Airtac SGC Standard Cylinder SGC125X500H
The AirTAC Airtac SGC Standard Cylinder SGC125X500H is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 500mm 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 SGC125X500H
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder handles heavy duty cycles in extreme environments. The SGC125X500H features a high-temperature Viton seal option, extending the operating range from -20 to +150 C. 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.
Because this SKU lacks the -S magnet, it cannot accept 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 G1/2 port and M27x2.0 rod thread match the standard 125 mm bore specification.

Where the Airtac SGC Standard Cylinder SGC125X500H Is Used
Hot Stamp Press Ejection
Ejects heavy molded parts from a hot stamping press, utilizing the Viton seal to withstand ambient radiant heat up to 150 C while pushing with 6136 N.
Long-Reach Part Transfer
Transfers automotive components across a 500 mm gap between machining centers, requiring external guide rails to maintain alignment under the 313 kg safe vertical lift capacity.
High-Temp Pallet Stopper
Acts as a heavy-duty stopping mechanism on a heat-treat line conveyor, where the ISO 15552 mounting interface allows easy fixture integration and the tie-rod build resists impact.
Is the Airtac SGC Standard Cylinder SGC125X500H the Right Cylinder?
This 125 mm bore sits at the entry point of the SGC large-bore family, offering 6136 N push at 0.5 MPa. If your application requires less force, there is no smaller SGC model, so you would need to look outside this series. If you need more power, stepping up to the 160 mm bore yields 10053 N of push force at the same pressure. Since this is a 500 mm stroke, add external guide rails to prevent rod bending and side-load damage during long extensions.
The standard air cushion only decelerates the piston near the stroke end and does not function as a brake. If air pressure drops or the valve is centered, the load will drift, so install an external rod lock or pilot-operated check valve for secure vertical holding.
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 SGC125X500H FAQ
The 125 mm bore provides 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 and an M27x2.0 rod thread.
This specific SKU does not include a magnet, so it cannot support CMSG, DMSG, or EMSG switches without upgrading to an -S variant. However, it includes the Viton H seal, raising the operating temperature range to 0-150 C instead of the standard -20 to +70 C.
