Airtac SGC Standard Cylinder SGC125X70SN
The AirTAC Airtac SGC Standard Cylinder SGC125X70SN is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 70mm 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 SGC125X70SN
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is built for large-bore automation tasks. Four steel tie rods clamp the aluminium barrel to the covers for high structural rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life. The -S suffix equips the piston with a magnet for CMSG, DMSG, or EMSG switches, and the -N designation specifies NBR seals for specific media compatibility.
Because it uses the standardized ISO 15552 mounting interface, this model drops directly into existing large-bore fixtures without custom brackets. Plan for about 3682 N of real work at 0.5 MPa, which translates to lifting roughly 313 kg vertically with a 2:1 safety margin. The G1/2 air port and M27x2.0 rod thread ensure straightforward plumbing and mechanical integration.

Where the Airtac SGC Standard Cylinder SGC125X70SN Is Used
Press Fit Assembly
Drives bearings into automotive housings with 6136 N of push force, using the integrated magnet for precise stroke-end confirmation.
Pallet Stopper Gate
Acts as a heavy-duty pneumatic stop on high-throughput packaging conveyors, holding back loaded pallets weighing up to 313 kg.
Plastic Mold Ejection
Ejects large injection-molded plastic panels from heavy tooling, relying on the rigid tie-rod construction to absorb impact without deflection.
Is the Airtac SGC Standard Cylinder SGC125X70SN the Right Cylinder?
When sizing this 125 mm bore unit, consider the adjacent SGC options: the SGC160 offers substantially more thrust with 10053 N push at 0.5 MPa, while there is no smaller SGC bore below 125. If your application strictly requires holding a load vertically during air loss or valve centering, note that the adjustable air cushion only decelerates the piston near stroke end and does not act as a brake; an external rod lock or pilot-operated check valve is required for secure positioning. The 70 mm stroke keeps the rod compact, minimizing side-load bending moments, but always ensure rigid guidance on the tooling plate. The NBR seals suit general industrial environments, and the integrated magnet allows precise end-of-stroke detection.
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 SGC125X70SN 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 force of 1251 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so it drops into standard large-bore fixtures. The -S suffix means it has a built-in piston magnet ready for CMSG, DMSG, or EMSG switches, and the -N indicates NBR seals.
