Airtac SGCD Dual Rod Cylinder SGCD250X900
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X900 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 900mm 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 SGCD250X900
Delivering 23562 N of thrust in both directions at 0.5 MPa, this large-bore double-rod cylinder uses a single Ø50 mm piston rod exiting both covers to equalize the pressure area. The twin-rod layout prevents piston rotation, enabling precise non-twist guidance for heavy loads, while the symmetric load path balances stress across the four steel tie rods that clamp the aluminum barrel.
Built to the ISO 15552 mounting interface, it drops directly into standard large-bore fixtures and uses a G1 air port. Because this is a 900 mm stroke, you must add external guides to prevent rod bending under side loads. It yields a safe working load of about 14137 N, capable of vertically lifting roughly 1201 kg with a 2:1 safety margin. Note that TPU seals are unavailable on this bore; it uses NBR packing, 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 SGCD250X900 Is Used
Twin-Press Stamping
Drives two synchronized forming tools from opposite rod ends, utilizing the equal 32986 N force at 0.7 MPa to stamp heavy-gauge metal without rotational drift.
Balanced Platen Lowering
Lowers heavy machinery platens symmetrically using both rod ends, keeping the load perfectly level across the 900 mm travel without twisting.
Dual-End Diverting
Actuates opposing diverters on a high-capacity conveyor simultaneously, using the through-rod design to push and pull routing gates from a single central mount.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X900 the Right Cylinder?
Sitting at the top of the SGCD range, this 250 mm bore outputs 23562 N each way at 0.5 MPa. If your application needs less force, step down to the 200 mm bore which provides 15079 N both ways. You only need this model for heavy-duty pushing and pulling that exceeds smaller bores. A double-rod design is the right call when you require anti-rotation stability, need to drive twin tooling simultaneously from one piston, or want a symmetric load path. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. Finally, for this 900 mm stroke, external rod-end support is mandatory to handle side loads and prevent rod bending.
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 SGCD250X900 FAQ
Because it is a double-rod cylinder, force is equal in both directions using the pull-side area. It delivers 23562 N at 0.5 MPa and 32986 N at 0.7 MPa. The theoretical maximum force is 4805 kgf at 1.0 MPa. It features a G1 air port and an M42x2.0 rod-end thread.
No, a plain SGCD cylinder drifts without live air and the air cushion only decelerates near the stroke end; use an external rod lock or pilot-operated check valve for load holding. Additionally, this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.
