Airtac SED Double Rod Cylinder SED80X65S
The AirTAC Airtac SED Double Rod Cylinder SED80X65S 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 65mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X65S
The AirTAC SED80X65S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. It features a 80mm bore, 65mm stroke, and a built-in magnet for position sensing. Because a 25mm rod exits both end covers, the effective piston area is identical on extend and retract, yielding an equal 2268N of thrust in both directions at 0.5 MPa.
This through-rod design allows the rear rod end to drive a secondary mechanism or mount a DMSE electronic sensor flag. The extruded aluminum barrel incorporates adjustable air cushions at both ends to decelerate loads near stroke end. It operates at 30-800 mm/s and uses a PT3/8 port.
Airtac SED Double Rod Cylinder SED80X65S Technical Specifications

| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 65 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 SED80X65S Is Used
Web Edge Guiding
Uses the 2268N equal both-way force to steer and align continuous material webs, leveraging the twin rods for high anti-rotation stability.
Shuttle Transfer
Drives a 65mm stroke parts shuttle between two stations, using the rear rod end to mount a secondary cam or limit flag for sequencing.
Multi-Action Press
Applies 3175N of clamping force at 0.7MPa while the opposing rod simultaneously ejects a finished part from the opposite side.
Is the Airtac SED Double Rod Cylinder SED80X65S the Right Cylinder?
Select this 80mm bore when an application requires 2268N of equal both-way force at 0.5 MPa (3175N at 0.7MPa). If you need less power, the 63mm bore provides 1402N both ways; if you need more, the 100mm bore offers 3681N. Choose this SED double-rod over a single-rod SE when you need rear-rod tooling, dual-side guidance, or enhanced anti-rotation stability. The integrated -S magnet supports CMSE reed and DMSE electronic sensors for end-of-stroke confirmation.
As a true ISO 15552 cylinder, it drops in dimensionally for any standard ISO 15552 double-rod footprint using Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts (omitting FB, CA, CB, CR). Note that air cushions only decelerate the load; they do not hold position on air loss. 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 SED80X65S FAQ
The SED80X65S provides equal force in both directions because a rod exits both ends. It delivers 2268N at 0.5MPa, 3175N at 0.7MPa, and a maximum of 463kgf at 1.0MPa.
A double-rod cylinder provides equal extend and retract forces, better load guidance against rotation, and a rear rod end for mounting secondary tooling or sensors. It is dimensionally interchangeable per ISO 15552 but omits FB, CA, CB, and CR rear mountings.
