Airtac SGCD Dual Rod Cylinder SGCD125X125
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X125 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 125mm 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 SGCD125X125
Delivering 5734 N of thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod piston to equalize force. It yields a safe working load of about 3440 N, which is roughly 292 kg lifted vertically with a 2:1 margin. The G1/2 port feeds the 125 mm bore, operating at 30-500 mm/s.
Four steel tie rods clamp the aluminum barrel for high rigidity, while the symmetric load path prevents piston twisting. This non-magnetic SKU cannot take a sensor; adding the -S variant enables CMSG/DMSG/EMSG switches. The standard TPU seals handle -20 to +70 C, with a Viton H option for 0-150 C heat.

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 SGCD125X125 Is Used
Twin-Spindle Machining
Drives two opposing machining heads simultaneously using the symmetric rod extension on both covers.
Anti-Rotation Transfer
Moves pallets along a conveyor without twisting, relying on the double-rod piston for geometric stability.
Balanced Vertical Lift
Raises and lowers a 292 kg platen with equal push and pull force, maintaining smooth deceleration via the 40 mm cushions.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X125 the Right Cylinder?
This 125 mm bore sits at the low edge of the SGCD range; step up to the 160 mm bore for 9425 N if you need more power, or down to the smaller SGC single-rod family if equal two-way force is unnecessary. Choose a double-rod design when you need anti-rotation guidance, twin tooling driven from both ends, or a symmetric load path. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because this stroke is 125 mm, side-load is minimal, but any stroke over 500 mm requires external guide rails to prevent rod binding.
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 SGCD125X125 FAQ
Because the rod passes through both covers, force is equal in both directions: 5734 N at 0.5 MPa, 8028 N at 0.7 MPa, and a theoretical max of 1169 kgf at 1.0 MPa. The G1/2 port supplies the 125 mm bore.
No. A plain SGCD cylinder drifts on air loss, as the adjustable air cushion only decelerates near stroke end. For a held load, install an external rod lock or a pilot-operated check valve.
