Airtac SGCD Dual Rod Cylinder SGCD250X500
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X500 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 500mm 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 SGCD250X500
Delivering 23562 N of thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod piston to balance loads perfectly. The symmetric design prevents torsional twist, letting you drive two tools at once or mount a rear sensor cam. With a 60 mm adjustable air cushion at each end and a G1 port, it handles rapid 30-500 mm/s cycles smoothly.
Because the rod passes through both covers, the effective area matches on both faces, yielding a theoretical maximum of 4805 kgf at 1.0 MPa. This translates to a safe working load of about 14137 N, or roughly 1201 kg lifted vertically with a 2:1 safety margin. Note that TPU seals are unavailable for this 250 mm bore; it uses NBR packings, with a Viton H option for 0-150 C heat.

Theoretical Output Force (Ø250mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 23562 N | 23562 N |
| 0.7 MPa | 32987 N | 32987 N |

Where the Airtac SGCD Dual Rod Cylinder SGCD250X500 Is Used
Heavy Pallet Lifting
Equal push and pull thrust of 23562 N at 0.5 MPa keeps massive pallet elevators balanced without drifting or twisting during vertical transit.
Dual Transfer Arms
Drive two opposing transfer arms simultaneously using the protruding rod at each end, ensuring perfectly synchronized part handoff across the line.
Press Ejection Systems
The symmetric load path and 60 mm adjustable cushions absorb heavy end-of-stroke impacts on large stamping presses, safely decelerating heavy molds.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X500 the Right Cylinder?
As the largest bore in the series, this 250 mm model sits at the top edge, stepping up from the 200 mm version which provides 15079 N both ways at 0.5 MPa. Choose a double-rod configuration when your mechanism demands anti-rotation stability, symmetric load paths, or twin tooling driven from one piston. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Since this is a non-magnetized SKU, it cannot accept CMSG/DMSG/EMSG sensors; specify the -S variant if you need position detection. For this 500 mm stroke, always use external guides to prevent rod bending under heavy side loads.
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 SGCD250X500 FAQ
Force is equal in both directions due to the double-rod design: 23562 N at 0.5 MPa, 32986 N at 0.7 MPa, and a theoretical max of 4805 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a 1.5 MPa proof pressure.
No, the air cushion only decelerates the piston; it will drift if air is lost. Use an external rod lock or pilot-operated check valve for load holding. Additionally, this non-S SKU lacks a magnet and cannot take sensors; you need the -S version for CMSG/DMSG/EMSG switches.
