Airtac SED Double Rod Cylinder SED100X225
The AirTAC Airtac SED Double Rod Cylinder SED100X225 is a genuine double-acting ISO 15552 double-rod cylinder: a Ø25mm piston rod exits BOTH ends of the Ø100mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 225mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X225
The AirTAC SED100X225 is a double-acting, double-rod profile cylinder built to the ISO 15552 dimensional interface. Because a rod exits both ends, the effective piston area is identical in both directions. This delivers an equal 3681 N of drive force at 0.5 MPa on extend and retract.
It features a 25mm rod with an M20x1.5 thread, PT1/2 ports, and adjustable air cushions at both ends. This specific SKU lacks the magnet option, so it does not support CMSE or DMSE position sensing without modification. The rear rod extension can drive a secondary mechanism or mount a cam.
Airtac SED Double Rod Cylinder SED100X225 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X225 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 225 mm |
| Configuration | Double rod, double acting |
| Port size | PT1/2 |
| Rod thread | M20×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C (0–150 °C with FKM seals) |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 36 mm |
| Max stroke | Up to 1500 mm |
Specifications follow the official AirTAC SED datasheet and ISO 15552 / VDMA 24562 dimensions. Confirm against the product label before installation. Port options: PT (standard) / G (BSPP).
Theoretical Output Force (Ø100mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 3682 N |
| 0.7 MPa | 5154 N |
| Max (@1.0 MPa) | 751 kgf |
Because a rod exits both ends, the effective piston area — and therefore the force — is identical on extend and retract. Actual usable force is lower than theoretical; size with a safety margin.

Where the Airtac SED Double Rod Cylinder SED100X225 Is Used
Lifting Die Sets
Drives heavy stamping dies with 3681 N at 0.5 MPa. The twin rods prevent the heavy die from twisting during vertical lift.
Pallet Diverters
Pushes loaded pallets from one conveyor line to another. Equal force both ways ensures smooth extension and retraction under high friction.
Press Ejection
Ejects formed metal parts from a press bed. The rear rod end mounts a cam to trigger the next machine cycle simultaneously.
Is the Airtac SED Double Rod Cylinder SED100X225 the Right Cylinder?
Select this 100mm bore when you need substantial equal both-way force. Stepping down to an 80mm bore drops the output to 2268 N at 0.5 MPa, while stepping up to a 125mm bore raises it to 5734 N. Choose this double-rod SED over a single-rod SE when your application requires anti-rotation stability, dual-side guidance, or rear-rod tooling.
For a 225mm stroke, ensure external guides support the load to prevent side-loading on the seals. This cylinder is a direct dimensional replacement for any ISO 15552 double-rod unit with matching bore, stroke, PT1/2 port, and mounting. Note that a plain SED does not hold position on air loss; the piston drifts. For fail-safe holding, use a BSED rod lock or external check valve.
Quick checklist
- ✓ Equal force/speed both directions needed?
- ✓ Back-rod space for tooling or a flag
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Support both rod ends; avoid side load.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB/FA/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SED Double Rod Cylinder SED100X225 FAQ
Because the rod occupies both sides of the piston, force is equal in both directions. It provides 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa.
Yes. The SED is an ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders of the same bore and stroke. Just match your mounting style and PT1/2 port.
