Airtac SED Double Rod Cylinder SED80BX200S
The AirTAC Airtac SED Double Rod Cylinder SED80BX200S 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 200mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80BX200S
The AirTAC SED80BX200S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200 mm stroke and an 80 mm bore. Equipped with a SUS304 stainless steel rod, it is purpose-built for corrosive or washdown environments. Because a rod exits both end covers, the annular piston area is symmetrical, yielding identical output in both directions—generating 2268 N of force each way at 0.5 MPa.
This unit includes a standard magnet (-S) for position sensing via CMSE reed or DMSE electronic switches. The rear rod extension can drive a secondary mechanism or mount a cam, while simultaneously improving load guidance against rotation. Adjustable air cushions at both ends absorb end-of-stroke impact, though they do not hold position 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 |
| 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 SED80BX200S Is Used
Wafer Edge Grinding
The twin SUS304 rods provide anti-rotation guidance for precision grinders, ensuring the 3175 N both-way force holds the cutting head rigidly against the semiconductor wafer edge.
Dual-Side Conveyor Diverters
Drives opposing diverter arms simultaneously from one center mount. The 2268 N equal both-way force ensures balanced product routing without twisting the actuator.
Bottling Line Capping Heads
The rear rod end mounts a cam to trigger a capping torque mechanism, while the stainless construction survives harsh washdown cycles in beverage bottling plants.
Is the Airtac SED Double Rod Cylinder SED80BX200S the Right Cylinder?
Selecting this 80 mm bore makes sense when your process demands exactly 2268 N (at 0.5 MPa) or 3175 N (at 0.7 MPa) of symmetrical push and pull force. If your load is lighter, step down to the 63 mm bore, which provides 1402 N both ways; if heavier, the 100 mm bore offers 3681 N both ways. The SUS304 rod is essential for food-grade or chemical washdowns. Unlike a single-rod SE cylinder, this double-rod design prevents torsional twist on the load. For fail-safe holding during air loss, pair this cylinder with a BSED rod lock or external pilot check valve, as the air cushions only decelerate motion. At 200 mm stroke, external guides help manage any side-load moments.
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 SED80BX200S FAQ
Because the double-rod design balances the piston area, it generates equal force 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 SED80BX200S is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders. Just match the 80 mm bore, 200 mm stroke, PT3/8 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
