Airtac SGC Standard Cylinder SGC125X650S
The AirTAC Airtac SGC Standard Cylinder SGC125X650S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 650mm 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 SGC125X650S
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is built for large-bore automation tasks. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, while the two-way piston seal maintains an internal oil reservoir to maximize service life. The G1/2 port and M27x2.0 rod thread streamline integration into existing pneumatic setups.
Because this SKU includes the -S magnet, it directly supports CMSG, DMSG, and EMSG position switches for end-of-stroke detection. Plan for roughly 3682 N of real work at 0.5 MPa, which translates to lifting about 313 kg vertically with a 2:1 safety margin. The standard TPU seals handle temperatures from -20 to +70 C, though a Viton H option extends this range up to 150 C for heated environments.

Where the Airtac SGC Standard Cylinder SGC125X650S Is Used
Pallet Diversion Gate
Actuates heavy diverter arms on high-throughput packaging conveyors, using the 650 mm stroke to fully clear the pallet path before retraction.
Automated Storage Retrieval
Provides the horizontal extraction force to pull standardized totes from dense shelving units, relying on the -S magnet to confirm tote engagement.
Injection Mold Ejection
Drives long-stroke ejector pins on large injection molding machines, pushing heavy cured parts clear of the tooling cavity.
Is the Airtac SGC Standard Cylinder SGC125X650S the Right Cylinder?
When sizing this 125 mm bore against the SGC family, it sits at the entry point of the large-bore range—there is no smaller SGC bore, but stepping up to the 160 mm bore increases push force to 10053 N at 0.5 MPa if your application demands more authority. For the 650 mm stroke specifically, the extended rod length makes it highly susceptible to side-load damage and bending; always use an external guide or stopper to prevent rod deflection under load. Furthermore, a standard cylinder drifts when air is lost or the valve is centered—the adjustable air cushion only decelerates the piston near the end caps and acts purely as a shock absorber, never as a locking device. To suspend a load safely mid-stroke, incorporate an external rod lock or a pilot-operated check valve into your circuit.
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 SGC125X650S FAQ
This 125 mm bore cylinder features a G1/2 air port and an M27x2.0 rod thread. The thrust output is 6136 N push and 5734 N pull at 0.5 MPa, increasing to 8590 N push and 8028 N pull at 0.7 MPa. The theoretical maximum force is 1251 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, meaning it drops directly into standard large-bore foot, flange, and trunnion fixtures. Because this SKU has the -S magnet, it readily accepts CMSG, DMSG, and EMSG electronic or reed switches for position sensing.
