Airtac SED Double Rod Cylinder SED100X400S
The AirTAC Airtac SED Double Rod Cylinder SED100X400S 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 SED100X400S
The AirTAC SED100X400S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a 25mm rod exits both ends, the effective piston area is identical in both directions, yielding an equal force of 3681 N each way at 0.5 MPa. The extruded aluminum barrel includes sensor grooves, and the -S option provides a magnet for DMSE electronic or CMSE reed switches.
Equipped with field-adjustable air cushioning at both ends, this 100mm bore unit decelerates the load near the 400mm stroke terminations. The rear rod extension can drive a secondary mechanism or mount a cam, while providing superior anti-rotation guidance compared to a single-rod SE cylinder.

| 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 SED100X400S Is Used
Injection Mold Ejection
Drives dual-sided ejection plates in plastic injection machinery, utilizing the 3681 N both-way force to push and pull heavy molds symmetrically without rotation.
Pallet Transfer Indexing
Indexes heavy pallets on conveyor lines where the rear rod mounts a cam to trigger downstream sensors, ensuring synchronized high-mass handling at 5153 N.
Press Feeders
Feeds heavy coil stock into stamping presses, leveraging the 400mm stroke and twin-rod anti-rotation stability to guide material precisely under high cyclic loads.
Is the Airtac SED Double Rod Cylinder SED100X400S the Right Cylinder?
Select this 100mm bore when an application requires 3681 N of both-way force at 0.5 MPa (5153 N at 0.7 MPa, max 751 kgf at 1.0 MPa). If you need less force, the 80mm bore provides 2268 N both ways at 0.5 MPa; stepping up to the 125mm bore yields 5734 N. For drop-in ISO 15552 replacements, match the 400mm stroke, PT1/2 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
At 400mm stroke, the extended twin rods increase susceptibility to side-loading; external guides are recommended to prevent binding. Note that the air cushion only decelerates the load and does not hold position on air loss—use a BSED rod-lock cylinder or external pilot-operated check valve for fail-safe holding.
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 SED100X400S FAQ
Because the double-rod design has equal piston areas on both sides, the force is identical in extend and retract directions: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa.
The twin-rod design provides equal force and speed both ways, improves load stability and anti-rotation, and allows the rear rod to drive a secondary mechanism or sensor cam. It is dimensionally interchangeable with ISO 15552 double-rod cylinders.
