Airtac SED Double Rod Cylinder SED100X145
The AirTAC Airtac SED Double Rod Cylinder SED100X145 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 145mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X145
The AirTAC SED100X145 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 145mm stroke. Because a 25mm rod occupies both piston sides, the annulus area is identical in both directions, yielding an equal extend and retract force of 3681N at 0.5MPa. The extruded aluminum barrel omits external tie rods for a clean profile.
This unit lacks the -S magnet option, meaning no CMSE or DMSE position sensing is available on this SKU. It includes field-adjustable air cushioning at both ends (36mm stroke) to decelerate loads near stroke end. Note the longer overall length versus a single-rod SE, requiring rear-rod clearance for the protruding shaft.
Airtac SED Double Rod Cylinder SED100X145 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X145 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 145 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 SED100X145 Is Used
Louver Press Machine
Applies 5153N of equal both-way force to form metal louvers, using the twin rods to prevent deflection during high-speed reciprocation.
Dual-Side Transfer Chuck
Transfers heavy automotive castings between stations, utilizing the rear rod end to mirror a secondary cam action without adding a second cylinder.
Textile Calendering
Drives a calendering nip with perfectly balanced 3681N force at 0.5MPa in both directions, ensuring uniform fabric thickness across the web.
Is the Airtac SED Double Rod Cylinder SED100X145 the Right Cylinder?
Select this 100mm bore when an application demands 5153N of equal both-way force at 0.7MPa. If you need less force, step down to the 80mm bore providing 2268N at 0.5MPa; if you need more, step up to the 125mm bore offering 5734N at 0.5MPa. The twin rods provide superior anti-rotation guidance and allow rear-rod tooling or cam actuation. Remember, a plain SED does not hold position on air loss—the piston drifts. For fail-safe holding, use a BSED double-rod rod lock. As a true ISO 15552 cylinder, it is dimensionally interchangeable via its mounting interface (Basic, FA, LB, TC, FTC, TCM1, TCM2—omitting FB/CA/CB/CR). Standard PT1/2 ports and M20x1.5 rod threads apply.
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 SED100X145 FAQ
Because the double-rod design subtracts rod area from both sides, force is equal in both directions: 3681N at 0.5MPa, 5153N at 0.7MPa, and a maximum of 751kgf at 1.0MPa.
Yes. The SED100X145 is dimensionally interchangeable per ISO 15552 / VDMA 24562 profile standards. Match the 100mm bore, 145mm stroke, PT1/2 port, and mounting interface (Basic, FA, LB, TC, FTC, TCM1, TCM2) for a drop-in replacement.
