Airtac SGCD Dual Rod Cylinder SGCD250X150
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X150 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 150mm 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 SGCD250X150
Delivering 23562 N of thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod piston to ensure perfectly symmetric load paths. The four steel tie rods clamp the aluminum barrel tight, while the G1 air port feeds the 250 mm bore. Because the rod passes through both covers, the effective area is identical on extension and retraction, yielding equal force and preventing torsional twist.
At 0.5 MPa it handles a safe working load of roughly 14137 N, capable of vertically lifting about 1201 kg with a 2:1 margin. The 60 mm adjustable air cushions at each end absorb heavy kinetic energy, and the NBR seals operate from -20 to +70 C. Note that TPU seals are unavailable for this 250 mm bore, though a Viton H option extends heat resistance to 150 C. This non-magnet SKU cannot mount position sensors.

Theoretical Output Force (Ø250mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 23562 N | 23562 N |
| 0.7 MPa | 32987 N | 32987 N |
| Max (@1.0 MPa) | 5006 kgf | |
Double-rod: the rod passes through both covers, so output force is equal in both directions.

Where the Airtac SGCD Dual Rod Cylinder SGCD250X150 Is Used
Twin-Press Stamping
Drives two synchronized forming tools simultaneously from opposite rod ends, ensuring perfectly balanced impact force across a wide web.
Symmetric Lift Platform
Lifts heavy platens without lateral drift, using the equal pull and push areas to keep the load perfectly level throughout the vertical travel.
Dual-End Diverters
Actuates sorting flaps on both sides of a high-speed belt simultaneously, cutting cycle time by handling two lanes with one piston.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X150 the Right Cylinder?
Sized at the top of the SGCD range, this 250 mm bore provides 23562 N both ways at 0.5 MPa; dropping to the 200 mm bore reduces that equal force to 15079 N. Choose a double-rod configuration when you need anti-rotation stability, twin tooling driven from both ends, or a rear cam for tracking. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. For strokes at or beyond 500 mm, always use external guide rails to prevent side-load binding. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors.
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 SGCD250X150 FAQ
Force is equal in both directions due to the double rod: 23562 N at 0.5 MPa, 32986 N at 0.7 MPa, and a theoretical max of 4805 kgf at 1.0 MPa. Proof pressure is 1.5 MPa.
The air cushion only decelerates near stroke end; it will not hold a load on air loss, so use an external rod lock or pilot-operated check valve. Also, this non-S SKU lacks a magnet and cannot take CMSG/DMSG/EMSG sensors.
