Airtac SGC Standard Cylinder SGC125X180TC
The AirTAC Airtac SGC Standard Cylinder SGC125X180TC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 180mm 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 SGC125X180TC
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles heavy-duty positioning with ease. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, while the two-way piston seal maintains an internal oil reservoir to maximize service life. Because it is dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures.
This 125 mm bore variant uses a G1/2 air port and a 32 mm hard-chrome rod, traveling 180 mm at speeds between 30 and 500 mm/s. Plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin. 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 SGC125X180TC Is Used
Press Ejection
Provides the robust 6136 N stroke needed to knock heavy stamped parts out of a hydraulic press bed.
Pallet Diverting
Swings a TC-mounted diverter arm to reroute loaded pallets between adjacent roller conveyor lines.
Lift Gate Actuation
Raises and lowers heavy loading dock gates, relying on the 180 mm stroke to clear the dock lip.
Is the Airtac SGC Standard Cylinder SGC125X180TC the Right Cylinder?
When sizing this unit, compare its 6136 N push force at 0.5 MPa against the next size up: the 160 mm bore provides 10053 N if your application demands more thrust, while the 125 mm remains the entry point for the SGC large-bore range. The integrated TC trunnion mount is ideal for pivoting loads, but keep in mind that a plain cylinder drifts when air is lost or the valve is centered. The adjustable air cushion only decelerates the piston near the stroke ends, so add an external rod lock or pilot-operated check valve if you need to hold a suspended load.
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 SGC125X180TC 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 of 1251 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet, so it cannot host CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing capabilities.
