Airtac SGCD Dual Rod Cylinder SGCD250X100
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X100 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 100mm 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 SGCD250X100
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 equalize push and pull areas. The G1 air port feeds a bore that safely handles about 14137 N of real work, translating to a vertical lift capacity near 1201 kg with a 2:1 safety margin.
Four steel tie rods clamp the aluminum barrel for high structural rigidity. Because the Ø250 bore uses NBR seals instead of TPU, it is built for robust industrial use, with a Viton H option available for 0-150 C high-temperature environments. A rod exits both covers, providing a symmetric load path that prevents torsional twist.

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 SGCD250X100 Is Used
Heavy Pallet Lifting
Drives large automated pallet elevators where the symmetric twin-rod load path prevents platform twisting under heavy, off-center weights.
Twin-Press Tooling
Simultaneously actuates two forming dies from opposite ends of the machine, ensuring perfectly synchronized parallel closing forces.
Heavy Stamp Deceleration
Uses the 60 mm adjustable air cushions at both stroke ends to smoothly slow massive metal stamping rams without shock loading the covers.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X100 the Right Cylinder?
Sitting at the top of the SGCD range, this 250 mm bore outputs 23562 N each way at 0.5 MPa, stepping up from the 200 mm bore which provides 15079 N. Choose a double-rod configuration when your mechanism requires anti-rotation guidance, twin tooling driven from opposite ends, or a symmetric load path. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. Even with a short 100 mm stroke, external guide rails are recommended to absorb side loads and protect 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 SGCD250X100 FAQ
This double-acting twin-rod cylinder outputs equal force in both directions: 23562 N at 0.5 MPa and 32986 N at 0.7 MPa. The theoretical maximum is 4805 kgf at 1.0 MPa. It features a 250 mm bore, a 50 mm rod, a G1 port, and a 60 mm adjustable cushion at both ends.
The air cushion only decelerates the piston near the stroke ends; it does not hold a load. You must use an external rod lock or pilot-operated check valve to prevent drift from air loss. Additionally, this non-S SKU lacks a magnet and cannot mount position sensors; you need the -S variant for CMSG, DMSG, or EMSG switches.
