Airtac SGCD Dual Rod Cylinder SGCD250X500S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X500S 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 SGCD250X500S
Delivering 23562 N of equal force in both directions at 0.5 MPa, this large-bore double-rod cylinder uses a 50 mm piston rod exiting both covers on a single piston. The symmetric layout provides a non-rotating anti-twist load path, allowing you to drive two tools simultaneously or mount a sensor cam at the back. It features a G1 air port, M42x2.0 rod thread, and 60 mm adjustable air cushions at each end. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and the body is dimensionally interchangeable per the ISO 15552 mounting interface.
This SGCD250X500S variant includes a built-in piston magnet for CMSG, DMSG, or EMSG position switches. Because this is a 250 mm bore, TPU seals are not available; standard NBR packings handle temperatures from -20 to +70 C, while a Viton H option extends this to 0-150 C. Based on the 0.5 MPa output, you get a safe working load of roughly 14137 N, which translates to lifting about 1201 kg vertically with a 2:1 safety margin.

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 SGCD250X500S Is Used
Twin-Press Stamping
Drives two synchronized forming tools from opposite rod ends, ensuring perfectly balanced impact force without rotational twist.
Heavy Platen Lowering
Lowers massive machining platens with equal push and pull thrust, maintaining precise vertical alignment under heavy loads.
Dual-End Diverting
Actuates sorting gates on both sides of a high-capacity line simultaneously using a single symmetric piston assembly.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X500S the Right Cylinder?
This 250 mm bore sits at the top of the SGCD range, so there is no larger double-rod option available; if your application requires less force, step down to the 200 mm bore which provides 15079 N both ways at 0.5 MPa. Choose a double-rod configuration when you need strict anti-rotation guidance, symmetric load distribution, or twin tooling driven from one piston. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. The -S suffix confirms the magnet is present for CMSG/DMSG/EMSG sensors. Because the 500 mm stroke is substantial, always provide external guide rails to prevent rod bending and side-load damage.
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 SGCD250X500S 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, with a theoretical maximum of 4805 kgf at 1.0 MPa. The air port size is G1.
No, the air cushion only decelerates near the stroke end; it does not lock the piston. You need an external rod lock or pilot-operated check valve to hold a load. The -S suffix means it has a magnet for CMSG, DMSG, and EMSG switches.
