Airtac SED Double Rod Cylinder SED80X180
The AirTAC Airtac SED Double Rod Cylinder SED80X180 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 180mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X180
The AirTAC SED80X180 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 180 mm stroke and 80 mm bore. Because a 25 mm rod extends from both end covers, the annulus area is identical on extend and retract. This generates exactly 2268 N of thrust each way at 0.5 MPa, ensuring perfectly balanced bidirectional motion.
This unit uses an extruded aluminum barrel without external tie rods and includes field-adjustable air cushioning at both ends (36 mm cushion length) to tame end-of-stroke impacts. This specific SKU lacks the -S magnet option, meaning it cannot host CMSE reed or DMSE electronic sensors without modification. The rear rod protrusion allows you to mount a secondary cam or tooling fixture directly opposite the primary work end.

| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 180 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 |

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 SED80X180 Is Used
Servo-Press Ejection
Uses the 3175 N both-way force at 0.7 MPa to push and retract a stamping ejection pin, relying on the twin 25 mm rods to prevent binding under off-center loads.
Shuttle Transfer Lane
Drives a dual-sided workpiece shuttle where the rear rod simultaneously trips a mechanical flag, keeping cycle speeds within the 30-800 mm/s range without sensor lag.
Indexing Drum Loader
Indexes a multi-station machining drum, utilizing the equal extend and retract forces to maintain perfectly symmetrical acceleration profiles on both strokes.
Is the Airtac SED Double Rod Cylinder SED80X180 the Right Cylinder?
Selecting this 80 mm bore yields 2268 N both ways at 0.5 MPa (max 463 kgf at 1.0 MPa). If your payload is lighter, the adjacent 63 mm bore provides 1402 N both ways; for heavier drives, step up to the 100 mm bore, which outputs 3681 N both ways at 0.5 MPa. Choose this double-rod SED over a single-rod SE when the mechanism requires high torsional rigidity, anti-rotation stability, or synchronized actuation from both ends.
Remember that standard pneumatic pressure does not hold position on air loss—the piston will drift. For fail-safe holding, use a BSED double-rod lock or an external pilot-operated check valve. When replacing an existing ISO 15552 unit, match the 180 mm stroke, PT3/8 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2—this series omits FB, CA, CB, and CR).
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 SED80X180 FAQ
Because the 25 mm rod occupies 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 SED80X180 is dimensionally interchangeable per ISO 15552 / VDMA 24562 profile standards. Just match the PT3/8 port, M20x1.5 rod thread, and mounting interface (Basic, FA, LB, TC, FTC, TCM1, TCM2) for a drop-in replacement.
