Airtac SED Double Rod Cylinder SED100X25
The AirTAC Airtac SED Double Rod Cylinder SED100X25 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 25mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X25
The AirTAC SED100X25 is a double-acting, double-rod profile cylinder built to the ISO 15552 dimensionally interchangeable interface. A 25mm stroke is driven by twin 25mm rods exiting both end covers, yielding equal force in extend and retract. You get 3681 N of thrust each way at 0.5 MPa, scaling to 5153 N at 0.7 MPa.
Because the rear rod protrudes, you can mount a secondary cam or sensor flag directly opposite the primary work tool. This SKU lacks the -S magnet, so there is no position sensor on this cylinder. Field-adjustable air cushions at both ends manage impact deceleration over the 36mm cushion length.
Airtac SED Double Rod Cylinder SED100X25 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X25 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 25 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 SED100X25 Is Used
Web Guiding Brakes
Applies 3681 N of balanced clamping force to paper or film converting lines, using the twin rods to prevent chatter during rapid directional tension shifts.
Multi-Axis Milling Stops
Drives a rear-rod cam to trip mechanical limit switches on machining centers, leveraging the short 25mm stroke for high-cycle index positioning.
Pallet Diverters
Pushes heavy pallets evenly across conveyor lanes, relying on the equal both-way force to retract the diverter arm without stalling under load.
Is the Airtac SED Double Rod Cylinder SED100X25 the Right Cylinder?
Choose this 100mm bore when you need high push-pull symmetry that a single-rod SE cannot provide. If 3681 N both ways is excessive, step down to the 80mm bore for 2268 N at 0.5 MPa. If you need more power, the 125mm bore provides 5734 N. The twin 25mm rods with M20x1.5 threads enhance side-load resistance and prevent load rotation. For fail-safe position holding on air loss, note that the SED piston drifts; the cushions decelerate but do not lock. Select the BSED double-rod rod lock or an external pilot-operated check valve instead. To replace an ISO 15552 unit, match the 100mm bore, 25mm stroke, PT1/2 port, and mounting style (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 SED100X25 FAQ
Because the double-rod design subtracts rod area from both sides, force is equal in both directions. It delivers 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 superior anti-rotation guidance and allow mounting a secondary tool, cam, or sensor flag on the rear rod. It also drops into existing ISO 15552 mounting footprints using Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts.
