Airtac SGCD Dual Rod Cylinder SGCD250X80
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X80 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 80mm stroke, G1 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 SGCD250X80
Delivering 23562 N of equal thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder features a piston rod exiting both covers. Because both faces use the identical rod-side area, push and pull forces remain perfectly matched at 32986 N at 0.7 MPa. The four steel tie rods clamp the aluminum barrel securely, while the G1 air port feeds the 250 mm bore. A standard 80 mm stroke keeps the assembly compact.
This symmetric load path prevents piston rotation, making the unit ideal for guiding heavy platens or driving twin tool stations simultaneously. It yields a safe working load of roughly 14137 N, capable of vertically lifting about 1201 kg with a 2:1 margin. Note that this 250 mm bore skips TPU seals entirely, utilizing NBR packings instead, with a Viton H option available for 0-150 C environments. As a non-magnetized SKU, it cannot accept position sensors.

Theoretical Output Force (Ø250mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 23562 N | 23562 N |
| 0.7 MPa | 32987 N | 32987 N |
| Max (@1.0 MPa) | 5006 kgf | |
Double-rod: the rod passes through both covers, so output force is equal in both directions.

Where the Airtac SGCD Dual Rod Cylinder SGCD250X80 Is Used
Twin-Tool Punching
Drives two matched stamping tools simultaneously from opposite rod ends, ensuring perfectly synchronized cutting cycles.
Symmetric Platen Lift
Lifts heavy machining platens with equal force both ways, preventing mechanical twist during vertical actuation.
Dual-Side Diverting
Actuates opposing diverting arms on a wide conveyor line from a single centralized ISO 15552 mounting point.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X80 the Right Cylinder?
Sizing this double-rod unit means balancing against adjacent bores: the 200 mm delivers 15079 N both ways at 0.5 MPa, while the 250 mm sits at the top edge with 23562 N. Choose the double-rod configuration when your mechanism demands anti-rotation guidance, twin tooling driven from one piston, or a symmetric load path. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because this specific SKU lacks the -S magnet, it cannot host CMSG, DMSG, or EMSG sensors; add the -S variant if you require position detection. Even at 80 mm stroke, always support external side loads with a separate guide rail 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 SGCD250X80 FAQ
The 250 mm bore generates equal force both ways: 23562 N at 0.5 MPa and 32986 N at 0.7 MPa, with a theoretical max of 4805 kgf at 1.0 MPa. It features a G1 port, M42x2.0 rod thread, and 60 mm adjustable air cushions at both ends.
No, the air cushions only decelerate the piston near stroke end and do not act as a brake. If power fails, the load will drift; you must use an external rod lock or pilot-operated check valve for secure load holding.
