Airtac SED Double Rod Cylinder SED100X100S
The AirTAC Airtac SED Double Rod Cylinder SED100X100S 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 100mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X100S
The AirTAC SED100X100S is a double-acting, double-rod profile cylinder built to the ISO 15552 standard. Because a 25 mm rod exits both ends, the annulus area is identical on extend and retract. This means you get exactly 3681 N of force each way at 0.5 MPa, with zero directional imbalance.
The extruded aluminum barrel has no external tie rods, keeping the profile clean. The S suffix means a magnet is installed for position sensing. You can mount CMSE reed or DMSE electronic switches directly into the barrel groove. The rear rod extension is perfect for driving a secondary mechanism or mounting a physical limit flag.

| Bore size | Ø100 mm |
| Stroke | 100 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 SED100X100S Is Used
Servo Press Substrate
Drives a precision stamping head with 5153 N at 0.7 MPa. The twin rods prevent wrenching under off-center loads, ensuring the press ram stays perfectly parallel.
Web Guide Braking
Actuates a tensioning brake in a paper mill. The protruding rear rod mounts a physical cam that mechanically triggers a knife cutoff at the exact stroke endpoint.
Shuttle Transfer Gate
Shifts a heavy pallet shuttle between conveyor lanes. Equal both-way force means the 3681 N push and pull are identical, allowing symmetrical cycle timing.
Is the Airtac SED Double Rod Cylinder SED100X100S the Right Cylinder?
At 0.5 MPa, this 100 mm bore yields 3681 N both ways. If you need less force, step down to the 80 mm bore for 2268 N. If your load is heavier, the 125 mm bore provides 5734 N. The twin-rod design inherently resists torsional rotation better than a single-rod SE cylinder, which is vital for guided presses. Remember that a plain SED100X100S will drift on air loss; the adjustable air cushions only decelerate the piston near stroke end. For fail-safe holding, use a BSED double-rod lock. To replace an ISO 15552 unit, match the 100 mm bore, 100 mm stroke, PT1/2 port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or 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 SED100X100S FAQ
Because the double-rod design has equal piston area on both sides, force is identical 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.
The twin rods offer superior anti-rotation guidance for heavy loads. The rear rod protrusion also allows you to mount a sensor flag or drive a secondary mechanism directly from the back of the cylinder.
