Airtac SGC Standard Cylinder SGC125X900SH
The AirTAC Airtac SGC Standard Cylinder SGC125X900SH is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 900mm 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 SGC125X900SH
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles heavy-duty automation with ease. Four steel tie rods clamp the aluminum barrel to the covers, providing the high rigidity needed for large-bore thrust, while a two-way piston seal maintains an internal oil reservoir for prolonged lubrication. Plan for about 3682 N of real work at 0.5 MPa, which translates to lifting roughly 313 kg vertically with a 2:1 safety margin.
The built-in piston magnet (-S) supports CMSG, DMSG, and EMSG switches for precise end-position detection. Configured with Viton H seals (-H), the unit operates reliably from 0 to 150 C, making it suitable for heated environments. It features a 32 mm rod, an M27x2.0 rod thread, and a G1/2 port.

Where the Airtac SGC Standard Cylinder SGC125X900SH Is Used
Injection Mold Platen Ejection
Provides the 6136 N push force required to eject heavy plastic parts from molds, with Viton H seals enduring ambient heat radiating from the press.
High-Reach Pallet Dispenser
Utilizes its 900 mm stroke to push empty pallets into elevated stacking cradles, where the ISO 15552 mounting interface simplifies fixture integration.
Hot-End Material Transfer
Shifts heavy cast components out of ovens, relying on the 0 to 150 C Viton temperature rating to maintain seal integrity near radiant heat.
Is the Airtac SGC Standard Cylinder SGC125X900SH the Right Cylinder?
When sizing this 125 mm bore unit, verify if the 6136 N push at 0.5 MPa meets your target, keeping in mind it is the smallest SGC option with no smaller bore available. If your application requires substantially more power, stepping up to the 160 mm bore yields 10053 N at 0.5 MPa. Because this model has a 900 mm stroke, external guides are strongly recommended to prevent rod bending and absorb side loads during long extensions. The adjustable 40 mm air cushions decelerate the piston near stroke ends but do not function as a brake; for load holding on air loss, install an external rod lock or 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 SGC125X900SH FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it provides 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa. This 125 mm bore cylinder uses a G1/2 air port.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so it drops directly into existing large-bore fixtures. You can pair it with LB foot mounts, FA flanges, or TC trunnions, and the -S magnet enables CMSG, DMSG, and EMSG sensors.
