Airtac SGC Standard Cylinder SGC125X1000H
The AirTAC Airtac SGC Standard Cylinder SGC125X1000H is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1000mm 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 SGC125X1000H
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder integrates a high-temperature Viton H seal rated for 0 to 150 C. The SGC125X1000H utilizes a robust tie-rod construction where four steel rods clamp the aluminum barrel to the covers, ensuring high rigidity under heavy thrust. Its two-way piston seal maintains an internal oil reservoir for sustained lubrication and long service life.
Because it follows the standardized ISO 15552 mounting interface, this model drops directly into existing large-bore fixtures and shares common accessory dimensions. Equipped with a G1/2 port and a 1000 mm stroke, it provides 8590 N of thrust at 0.7 MPa. Plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin.

Where the Airtac SGC Standard Cylinder SGC125X1000H Is Used
Injection Mold Platen Ejection
Drives heavy mold ejection plates in high-temperature cell environments, utilizing the Viton H seal to withstand ambient heat near the barrel while delivering 6136 N of push at 0.5 MPa.
Automotive Press Transfer
Moves large stamped body panels across a 1000 mm gap, relying on ISO 15552 mounting dimensions for rigid fixture integration and external guides to prevent rod bending.
Hot Product Diversion
Actuates heavy diverter arms on conveyor lines handling freshly cooled cast components, where the 0.15-1.0 MPa operating pressure and TPU/Viton options provide flexible deployment.
Is the Airtac SGC Standard Cylinder SGC125X1000H the Right Cylinder?
When sizing this 125 mm bore, stepping down is not an option within the SGC family, but stepping up to the 160 mm bore yields 10053 N of push at 0.5 MPa for heavier demands. This specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG magnetic switches; order the -S variant if position sensing is required. The Viton H seal makes it ideal for hot environments up to 150 C.
At a 1000 mm stroke, the 32 mm rod is highly susceptible to bending under side loads, so external guide rails and rigid rod-end support are mandatory. Note that a standard cylinder drifts when air is lost or the valve is centered, as the adjustable air cushion only decelerates the piston near stroke end rather than locking it; install an external rod lock or pilot-operated check valve to hold suspended loads safely.
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 SGC125X1000H FAQ
This 125 mm bore cylinder features a G1/2 port and generates 6136 N push / 5734 N pull at 0.5 MPa, 8590 N push / 8028 N pull at 0.7 MPa, and a theoretical maximum of 1251 kgf at 1.0 MPa. It operates at speeds of 30-500 mm/s.
The SGC125X1000H includes the Viton H seal for 0 to 150 C high-temperature environments, but it lacks the -S magnet, so CMSG, DMSG, or EMSG switches cannot be fitted. The four steel tie rods clamp the assembly to ISO 15552 mounting interface dimensions for direct fixture interchangeability.
