Airtac SGCD Dual Rod Cylinder SGCD125X200S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X200S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 200mm 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 SGCD125X200S
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 output force. The G1/2 port feeds a 125 mm bore that safely handles about 3440 N of real work, translating to a 292 kg vertical lift with a 2:1 margin.
Four steel tie rods clamp the aluminum barrel for high rigidity, while the symmetric load path prevents torsional twist. Because the -S suffix includes a piston magnet, you can mount CMSG, DMSG, or EMSG sensors directly for end-of-stroke detection.

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 SGCD125X200S Is Used
Twin-Spindle Machining
Drives two opposing machining heads simultaneously from one piston, ensuring perfectly synchronized parting cuts.
Symmetric Transfer Pusher
Pushes a workpiece forward while the rear rod retracts a diverter cam, maintaining a balanced load path.
Anti-Rotation Lift Station
Lifts a 292 kg platen vertically without twisting, using the dual rods as integral anti-rotation guides.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X200S the Right Cylinder?
Size both ways: the smaller 125 mm bore yields 5734 N each way at 0.5 MPa, whereas stepping up to the 160 mm bore provides 9425 N. Choose this double-rod configuration when you need anti-rotation guidance, twin tooling driven from one piston, or a rear rod acting as a sensor cam. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The built-in magnet supports reed and electronic switches. For any stroke exceeding 500 mm, always use external guide rails to prevent side-load 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 SGCD125X200S FAQ
Force is equal in both directions at 5734 N at 0.5 MPa and 8028 N at 0.7 MPa. The theoretical maximum is 1169 kgf at 1.0 MPa. It operates from 0.15 to 1.0 MPa and features a G1/2 port.
No, the adjustable 40 mm air cushions only decelerate the piston near the end caps. To prevent drift on air loss, install an external rod lock or a pilot-operated check valve.
