Airtac SGCD Dual Rod Cylinder SGCD250X50
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X50 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 50mm 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 SGCD250X50
Delivering 23562 N of thrust in both directions at 0.5 MPa, this large-bore double-rod cylinder eliminates the area differential found in single-rod units. It yields a safe working load of roughly 14137 N, capable of vertically lifting about 1201 kg with a 2:1 margin. Four steel tie rods clamp the aluminum barrel to the covers, providing rigid structural integrity for heavy industrial service.
The piston passes through both covers, creating a symmetric load path that resists torsional twisting and allows dual-tool mounting. It features a G1 air port and adjustable 60 mm cushions at each end. Because this is a 250 mm bore, TPU seals are unavailable; standard NBR packings handle temperatures from -20 to +70 C, with a Viton H option extending service up to 150 C.

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 SGCD250X50 Is Used
Twin-Spindle Press
Drives two opposing forming tools simultaneously with equal 23562 N force, keeping the press bed perfectly balanced without requiring external mechanical synchronization.
Heavy Platen Lowering
Lowers heavy stamping platens with a symmetric load path that prevents guide bushing bind, while the 60 mm cushions absorb kinetic energy at the bottom of the stroke.
Symmetric Ejector Assembly
Uses the protruding rear rod to eject a finished part from the back of a mold while the front rod retracts a raw blank, maintaining an identical push and pull profile.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X50 the Right Cylinder?
As the largest bore in the range, the 250 mm sits at the high edge, offering far more power than the 200 mm option which provides 15079 N both ways at 0.5 MPa. Choose this double-rod configuration when your mechanism requires strict anti-rotation guidance, symmetric load distribution, or a rear rod end to actuate a secondary mechanism. Mounting hardware includes FA, LB, TC, FTC, TCM1, and TCM2 brackets conforming to the ISO 15552 mounting interface. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors; add the -S option if you require position detection. For any application exceeding 500 mm of stroke, always use external guide rails to prevent side-load damage to the seals.
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 SGCD250X50 FAQ
Because the rod exits both ends, force is equal in both directions: 23562 N at 0.5 MPa and 32986 N at 0.7 MPa. The theoretical maximum is 4805 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a 1.5 MPa proof pressure.
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. Additionally, this SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG sensors—you need the -S variant for position detection.
