Airtac SGCD Dual Rod Cylinder SGCD250X300
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X300 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 300mm 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 SGCD250X300
Generating 23562 N of equal output force in both directions at 0.5 MPa, this large-bore double-rod cylinder is built for heavy-duty symmetric motion. The twin-rod architecture means the piston presents a rod out of each cover, ensuring the pressure area is identical on both faces. This provides inherent anti-rotation guidance and a balanced load path, making it highly effective for driving twin tooling stations or mounting a rear sensor cam. Four steel tie rods clamp the aluminum barrel to the covers, delivering structural rigidity under high stress.
It features a 50 mm piston rod, a G1 air port, and adjustable 60 mm air cushions at both ends. Because the bore is 250 mm, TPU seals are not available; standard NBR packings handle the -20 to +70 C range, with a Viton H option for 0-150 C heat. This non-magnetic SKU cannot accept a sensor, but the -S variant adds a magnet for CMSG/DMSG/EMSG switches. With 23562 N available, you have a safe working load of roughly 14137 N, capable of vertically lifting about 1201 kg 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 SGCD250X300 Is Used
Twin-Spindle Press
Drives two opposing forming tools simultaneously with equal 23562 N force, using the symmetric rod path to keep heavy platens perfectly aligned.
Balanced Lift Platform
Lifts roughly 1201 kg vertically using the equal both-ways pull area, preventing the sagging or drift common in single-rod setups.
Dual-End Transfer
Pushes a part from one belt line to another using the rear rod extension, maintaining a perfectly balanced stroke without requiring external guidance.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X300 the Right Cylinder?
This 250 mm bore sits at the top of the SGCD range, delivering 23562 N both ways at 0.5 MPa. If your application requires less force, stepping down to the 200 mm bore yields 15079 N each way, while the 160 mm bore provides 9425 N. Choose the double-rod configuration when your setup demands anti-rotation stability, twin tooling drives, or a symmetric load path. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mountings, dimensionally interchangeable per the ISO 15552 mounting interface. Note that this specific SKU lacks a magnet and cannot take a sensor; order the -S version for CMSG/DMSG/EMSG switch readiness. For this 300 mm stroke, external load guides are recommended to prevent side-load wear on the rod 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 SGCD250X300 FAQ
It delivers an equal 23562 N of force both ways at 0.5 MPa, and 32986 N both ways at 0.7 MPa. The theoretical maximum is 4805 kgf at 1.0 MPa. It uses a G1 port, a 50 mm rod, and adjustable 60 mm cushions.
No, a plain SGCD does not hold load on air loss; the cushion only decelerates near stroke end, so use an external rod lock or pilot-operated check valve for holding. Additionally, this non-S SKU lacks a magnet and cannot take a sensor; the -S variant is required for CMSG/DMSG/EMSG switches.
