Airtac SGC Standard Cylinder SGC125X100H
The AirTAC Airtac SGC Standard Cylinder SGC125X100H is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 100mm 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 SGC125X100H
Delivering 6136 N of push force at 0.5 MPa, this large-bore tie-rod actuator is built for demanding thermal environments. The SGC125X100H is a double-acting ISO 15552 cylinder featuring a 125 mm bore, 100 mm stroke, and a Viton H seal that extends the operating temperature range up to 150 C. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, while the G1/2 port supplies air to the 32 mm chrome-plated rod. A heterogeneous two-way piston seal maintains an internal oil reservoir to maximize operational lifespan.
Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches. For actual work output at 0.5 MPa, plan for about 3682 N of real load, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin. The adjustable 40 mm air cushions at both ends absorb kinetic energy near the stroke limits, but they act only as decelerators, not as braking locks.

Where the Airtac SGC Standard Cylinder SGC125X100H Is Used
Injection Mold Clamping
Secures heavy mold halves inside hot manufacturing cells where the Viton H seal survives ambient temperatures up to 150 C without degrading.
Automotive Press Ejection
Pushes stamped metal parts out of hydraulic presses using 6136 N of force at 0.5 MPa, relying on the 40 mm adjustable cushion to stop the stroke smoothly.
Heavy Pallet Diversion
Extends 100 mm to knock oversized industrial pallets off a main conveyor line, utilizing the rigid four-tie-rod construction to handle repeated side impacts.
Is the Airtac SGC Standard Cylinder SGC125X100H the Right Cylinder?
Choosing this 125 mm bore makes sense when you need approximately 3682 N of usable thrust at 0.5 MPa. If your application requires less force, there is no smaller SGC bore available, 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 at 0.5 MPa. To mount this unit, utilize the standardized ISO 15552 interface with LB foot brackets, FA flanges, or TC trunnions.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centered, so install an external pilot-operated check valve if the load must be held in place. Since this 100 mm stroke is relatively short, side-load stress on the rod is minimal. If your design later requires a stroke of 500 mm or more, add external guide rails to prevent rod bending. Finally, if your machine needs position feedback, select the -S magnet variant instead of this SKU, as it cannot host a reed or solid-state sensor.
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 SGC125X100H FAQ
At 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. At 0.7 MPa, push is 8590 N and pull is 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, and the Viton H seal allows a temperature range of 0-150 C.
No, this specific SKU does not include the -S magnet option, so it cannot host CMSG, DMSG, or EMSG switches. You would need to order the -S variant for magnetic sensing. However, it retains the ISO 15552 mounting interface, ensuring full dimensional interchangeability with standard large-bore fixtures and accessories.
