Airtac SED Double Rod Cylinder SED100X900
The AirTAC Airtac SED Double Rod Cylinder SED100X900 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 900mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X900
The AirTAC SED100X900 is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a 25mm rod exits both end covers, the annulus area is identical on extend and retract. This gives you exactly 3681 N of output force at 0.5 MPa in both directions.
This 900mm stroke unit uses a PT1/2 port and features adjustable air cushions at both ends to tame kinetic energy. Note this SKU lacks a piston magnet, so it cannot host CMSE or DMSE sensors. The extruded aluminum barrel drops directly into existing ISO 15552 mounting footprints.
Airtac SED Double Rod Cylinder SED100X900 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X900 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 900 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 SED100X900 Is Used
Web Guiding Mechanism
Drives a 900mm correction beam in film lines. The twin rods prevent twist under the 3681 N force, keeping material tracking true.
Large Press Ejection
Pushes stamped parts out of a press bed. The rear rod simultaneously trips a mechanical flag to confirm the 5153 N ejection stroke completed.
Dual-Side Conveyor Gate
Actuates a long diverter gate from one end while the opposite rod end mirrors the motion, synchronizing a 900mm traverse without extra linkage.
Is the Airtac SED Double Rod Cylinder SED100X900 the Right Cylinder?
Selecting this 100mm bore gives 3681 N both ways at 0.5 MPa. If your drive is over-specified, stepping down to the 80mm bore yields 2268 N. If you need more muscle, the 125mm bore provides 5734 N. At a 900mm stroke, external guide rails are critical to prevent side-loading damage to the rod seals.
Choose this double-rod over a single-rod SE when you need superior anti-rotation control or a rear rod to mount a cam and limit flag. Remember that air cushions only decelerate the load near stroke end; they do not hold position on air loss. For fail-safe holding, use an external rod lock or a BSED double-rod lock cylinder.
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 SED100X900 FAQ
Because the double-rod design occupies piston area on both sides, 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 a true ISO 15552 profile cylinder, so it is dimensionally interchangeable with other ISO 15552 double-rod cylinders. Just match the 100mm bore, 900mm stroke, PT1/2 port, and mounting style.
