Airtac SGC Standard Cylinder SGC125X400
The AirTAC Airtac SGC Standard Cylinder SGC125X400 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 400mm 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 SGC125X400
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder handles substantial work. Its four steel tie rods clamp the aluminum barrel to the covers, providing the high rigidity needed for heavy thrust. The two-way piston seal retains an oil reservoir for long service life. Plan for about 3682 N of real work at 0.5 MPa, or roughly 313 kg lifted vertically with a 2:1 margin.
Built to the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures. This SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG switches. It features a 32 mm rod, a G1/2 port, and an M27x2.0 rod thread. The 40 mm adjustable air cushions at both ends absorb end-of-stroke impact.

Where the Airtac SGC Standard Cylinder SGC125X400 Is Used
Pallet Diversion
Pushes heavy wood or steel pallets sideways off a high-speed main conveyor line using its 6136 N thrust capacity.
Heavy Gate Operation
Actuates large automated warehouse security gates or blast doors, utilizing the 400 mm stroke to clear the opening.
Press Ejection
Ejects dense stamped metal parts from a hydraulic press bed, relying on the rigid tie-rod build to withstand shock loads.
Is the Airtac SGC Standard Cylinder SGC125X400 the Right Cylinder?
When sizing, the 125 mm bore is the smallest in the SGC family, offering 6136 N push at 0.5 MPa. If your application requires more power, stepping up to the 160 mm bore provides 10053 N of push force at the same pressure. Because this 400 mm stroke is relatively long, ensure external guide rails are used to prevent rod bending and side-load damage.
Note 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 hold a load securely, 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 SGC125X400 FAQ
The SGC125X400 delivers a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, push is 8590 N and pull is 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa. It uses a G1/2 air port.
No, this specific SKU does not include a magnet. To use CMSG, DMSG or EMSG magnetic switches, you must select the SGC125X400-S variant. The ISO 15552 mounting interface ensures it shares dimensions with standard large-bore fixtures.
