About the Airtac SGC Standard Cylinder SGC125X170
Delivering 6136 N of push force at 0.5 MPa, this double-acting tie-rod cylinder brings large-bore power to automated lines. It features a 125 mm bore, a 170 mm stroke, and a G1/2 air port. Four steel tie rods clamp the aluminium barrel to the covers for high rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life.
Because this specific SKU lacks the -S magnet, it cannot host CMSG, DMSG, or EMSG sensors. It uses a TPU seal rated for -20 to +70 C, with Viton H available for 0-150 C environments. Dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures.

Where the Airtac SGC Standard Cylinder SGC125X170 Is Used
Press Fit Assembly
Drives bearings into heavy housings on automotive production lines using its 8590 N push force at 0.7 MPa.
Pallet Stopping Gate
Acts as a robust pneumatic stop gate for heavy unit loads on conveyor transfers, absorbing impact via its tie-rod build.
Plastic Mould Ejection
Provides the secondary ejection stroke for large injection moulding machines, utilizing its 170 mm travel.
Is the Airtac SGC Standard Cylinder SGC125X170 the Right Cylinder?
This 125 mm bore sits at the entry point of the SGC large-bore family. If your application requires less force, you must step outside the SGC range, as there is no smaller bore in this series. If you need more thrust, the 160 mm bore provides 10053 N at 0.5 MPa. The 170 mm stroke is well under the 1500 mm maximum, so side-load concerns are minimal, but always ensure axial alignment to prevent rod bending.
Remember that a standard cylinder drifts when air is lost or the valve is centered; the adjustable 40 mm air cushions only decelerate the piston near stroke ends, acting neither as a lock nor a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve. For position feedback, select the -S magnet variant to enable sensing switches.
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 SGC125X170 FAQ
The 125 mm bore features a G1/2 port and a 32 mm rod. 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, this specific SKU does not include a magnet. You must select the -S variant to mount CMSG, DMSG, or EMSG switches. The unit is dimensionally interchangeable per the ISO 15552 mounting interface.
