Airtac SED Double Rod Cylinder SED80X5
The AirTAC Airtac SED Double Rod Cylinder SED80X5 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 5mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X5
The AirTAC SED80X5 is a double-acting, double-rod ISO 15552 profile cylinder with a remarkably short 5mm stroke. Because a Ø25mm rod exits both end covers, the effective piston area is identical in both directions. This means you get exactly 2268 N of force at 0.5 MPa on both extend and retract strokes, ensuring perfectly balanced motion control.
This extruded aluminum profile cylinder omits external tie rods for a clean exterior. It features field-adjustable air cushioning at both ends to tame end-of-stroke impacts. Note that this specific SKU lacks a magnet (-S), so it will not trigger CMSE or DMSE sensors without modification.

| 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 |

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 SED80X5 Is Used
Stamping Pin Press
Provides 2268 N of equal both-way force to drive a short 5mm stamping pin, using the rear rod to eject the part simultaneously.
Panel Alignment Jig
Uses the twin-rod anti-rotation特性 to push a heavy metal panel into a weld fixture precisely over a 5mm gap without twisting.
Dual-Side Clamping
Clamps a workpiece from both sides simultaneously, utilizing the through-rod design to synchronize opposing 3175 N grip forces at 0.7 MPa.
Is the Airtac SED Double Rod Cylinder SED80X5 the Right Cylinder?
Choose this 80mm bore if your application demands high force in an extremely compact footprint. If you need less force, step down to the 63mm bore which provides 1402 N at 0.5 MPa. If you require more power, the 100mm bore offers 3681 N at 0.5 MPa. The twin-rod design is superior to a single-rod SE cylinder when you need anti-rotation stability or want to mount a cam and sensor flag on the rear rod. Remember that a plain SED does not hold position on air loss; the piston will drift. For fail-safe holding, use a BSED double-rod rod lock or an external pilot-operated check valve. To replace an existing ISO 15552 cylinder, match the 80mm bore, 5mm stroke, PT3/8 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 SED80X5 FAQ
Because the double-rod design subtracts rod area from both sides, force is equal in both directions. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and reaches a maximum of 463 kgf at 1.0 MPa.
The through-rod provides equal force and speed in both directions, offers better load guidance against rotation, and allows you to mount tooling or a sensor flag on the rear rod end. Just ensure you leave clearance for the rear rod protrusion.
