Airtac SGC Standard Cylinder SGC125X140TC
The AirTAC Airtac SGC Standard Cylinder SGC125X140TC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 140mm 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 SGC125X140TC
Delivering 6136 N of push force at 0.5 MPa, this double-acting 125 mm bore tie-rod cylinder is built for heavy-duty automation. The 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. Plan for about 3682 N of real work at 0.5 MPa, which lifts roughly 313 kg vertically with a 2:1 safety margin.
Because it uses the standardized ISO 15552 mounting interface, it drops directly into existing large-bore fixtures and accessory sets. This specific SKU features a TC trunnion mount and a 140 mm stroke, but lacks a magnet. Consequently, it cannot accept CMSG, DMSG, or EMSG position switches without upgrading to the -S variant. The bore dictates a G1/2 air port and an M27x2.0 rod thread.

Where the Airtac SGC Standard Cylinder SGC125X140TC Is Used
Pallet Diverting
Actuates heavy pallet lane diverters on high-throughput packaging lines, utilizing the 6136 N thrust to push loaded pallets smoothly.
Press Ejection
Ejects formed metal parts from stamping presses, where the TC trunnion mount accommodates the angular shifts during the 140 mm ejection stroke.
Material Handling
Indexes heavy workpieces onto machining centers, using the ISO 15552 interface to swap directly into existing tooling cradles.
Is the Airtac SGC Standard Cylinder SGC125X140TC the Right Cylinder?
When sizing this 125 mm bore option, verify if the 6136 N push at 0.5 MPa provides adequate thrust. Stepping up to the 160 mm bore yields 10053 N, while there is no smaller SGC bore below 125. For position feedback, note this non-magnetic SKU cannot host a sensor; you must specify the -S option to use CMSG or DMSG switches.
At 140 mm stroke, side-load risks are minimal, but always ensure the TC trunnion mounting aligns with the load trajectory. Remember that a standard cylinder drifts when air is lost or the valve is centered, as the air cushion only decelerates the piston near stroke end. To suspend a load safely, install an external rod lock or a pilot-operated check valve.
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 SGC125X140TC FAQ
The 125 mm bore provides 6136 N push and 5734 N pull at 0.5 MPa, increasing to 8590 N push and 8028 N pull at 0.7 MPa, with a theoretical maximum of 1251 kgf at 1.0 MPa. The air port size is G1/2.
No, this specific SKU lacks a piston magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must select the -S magnet variant for position sensing capabilities.
