Airtac SED Double Rod Cylinder SED80X450
The AirTAC Airtac SED Double Rod Cylinder SED80X450 is a genuine double-acting ISO 15552 double-rod cylinder: a Ø25mm piston rod exits BOTH ends of the Ø80mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 450mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X450
The AirTAC SED80X450 is a double-acting, double-rod profile cylinder built to the ISO 15552 interface. A 25mm rod exits both end covers, yielding identical annulus areas. This means you get equal force in both directions—about 2268N at 0.5 MPa and 3175N at 0.7 MPa.
The extruded aluminum barrel lacks external tie rods and includes field-adjustable air cushioning at both ends. Because this SKU lacks the -S magnet option, it has no onboard position sensing. The rear rod extension is excellent for mounting a cam or driving a secondary mechanism.
Airtac SED Double Rod Cylinder SED80X450 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED80X450 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 450 mm |
| Configuration | Double rod, double acting |
| Port size | PT3/8 |
| 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 (Ø80mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 2268 N |
| 0.7 MPa | 3175 N |
| Max (@1.0 MPa) | 463 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 SED80X450 Is Used
Web Guiding Mechanism
Drives a parallel adjusting roller in a film converting line. The twin rods prevent yaw, while the 2268N both-way force precisely tensions the web in either direction.
Multi-Station Lift Gate
Actuates a synchronized lifting platform in an automated assembly cell. The rear rod end simultaneously pushes a secondary shuttle, utilizing the equal extend and retract dynamics.
Indexing Conveyor Drive
Shifts a heavy palletized fixture between machining stations. The 3175N available at 0.7 MPa handles the mass, while the through-rod design mounts a physical stop cam on the back end.
Is the Airtac SED Double Rod Cylinder SED80X450 the Right Cylinder?
This 80mm bore provides 2268N of both-way force at 0.5 MPa. If you need less, the 63mm bore offers 1402N. For heavier drives, the 100mm bore provides 3681N. The twin-rod design inherently resists torsional load and provides superior anti-rotation guidance compared to a single-rod SE cylinder.
At a 450mm stroke, the extended rod length demands strict external guide alignment to prevent side-load binding. Remember that the adjustable air cushion only decelerates the load near stroke end; it is not a brake. A plain SED will drift on air loss, so specify a BSED or external rod lock for fail-safe position holding. This unit uses a PT3/8 port and M20x1.5 rod thread.
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 SED80X450 FAQ
Because the double-rod design creates equal piston areas on both sides, force is identical in both directions. It delivers 2268N at 0.5 MPa, 3175N at 0.7 MPa, and a maximum of 463 kgf at 1.0 MPa.
Yes. It shares the exact ISO 15552 mounting footprint and can drop in for other double-rod profile cylinders. Just ensure you have rear-rod clearance, as the overall length is longer than a single-rod version, and note it uses a PT3/8 port.
