Airtac SGCD Dual Rod Cylinder SGCD125X75
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X75 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 75mm 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 SGCD Dual Rod Cylinder SGCD125X75
Delivering 5734 N of thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder features a piston rod exiting both covers for perfectly symmetric operation. Because the pressure area is identical on each face, you get the exact same push and pull force, making it ideal for about 3440 N of real work or roughly 292 kg of vertical lift with a 2:1 safety margin. The G1/2 port feeds the 125 mm bore, while four steel tie rods clamp the aluminum barrel securely to the covers for high structural rigidity.
A rod extending from the back end provides a natural anti-rotation effect and can drive a secondary tool or carry a sensor cam without extra engineering. This non-magnetic SKU cannot accept position switches; you must specify the -S variant to use CMSG, DMSG, or EMSG sensors. Note that the adjustable 40 mm air cushions only decelerate the piston near stroke end—a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended load.

Theoretical Output Force (Ø125mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 5734 N | 5734 N |
| 0.7 MPa | 8027 N | 8027 N |
| Max (@1.0 MPa) | 1251 kgf | |
Double-rod: the rod passes through both covers, so output force is equal in both directions.

Where the Airtac SGCD Dual Rod Cylinder SGCD125X75 Is Used
Twin-Tool Machining Station
Drives two opposing machining heads simultaneously using the front and rear rod ends, ensuring perfectly synchronized part processing.
Symmetric Lift Platform
Lifts and lowers a balanced platen with equal force both ways, preventing sagging and maintaining precise vertical alignment.
Anti-Twist Divert Gate
Shifts a heavy diverting gate on a high-speed line where a single rod might twist under offset load, keeping the gate tracking straight.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X75 the Right Cylinder?
Sizing this actuator involves looking at both neighbours: the SGCD160 offers 9425 N each way at 0.5 MPa, while there is no smaller SGCD bore, making 125 mm the low edge of this large-frame family. Choose the double-rod configuration when your mechanism requires anti-rotation guidance, twin tooling on one carrier, a symmetric load path, or a rear-end sensor cam. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. For any stroke at or above 500 mm, support the rod externally to prevent side-load wear. This 75 mm stroke version lacks the -S magnet, so it cannot host CMSG/DMSG/EMSG switches.
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 SGCD Dual Rod Cylinder SGCD125X75 FAQ
Because it is a double-rod design, the force is equal in both directions using the rod-side area. It generates 5734 N at 0.5 MPa and 8028 N at 0.7 MPa. The theoretical maximum pull force is 1169 kgf at 1.0 MPa. The bore uses a G1/2 air port.
No, this specific SKU does not include a magnet. To use CMSG, DMSG, or EMSG magnetic switches, you must purchase the -S variant of the SGCD125. The double-rod design does, however, allow you to mount a mechanical cam on the rear rod for external sensing.
