Airtac SED Double Rod Cylinder SED80X1000S
The AirTAC Airtac SED Double Rod Cylinder SED80X1000S 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 1000mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X1000S
The AirTAC SED80X1000S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a 25mm rod exits both ends, the effective piston area is identical in both directions, yielding an equal 2268 N of force at 0.5 MPa on extend and retract. The extruded aluminum barrel has no external tie rods, and the -S option equips the piston with a magnet for CMSE reed or DMSE electronic sensors.
This 1000mm stroke unit features field-adjustable air cushioning at both ends (36mm cushion length) to decelerate heavy loads near stroke end. Remember that the twin-rod design increases the overall length; you must leave rear-rod clearance for the protruding M20x1.5 thread. The cushion only slows the piston near the end of travel—it does not lock or hold the load in place on air loss.

| 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 SED80X1000S Is Used
Long-Stroke Transfer Conveyor
Drives a 1000mm transfer carriage with 2268N of equal both-way force, using the rear rod to mount a tracking flag for DMSE sensors.
Multi-Station Indexing Gate
Actuates a heavy gating mechanism where the twin 25mm rods prevent binding across the long 1-meter travel, ensuring smooth part routing.
Rear-Mounted Cam Ejector
Uses the protruding rear rod end to physically trip a sequence valve cam while the front rod pushes parts with 3175N at 0.7 MPa.
Is the Airtac SED Double Rod Cylinder SED80X1000S the Right Cylinder?
Select this 80mm bore when your mechanism requires exactly 2268 N of both-way force at 0.5 MPa (3175 N at 0.7 MPa). If you need less force, stepping down to the 63mm bore provides 1402 N both ways; if your load is heavier, stepping up to the 100mm bore provides 3681 N both ways. The double-rod design is preferred over a single-rod SE when you need superior anti-rotation guidance, rear-rod tooling mounts, or a cam for dual-side limit switches.
At 1000mm stroke, the extended rod is highly susceptible to side loads and bending—always use external guide rails to support the load and prevent cylinder damage. For a drop-in ISO 15552 replacement, match the 80mm bore, 1000mm stroke, PT3/8 port, and your mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that a plain SED drifts on air loss; for fail-safe holding, specify a BSED double-rod 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 SED80X1000S FAQ
Because the 25mm rod occupies both sides of the piston, force is equal 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.
The twin rods provide superior load guidance and prevent rotation across the long 1000mm stroke. The rear rod also allows you to mount a cam or sensor flag, making it ideal for sequencing without adding external track mechanisms.
