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.
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.
