Airtac SED Double Rod Cylinder SED100X15S
The AirTAC Airtac SED Double Rod Cylinder SED100X15S 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 SED100X15S
The AirTAC SED100X15S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 15mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract. It generates 3681 N of thrust each way at 0.5 MPa. The extruded aluminum barrel includes sensor grooves, and the -S magnet option enables position tracking with CMSE reed or DMSE electronic sensors.
This design provides superior anti-rotation guidance for heavy loads compared to a single-rod SE cylinder. The rear rod extension can drive a secondary mechanism or mount a cam. Adjustable air cushions at both ends decelerate the piston near stroke end. Remember that an air cushion is not a lock; the piston drifts on air loss, so use a BSED double-rod rod lock for fail-safe holding.
Airtac SED Double Rod Cylinder SED100X15S Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 15 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 SED100X15S Is Used
Servo Press Sub-assembly
Drives a short 15mm stamping head with 3681 N at 0.5 MPa, using the twin rods to prevent chassis binding under off-center loads.
Synchronized Gripper Cam
Uses the rear rod extension to actuate a secondary release cam, maintaining equal push and pull speeds for automated clamping.
Web Guide Straightener
Stabilizes a heavy material guide roll in a printing press, relying on the 100mm bore's 5153 N at 0.7 MPa for precise tension control.
Is the Airtac SED Double Rod Cylinder SED100X15S the Right Cylinder?
Choose this 100mm bore when your application requires 3681 N of force at 0.5 MPa in both directions. If you need less force, the 80mm bore provides 2268 N both ways. If you need more, the 125mm bore yields 5734 N both ways. The twin-rod design is essential for short-stroke applications requiring strict anti-rotation stability or rear-rod tooling. To replace an ISO 15552 cylinder, match the 100mm bore, 15mm stroke, PT1/2 port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2). The 25mm rod uses an M20x1.5 thread.
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 SED100X15S FAQ
Because the rod occupies both sides of the piston, the 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.
The twin rods prevent rotation and allow the rear rod to drive external tooling or a sensor flag. It is dimensionally interchangeable per ISO 15552, but note the overall length is longer to accommodate the rear rod, and it omits FB, CA, CB, and CR mounts.
