Airtac SED Double Rod Cylinder SED100X300
The AirTAC Airtac SED Double Rod Cylinder SED100X300 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 300mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X300
The AirTAC SED100X300 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100 mm bore and 300 mm stroke. Because a 25 mm rod extends from both end covers, the annulus area is identical on both sides. This means you get exactly 3681 N of force in both extend and retract directions at 0.5 MPa.
This extruded aluminum unit lacks external tie rods and provides field-adjustable air cushioning at both ends over a 36 mm stroke. This specific SKU is built without a magnet, meaning it cannot host CMSE or DMSE position sensors. The rear rod protrusion is excellent for mounting a cam or driving a secondary mechanism.
Airtac SED Double Rod Cylinder SED100X300 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X300 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 300 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 SED100X300 Is Used
Multi-Spindle Drilling Heads
Drives twin drilling heads simultaneously. The double rod provides rigid anti-rotation guidance for the 3681 N thrust required to plunge tooling, while the 300 mm stroke handles deep cutting cycles.
Pallet Transfer Pushers
Indexes heavy pallets along a conveyor line. The through-rod design allows a rear-mounted cam to trigger a mechanical valve, using 5153 N at 0.7 MPa to overcome friction without twisting.
Panel Board Lamination Presses
Applies uniform clamping pressure from both sides during adhesive curing. The equal both-way force prevents uneven lamination, and the 300 mm stroke accommodates thick substrate stacks.
Is the Airtac SED Double Rod Cylinder SED100X300 the Right Cylinder?
Select this 100 mm bore when you need 3681 N of equal bidirectional force at 0.5 MPa (or 5153 N at 0.7 MPa). If your application requires less force, step down to the 80 mm bore which provides 2268 N both ways. If you need more power, the 125 mm bore yields 5734 N. The twin-rod design inherently resists rotation better than a single-rod SE cylinder.
With a 300 mm stroke, you must account for side loads; use external guide rails to prevent rod binding and premature seal wear. Remember that a standard SED does not hold position on air loss—the piston will drift. For fail-safe holding, consider a BSED double-rod rod lock cylinder. This model uses a PT1/2 port and accepts Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts (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 SED100X300 FAQ
Because the double-rod design yields equal area on both sides, it outputs 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa in both the extend and retract directions.
Yes, it is dimensionally interchangeable per ISO 15552 / VDMA 24562. Just ensure you have rear-rod clearance for the through-rod, verify your PT1/2 port connection, and select a compatible mount from the available Basic, FA, LB, TC, FTC, TCM1, or TCM2 options.
