Airtac SED Double Rod Cylinder SED100X400
The AirTAC Airtac SED Double Rod Cylinder SED100X400 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 400mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X400
The AirTAC SED100X400 is a double-acting, double-rod profile cylinder dimensionally interchangeable per ISO 15552. Because a 25mm rod exits both end covers, the annulus area is identical on both sides, yielding a perfectly symmetrical 3681N of force at 0.5MPa in both extend and retract directions.
This extruded aluminum barrel unit features field-adjustable air cushioning at both ends (36mm cushion length) to decelerate heavy loads near stroke end. It lacks a standard magnet, meaning no CMSE or DMSE position sensors can be mounted on this specific SKU.
Airtac SED Double Rod Cylinder SED100X400 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X400 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 400 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 SED100X400 Is Used
Injection Mold Platen Shifting
Leverages the 3681N both-way force to shift heavy mold platens, using the twin rods to prevent platen rotation during the long 400mm transfer.
Automated Pallet Diverting
Drives a dual-sided pallet diverter mechanism where the rear rod simultaneously triggers a mechanical flag to confirm the 400mm stroke completion.
Large Press Material Handling
Pushes heavy stamped metal parts out of a 100-ton press, relying on the equal extend and retract force to maintain consistent cycle timing.
Is the Airtac SED Double Rod Cylinder SED100X400 the Right Cylinder?
At 0.5MPa, this 100mm bore generates 3681N each way. If you need less force, the 80mm bore provides 2268N; if your payload is heavier, the 125mm bore offers 5734N. Choose this twin-rod design over a single-rod SE when your application demands anti-rotation stability or requires mounting a rear-rod cam and sensor flag to drive a secondary mechanism.
Since the 400mm stroke exceeds 300mm, ensure external load guides are used to prevent side-loading damage to the rod seals. A plain SED does not hold position on air loss—the piston drifts; for fail-safe holding, select a BSED double-rod lock cylinder. ISO 15552 replacement requires matching the 100mm bore, 400mm 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 SED100X400 FAQ
The SED100X400 delivers equal force in both directions due to the double-rod design. It provides 3681N at 0.5MPa, 5153N at 0.7MPa, and a maximum of 751kgf at 1.0MPa.
The twin rods exiting both ends provide superior anti-rotation guidance for heavy loads and allow the rear rod to mount secondary cams or tooling. It also ensures the speed and force are perfectly matched in both directions.
