Airtac SED Double Rod Cylinder SED100X240S
The AirTAC Airtac SED Double Rod Cylinder SED100X240S 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 240mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X240S
The AirTAC SED100X240S is a double-acting, double-rod profile cylinder dimensionally interchangeable per ISO 15552 / VDMA 24562. A 25mm rod exits both end covers, yielding an identical annulus area on both sides. This provides equal force in extend and retract, generating 3681N each way at 0.5 MPa.
Equipped with a standard magnet (-S), it interfaces directly with CMSE reed and DMSE electronic sensors. The extruded aluminum barrel omits external tie rods, while field-adjustable air cushioning at both ends decelerates the load near stroke end. The rear rod can mount a cam or secondary tooling, offering superior anti-rotation guidance over single-rod designs.
Airtac SED Double Rod Cylinder SED100X240S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X240S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 240 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 SED100X240S Is Used
CNC Lathe Bar Feeder
Drives push/pull stock feeders with 5153N of equal both-way force at 0.7MPa, using the rear rod for an anti-rotation cam.
Pallet Transfer Line
Transfers heavy workpieces bidirectionally between conveyors, leveraging twin rods to prevent binding during 240mm strokes.
Injection Mold Ejection
Ejects molded parts symmetrically using the 25mm dual rods, ensuring balanced extraction without rotational drift.
Is the Airtac SED Double Rod Cylinder SED100X240S the Right Cylinder?
When sizing this 100mm bore, compare its 3681N both-way output at 0.5 MPa against adjacent bores. Stepping down, the 80mm bore yields 2268N; stepping up, the 125mm bore provides 5734N. Choose this double-rod SED over a single-rod SE when your mechanism requires twin-side load guidance, rear-rod sensing flags, or identical push/pull power.
For stroke lengths at or above 300mm, external guide rails are recommended to manage side loads and prevent binding. Note that an unpowered SED drifts on air loss—the adjustable cushion decelerates but does not lock. For fail-safe holding, select a BSED or an external rod lock. ISO 15552 replacement matching requires 100mm bore, 240mm stroke, PT1/2 port, and a -S magnet.
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 SED100X240S FAQ
Because the double-rod design yields equal annulus areas, force is identical in both directions: 3681N at 0.5 MPa, 5153N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa.
No, a standard SED drifts on air loss. The adjustable air cushion only decelerates near stroke end; it is not a brake. For fail-safe holding, use a BSED double-rod lock or an external pilot-operated check valve.
