Airtac SED Double Rod Cylinder SED80X155S
The AirTAC Airtac SED Double Rod Cylinder SED80X155S 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 155mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X155S
The AirTAC SED80X155S is a double-acting, double-rod ISO 15552 profile cylinder. A 25mm rod exits both end covers, yielding identical annulus areas. This means you get 2268 N of output force in both extend and retract directions at 0.5 MPa. The extruded aluminum barrel omits external tie rods for a clean ISO 15552 footprint.
Equipped with a magnetic piston (-S), it supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. The rear rod extension is ideal for mounting a secondary cam, driving a remote mechanism, or guiding the load against rotation. Field-adjustable air cushions at both ends decelerate the 30-800 mm/s travel speed smoothly.
Airtac SED Double Rod Cylinder SED80X155S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED80X155S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 155 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 SED80X155S Is Used
Servo-Driven Press
Provides 2268 N of equal bidirectional force at 0.5 MPa for precision stamping, using the rear rod to mount a mechanical cam for secondary ejection.
Pallet Transfer
Drives a dual-sided pusher arm at 30-800 mm/s, ensuring the load remains parallel and resists rotational twisting during high-speed transit.
Textile Calendering
Applies uniform 3175 N clamping pressure at 0.7 MPa on both extend and retract strokes to maintain consistent tension across fabric webs.
Is the Airtac SED Double Rod Cylinder SED80X155S the Right Cylinder?
When sizing this 80mm bore, compare its 2268 N both-way force at 0.5 MPa against its neighbors. Stepping down to a 63mm bore drops the output to 1402 N, while moving up to a 100mm bore increases it to 3681 N. Choose this double-rod SED over a single-rod SE when your application demands equal push/pull forces, superior anti-rotation stability, or rear-rod tooling. For a true ISO 15552 replacement, match the 80mm bore, 155mm stroke, PT3/8 port, and -S magnet. Note that air cushions only decelerate near stroke end; they do not hold position on air loss. For fail-safe holding, use a BSED double-rod lock or external rod lock.
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 SED80X155S FAQ
Because the double-rod design creates equal effective piston areas, output force is identical in both directions: 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and a maximum of 463 kgf at 1.0 MPa.
Yes. The SED80X155S is dimensionally interchangeable per ISO 15552. Match the 80mm bore, 155mm stroke, PT3/8 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note the overall length is longer than a single-rod SE to accommodate the rear rod.
