Airtac SED Double Rod Cylinder SED80X140
The AirTAC Airtac SED Double Rod Cylinder SED80X140 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 140mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X140
The AirTAC SED80X140 is a double-acting, double-rod profile cylinder built to the ISO 15552 dimensional interface. Because a 25 mm rod exits both end covers, the annulus area is identical on each side. This means you get exactly 2268 N of output force at 0.5 MPa in both extend and retract directions.
The extruded aluminum barrel lacks external tie rods and includes adjustable air cushions at both ends to tame end-of-stroke impacts. Note this specific SKU lacks a piston magnet, so it cannot host CMSE or DMSE sensors without modification. The rear rod protrusion allows you to mount a secondary cam or tooling flag directly opposite the primary load.
Airtac SED Double Rod Cylinder SED80X140 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED80X140 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 140 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 SED80X140 Is Used
Web Guiding Mechanism
Drives a dual-sided steering roller with 2268 N to correct film alignment. The twin rods prevent yaw during high-speed directional reversals.
Transfer Chuck Actuator
Moves a clamping chuck where the rear rod simultaneously pushes a part-release flag. Equal both-way force ensures consistent timing.
Lifting Fork Pivot
Raises and lowers a machining center fork. The 25 mm twin rods resist torsional twist under asymmetric load, operating at 30-800 mm/s.
Is the Airtac SED Double Rod Cylinder SED80X140 the Right Cylinder?
Stepping down to the 63 mm bore drops your both-way force to 1402 N at 0.5 MPa, while stepping up to the 100 mm bore raises it to 3681 N. Choose this 80 mm bore when a single-rod SE cylinder cannot provide the anti-rotation stability or dual-side guidance your payload requires. The 140 mm stroke keeps side-load moments manageable, but always use external guides for heavy off-center loads.
This cylinder uses a PT3/8 port and M20x1.5 rod thread. You can drop it directly into any ISO 15552 footprint using Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts (FB, CA, CB, and CR are not supported). Remember that a plain SED drifts on air loss; the adjustable cushion decelerates but does not lock. For fail-safe holding, use an external rod lock or a BSED series cylinder.
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 SED80X140 FAQ
Because the double-rod design occupies area on both sides of the piston, 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.
Yes. The SED80X140 is dimensionally interchangeable per ISO 15552. Just match the 80 mm bore, 140 mm stroke, PT3/8 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
