Airtac SGCD Dual Rod Cylinder SGCD250X600S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X600S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 600mm 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 SGCD250X600S
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 passing through both covers to equalize pressure areas. The four steel tie rods clamp the aluminum barrel securely, and the G1 air port feeds a double-acting mechanism that runs at 30-500 mm/s.
Because the rod exits both ends, it provides a symmetric load path and prevents rotation without extra guides. The built-in magnet (-S) supports CMSG, DMSG, and EMSG switches for end-position sensing. This 250 mm bore omits TPU seals for NBR packing, though a Viton H option extends operation to 150 C. With a 0.5 MPa input, the safe working load is roughly 14137 N, capable of lifting about 1201 kg vertically with a 2:1 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 SGCD250X600S Is Used
Twin-Press Stamping
Drives two synchronized forming tools simultaneously from opposite rod ends, utilizing the equal 32986 N force at 0.7 MPa for balanced metalworking.
Heavy Platen Lowering
Lowers large machining platens with a symmetric load path that resists torsional twist, safely managing a 1201 kg vertical lift at 0.5 MPa.
Dual-End Diverting
Actuates heavy conveyor diverters using both rod ends to push and reset sorting gates without requiring a separate return cylinder.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X600S the Right Cylinder?
This 250 mm bore sits at the top of the SGCD range, offering 23562 N each way at 0.5 MPa; stepping down to the 200 mm bore drops the equal force to 15079 N. Choose a double-rod design when you need anti-rotation stability, twin tooling driven from one piston, or a rear rod to act as a sensor cam. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. The -S suffix ensures piston magnet readiness for CMSG/DMSG/EMSG sensors. Because the 600 mm stroke is substantial, always provide external guide support to prevent rod bending under side loads.
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 SGCD250X600S FAQ
The double-rod design yields equal force both ways: 23562 N at 0.5 MPa and 32986 N at 0.7 MPa, with a theoretical max of 4805 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, and the G1 port feeds the 250 mm bore.
No, the air cushion only decelerates near stroke end; a plain cylinder drifts on air loss, so use an external rod lock or pilot-operated check valve for holding. This 250 mm bore uses NBR seals (TPU is unavailable) with a Viton H option for 0-150 C environments.
