Airtac SED Double Rod Cylinder SED80X145
The AirTAC Airtac SED Double Rod Cylinder SED80X145 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 145mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X145
The AirTAC SED80X145 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80mm bore and 145mm stroke. Because a rod exits both end covers, the annulus area is identical on both sides, yielding an equal force of 2268 N each way at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, ensuring a clean profile that drops in dimensionally for any ISO 15552 footprint.
This configuration omits the standard magnet, meaning no CMSE or DMSE position sensing is possible on this specific SKU without modification. It includes field-adjustable air cushioning at both ends to decelerate the load near stroke end. The twin-rod design provides superior anti-rotation guidance and allows the rear rod end to drive a secondary mechanism or cam.

| 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 SED80X145 Is Used
Web Guiding Mechanisms
Leverages the 3175 N both-way force at 0.7 MPa to tension and steer film or foil webs, using the twin rods to prevent binding during bidirectional edge correction.
Multi-Station Machining Fixtures
Drives a clamping fixture from the front rod while the rear rod simultaneously actuates a chip-clearing blast gate, utilizing the dual-ended output for synchronized automation.
Symmetrical Transfer Arms
Powers an indexing arm that picks and places heavy cast parts, relying on the anti-rotation properties of the double-rod design to maintain strict parallelism.
Is the Airtac SED Double Rod Cylinder SED80X145 the Right Cylinder?
When sizing this model, note that the 80mm bore provides 2268 N of equal both-way force at 0.5 MPa. If your application requires less force, stepping down to the 63mm bore yields 1402 N both ways. If you need more thrust, moving up to the 100mm bore provides 3681 N both ways at 0.5 MPa. Choose this double-rod SED over a single-rod SE when you need to prevent load rotation or require actuation from both ends.
This SKU lacks a magnet (-S), so it cannot support reed or electronic sensors. For a direct ISO 15552 replacement, match the 80mm bore, 145mm stroke, PT3/8 port, and your required mounting from the available Basic, FA, LB, TC, FTC, TCM1, or TCM2 sets. Note that the SED omits the FB, CA, CB, and CR mounts. A plain SED does not hold position on air loss; the piston will drift. For fail-safe holding, consider a BSED double-rod lock cylinder or an external pilot-operated check valve.
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 SED80X145 FAQ
Because the double-rod design subtracts the rod area on both sides, force is equal in both directions. It provides 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and a maximum of 463 kgf at 1.0 MPa.
The twin rods provide superior resistance to side-load rotation and allow the rear rod end to drive a secondary mechanism or cam. It is dimensionally interchangeable per ISO 15552, but offers dual-ended actuation a single-rod SE cylinder cannot.
