thrust, utilizing the rigid four tie-rod build to resist deflection.
Is the Airtac SGC Standard Cylinder SGC125X15 the Right Cylinder?
Choosing this 125 mm bore makes sense when you need intense force in a tiny 15 mm travel distance. If your application requires less force, there is no smaller SGC bore available, so you would need to look at a different cylinder family entirely. Stepping up to the SGC160X15 raises the 0.5 MPa push force significantly to 10053 N. Since this is a non-magnetized SKU, you must use external mechanical limit switches for end-of-stroke detection. Furthermore, a standard cylinder drifts when air is lost or the valve is centered, so fit an external rod lock or pilot-operated check valve if the load must be held securely.
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 SGC125X15 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 of 1251 kgf at 1.0 MPa.
No, because this specific SKU does not include the -S magnet option. To use CMSG, DMSG, or EMSG switches, you must select the SGC125X15-S variant or rely on external mechanical sensors.
