Airtac SGCD Dual Rod Cylinder SGCD250X450
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X450 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 450mm 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 SGCD250X450
Delivering 23562 N of thrust in both directions at 0.5 MPa, this large-bore double-rod cylinder is built for heavy-duty symmetric motion. A piston rod exits both the front and rear covers, meaning the effective pressure area is identical on the extend and retract strokes. This equal-both-ways output makes it good for about 14137 N of real work, roughly 1201 kg lifted vertically with a 2:1 safety margin. The G1 air port handles the high volume needed for rapid cycling.
Four steel tie rods clamp the aluminum barrel to the covers, providing structural rigidity under high loads, while the genuine ISO 15552 mounting interface ensures dimensional interchangeability with standard large-bore fixtures. Because this is a 250 mm bore, TPU seals are not available; instead it uses NBR packings, with a Viton H option for 0-150 C high-heat environments. Note this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG magnetic switches.

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 SGCD250X450 Is Used
Twin-Spindle Press
Drives two opposing forming tools simultaneously using the protruding rod at each end, ensuring perfectly balanced pressing force up to 23562 N at 0.5 MPa.
Symmetric Lift Platform
Lifts heavy platens evenly from both ends to prevent twisting under load, utilizing the equal push and pull areas to maintain precise vertical alignment.
Dual-End Transfer
Indexes heavy pallets on a 450 mm cycle using one rod to push and the opposite rod to simultaneously retract a return linkage, keeping the motion path stable.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X450 the Right Cylinder?
Sizing this actuator involves comparing adjacent bores: the 200 mm version provides 15079 N each way 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 stability, needs to drive two tools simultaneously from one piston, or requires a symmetric load path. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets. At a 450 mm stroke, you must support any side loads with external guide rails to prevent binding and premature seal wear. Finally, remember this non-magnetic SKU cannot host position sensors; you need the -S variant for CMSG/DMSG/EMSG switches.
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 SGCD250X450 FAQ
The force is equal in both directions because the rod passes through both covers. It generates 23562 N at 0.5 MPa and 32986 N at 0.7 MPa each way, with a theoretical max of 4805 kgf at 1.0 MPa. It features a 250 mm bore, 450 mm stroke, G1 port, M42x2.0 rod thread, and 60 mm adjustable air cushions.
No, a plain cylinder drifts on air loss and the cushions only decelerate near stroke end; use an external rod lock or pilot-operated check valve to hold a load. Also, this specific SKU lacks the -S magnet, so it cannot take CMSG/DMSG/EMSG switches.
