Airtac SED Double Rod Cylinder SED100X280
The AirTAC Airtac SED Double Rod Cylinder SED100X280 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 280mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X280
The AirTAC SED100X280 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 280mm stroke. Because a 25mm rod occupies both piston sides, the annulus area is identical in each direction, yielding an equal 3681 N of thrust and pull at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, ensuring a clean, dimensionally interchangeable ISO 15552 footprint.
This unit lacks the -S magnet option, meaning no CMSE or DMSE position sensing is integrated on this SKU. Field-adjustable air cushions at both ends safely decelerate the 25mm twin rods near stroke limits. The rear rod extension can drive a secondary mechanism or mount a physical limit flag, while the dual-rod geometry provides superior anti-rotation guidance compared to a single-rod SE cylinder.
Airtac SED Double Rod Cylinder SED100X280 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X280 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 280 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 SED100X280 Is Used
CNC Lathe Bar Feeder
Drives pusher tubes to load raw bar stock into CNC spindles, using the 3681 N equal both-way force to advance and retract material smoothly without rotational drift.
Injection Mold Ejection
Utilizes the rear rod end to mount a mechanical cam, actuating a secondary mold release mechanism precisely when the main stroke completes its 280mm travel.
Pallet Transfer Stopper
Applies 5153 N at 0.7 MPa to halt heavy pallets on a conveyor line, with the twin-rod design ensuring the stopper blade remains perfectly perpendicular to the load.
Is the Airtac SED Double Rod Cylinder SED100X280 the Right Cylinder?
Select this 100mm bore when your application requires 3681 N of equal bidirectional force at 0.5 MPa (5153 N at 0.7 MPa, 751 kgf max at 1.0 MPa). If you need less force, step down to the 80mm bore providing 2268 N both ways; for heavier loads, the 125mm bore offers 5734 N. The twin-rod design is preferred over a single-rod SE when the load demands anti-rotation stability, dual-side guidance, or rear-rod tooling.
For a drop-in ISO 15552 replacement, match the 280mm stroke, PT1/2 port, and M20x1.5 rod thread. Mounting choices include Basic, FA, LB, TC, FTC, TCM1, or TCM2 (omitting FB/CA/CB/CR). At 280mm stroke, maintain external guide rails to manage potential side loads. Note that a plain SED does not hold position on air loss; the piston drifts, and the adjustable cushion only decelerates near stroke end. For fail-safe holding, specify a BSED double-rod rod lock.
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 SED100X280 FAQ
Because the 25mm rod exits both ends, the effective area is identical in both directions. The SED100X280 generates 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa, equally on extend and retract.
Yes. It is a true ISO 15552 profile cylinder with no external tie rods. To drop-in replace an existing unit, match the 100mm bore, 280mm stroke, PT1/2 port, and select from the available Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interfaces.
