Airtac SED Double Rod Cylinder SED100X450
The AirTAC Airtac SED Double Rod Cylinder SED100X450 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 450mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X450
The AirTAC SED100X450 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 450mm stroke. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding an equal 3681N of thrust in both directions at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, ensuring clean integration and true ISO 15552 dimensional interchangeability.
This unit uses a PT1/2 port, a Ø25mm rod with an M20x1.5 thread, and field-adjustable air cushions at both ends to manage end-of-stroke impact. It lacks a standard magnet (-S), meaning no CMSE or DMSE position sensing is equipped on this SKU. The rear rod extension is highly effective for mounting a cam or driving a secondary mechanism while guiding the load against rotation.

| 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 |

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 SED100X450 Is Used
Servo Press Positioning
Drives a 3681N both-way servo press head, using the rear rod to trigger a mechanical limit flag upon retraction.
Pallet Diverter Arm
Actuates a heavy diverter on a packaging line, leveraging equal extend and retract forces to push and reset loads consistently.
Injection Mold Ejection
Ejects molded parts symmetrically from both sides, utilizing the anti-rotation stability of the twin rods for precise part removal.
Is the Airtac SED Double Rod Cylinder SED100X450 the Right Cylinder?
Selecting this 100mm bore provides a robust 3681N both-way force at 0.5 MPa (5153N at 0.7 MPa, 751kgf max at 1.0 MPa). If your application requires less force, stepping down to the 80mm bore yields 2268N both ways; if you need more power, the 125mm bore offers 5734N. Choose this double-rod SED over a single-rod SE when your mechanism demands superior anti-rotation stability, dual-side load guidance, or a rear-rod cam for actuating secondary tooling. To replace an existing ISO 15552 cylinder, match the 100mm bore, 450mm stroke, PT1/2 port, and your preferred mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
For a 450mm stroke, ensure external load guides are used to prevent side-loading from bending the twin rods. Remember that a plain SED does not hold position on air loss; the piston drifts, and the adjustable cushion only decelerates near stroke end—it is not a lock. For fail-safe holding, consider an external rod lock or the BSED double-rod rod-lock series.
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 SED100X450 FAQ
Because the double-rod design subtracts rod area from both sides, force is equal in both directions. It delivers 3681N at 0.5 MPa, 5153N at 0.7 MPa, and a maximum of 751kgf at 1.0 MPa.
The twin rods provide equal force both ways and significantly better anti-rotation guidance. The protruding rear rod is also ideal for mounting secondary tooling or cams, and the unit offers true ISO 15552 mounting interchangeability.
