Airtac SED Double Rod Cylinder SED100X30S
The AirTAC Airtac SED Double Rod Cylinder SED100X30S 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 30mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X30S
The AirTAC SED100X30S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 30mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding equal force and speed in both directions. You get 3681 N of thrust each way at 0.5 MPa, and 5153 N at 0.7 MPa. The extruded aluminum barrel contains no external tie rods, ensuring a clean profile.
Equipped with a standard magnet (-S), this cylinder interfaces directly with CMSE reed and DMSE electronic sensors for precise end-of-stroke positioning. The rear rod extension is highly useful for mounting secondary tooling, a cam, or a mechanical flag. Field-adjustable air cushions at both ends manage impact deceleration over 36mm.

| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 30 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 SED100X30S Is Used
Multi-Spindle Drilling Heads
Drives dual-side drilling fixtures using the 3681 N both-way force, utilizing the rear rod for a synchronized depth-limit cam.
Heavy Transfer Pushers
Moves pallets on assembly lines with balanced extend and retract thrust, leveraging the twin rods to prevent load twisting.
Press Die Ejection
Ejects stamped parts equally on advance and return, using the M20x1.5 rod threads for secure die-plate mounting.
Is the Airtac SED Double Rod Cylinder SED100X30S the Right Cylinder?
Choose this 100mm bore when your application requires substantial equal both-way force, here 3681 N at 0.5 MPa. If you need less force, the 80mm bore provides 2268 N at 0.5 MPa; if you need more, the 125mm bore offers 5734 N. The twin-rod design provides superior anti-rotation stability and dual-side load guidance compared to a single-rod SE cylinder. Remember that a plain SED does not hold position on air loss—the piston drifts. For fail-safe holding, use a BSED double-rod lock or external pilot-operated check valve. To replace an ISO 15552 unit, match the 100mm bore, 30mm stroke, PT1/2 port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2—omitting FB/CA/CB/CR).
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 SED100X30S FAQ
Because the double-rod design equalizes the piston area, output 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.
The twin rods provide equal force and speed both ways, prevent load rotation, and allow the rear rod to drive secondary tooling. It is dimensionally interchangeable per ISO 15552, serving as a direct drop-in replacement for other double-rod profile cylinders.
