Airtac SGCD Dual Rod Cylinder SGCD250X1000S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X1000S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 1000mm 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 SGCD250X1000S
Delivering 23562 N of equal thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod piston to balance the load path completely. The rod exits both covers, yielding identical push and pull areas that prevent twist during heavy strokes. It provides 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, and the G1 air port feeds a double-acting mechanism running at 30-500 mm/s. Because this is a 250 mm bore, TPU seals are unavailable; standard NBR packings handle the -20 to +70 C range, while a Viton H option extends heat resistance to 150 C. The -S suffix indicates a built-in magnet for CMSG, DMSG, or EMSG switches. Note that the 60 mm adjustable air cushions only decelerate the piston near the end of travel; they do not lock the load on air loss, so fit an external rod lock if you need strict holding.

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 SGCD250X1000S Is Used
Twin-Side Pressing Station
Drives two opposing forming tools simultaneously from a single piston, ensuring perfectly balanced 23562 N clamping force on both ends without torsional twist.
Heavy Platen Lowering
Uses the rear rod as a rigid anti-rotation guide while lowering heavy industrial molds, keeping the platen perfectly level throughout the 1000 mm descent.
Symmetric Divert Gate
Employs the equal push and pull thrust to actuate a heavy diverting gate on a high-speed line, maintaining stable kinetics regardless of travel direction.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X1000S the Right Cylinder?
This 250 mm bore sits at the top edge of the SGCD range, offering 23562 N of equal both-ways force at 0.5 MPa. If your application requires less thrust, the 200 mm bore provides 15079 N, but for extreme loads this is the maximum option. A double-rod design is the right call when you need anti-rotation guidance, symmetric load distribution, twin tooling driven from both ends, or a rear rod acting as a sensor cam. Mounting choices include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The -S magnet enables position sensing with CMSG, DMSG, or EMSG switches. Because the stroke is 1000 mm, you must use external guides to prevent rod bending and manage side loads on this large-bore actuator.
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 SGCD250X1000S FAQ
Force is equal 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. It uses a G1 air port and an M42x2.0 rod thread.
The twin-rod layout creates a symmetric load path that resists rotation and delivers identical push/pull areas. The -S suffix adds a piston magnet for CMSG, DMSG, or EMSG position switches.
