Airtac SGC Standard Cylinder SGC125X300H
The AirTAC Airtac SGC Standard Cylinder SGC125X300H is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 300mm 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 SGC125X300H
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles 300 mm strokes in demanding environments. The Viton H seal extends the operating range up to 150 C, making it suitable for hot processing lines. Four steel tie rods clamp the aluminum barrel to the covers for high rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life.
Because it lacks the -S magnet, this specific SKU cannot host CMSG, DMSG, or EMSG sensors. The G1/2 port and M27x2.0 rod thread are fixed by the 125 mm bore. For real-world sizing, plan for about 3682 N of actual work at 0.5 MPa, which lifts roughly 313 kg vertically with a 2:1 safety margin.

Where the Airtac SGC Standard Cylinder SGC125X300H Is Used
Hot End Glass Forming
Pushing 6136 N at 0.5 MPa, the Viton H seals survive ambient heat up to 150 C near lehr or annealing ovens where standard TPU seals would fail.
Engine Bay Actuation
The 300 mm stroke provides ample travel for opening large access panels or positioning heavy exhaust components during automated assembly tasks.
Heated Pallet Handling
With a safe working load around 3682 N, it easily diverts or lifts heavy pallets in drying rooms while the tie-rod construction maintains structural integrity.
Is the Airtac SGC Standard Cylinder SGC125X300H the Right Cylinder?
When sizing this 125 mm bore unit, compare it against its neighbors: the larger 160 mm bore provides 10053 N push at 0.5 MPa for heavier loads, while stepping down requires a non-SGC series as 125 mm is the smallest in this family. For this 300 mm stroke, ensure external guide rails are used to prevent rod bending under side loads.
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 stroke ends, so add an external rod lock or pilot-operated check valve if the load must be held in place.
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 SGC125X300H FAQ
The 125 mm bore yields a push of 6136 N and pull of 5734 N at 0.5 MPa, or 8590 N push and 8028 N pull at 0.7 MPa. The theoretical maximum force is 1251 kgf at 1.0 MPa. It uses a G1/2 air port and features a 32 mm rod with an M27x2.0 thread.
No, because this specific SKU lacks the -S suffix, it has no internal piston magnet and cannot accept CMSG, DMSG, or EMSG switches. You would need the SGC125X300HS variant for sensor compatibility. It remains fully dimensionally interchangeable per the ISO 15552 mounting interface.
