Airtac SED Double Rod Cylinder SED100X15
The AirTAC Airtac SED Double Rod Cylinder SED100X15 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 15mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X15
The AirTAC SED100X15 is a double-acting, double-rod ISO 15552 profile cylinder with a 100 mm bore and 15 mm stroke. Because a rod exits both ends, the annulus area is identical on extend and retract. It delivers exactly 3681 N of force each way at 0.5 MPa.
This extruded aluminum unit features adjustable air cushioning at both ends and a PT1/2 port. Since this SKU lacks the -S magnet option, it has no built-in position sensing. The twin 25 mm rods provide rigid anti-rotation guidance for compact, high-force tasks.

| 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 |

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 SED100X15 Is Used
Stamping Press Ejection
Uses the 3681 N both-way force to eject heavy metal panels from a die, with the rear rod simultaneously triggering a mechanical flag to confirm ejection.
PCB Conveyor Diverter
Employs the twin 25 mm rods to push PCBs sideways between belt lines without twisting, relying on the rigid anti-rotation properties for precise 15 mm indexing.
Packaging Flap Folder
Folds heavy cardboard carton flaps synchronously from both sides, ensuring perfectly aligned sealing using the cylinder's equal extend and retract forces.
Is the Airtac SED Double Rod Cylinder SED100X15 the Right Cylinder?
Choose this 100 mm bore if you need substantial equal both-way force in a very short 15 mm stroke. Stepping down to the 80 mm bore drops the output to 2268 N at 0.5 MPa. Stepping up to the 125 mm bore raises it to 5734 N, but requires a slower 30-500 mm/s speed limit versus this model's 30-800 mm/s range.
A double-rod design outperforms a single-rod SE when you need to drive a load from both sides or prevent rotation without external guides. Note that a plain SED does not hold position on air loss; the piston drifts. For fail-safe holding, use a BSED double-rod rod lock. To replace an ISO 15552 unit, match the 100 mm bore, 15 mm stroke, PT1/2 port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SED100X15 FAQ
Because the double-rod design has equal piston area on both sides, force is identical in both directions: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa.
A double-rod cylinder provides equal force and speed in both directions. The rear rod can drive a secondary mechanism or sensor flag, and the twin rods offer superior anti-rotation guidance for the load compared to a single-rod design.
