Airtac SGC Standard Cylinder SGC125X125TC
The AirTAC Airtac SGC Standard Cylinder SGC125X125TC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 125mm 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 SGC125X125TC
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore ISO 15552 tie-rod cylinder is built for rigorous automation. 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. The G1/2 port and M27x2.0 rod thread handle the demanding air flow required for the 125 mm bore.
Because this specific SKU lacks the -S magnet, it cannot host CMSG, DMSG, or EMSG position switches. For practical sizing, plan for about 3682 N of real work at 0.5 MPa, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin. The standardized ISO 15552 mounting interface means it drops directly into existing large-bore fixtures, and the included TC trunnion mount simplifies pivoting load integration.

Where the Airtac SGC Standard Cylinder SGC125X125TC Is Used
Press Fit Assembly
Drives bearings into heavy housings on an automotive line, utilizing the 6136 N push force to seat components reliably.
Pallet Diverter
Actuates a heavy-duty diverter arm on a packaging conveyor, pivoting smoothly via the TC trunnion mount to redirect large pallets.
Material Lift Gate
Raises and lowers a loaded transfer gate in a distribution hub, handling the 313 kg vertical lift capacity with a safe 2:1 margin.
Is the Airtac SGC Standard Cylinder SGC125X125TC the Right Cylinder?
When sizing this 125 mm bore unit, verify if the 6136 N push at 0.5 MPa provides adequate thrust; if your application requires less force, stepping down requires leaving the SGC family, while stepping up to the 160 mm bore yields 10053 N. This model uses a TC trunnion setup, so ensure your frame supports the pivot loads. Remember that a standard cylinder drifts when air is lost or the valve is centered—the adjustable air cushion only decelerates the piston near stroke end, so install an external rod lock or pilot-operated check valve if the load must be held. At 125 mm stroke, side-load risks are minimal, but always guide the rod end to prevent binding.
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 SGC125X125TC FAQ
This 125 mm bore cylinder features a G1/2 air port and delivers 6136 N push / 5734 N pull at 0.5 MPa, 8590 N push / 8028 N pull at 0.7 MPa, with a theoretical maximum force of 1251 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet, so it cannot support CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing.
