Airtac SED Double Rod Cylinder SED80BX175S
The AirTAC Airtac SED Double Rod Cylinder SED80BX175S 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 175mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80BX175S
The AirTAC SED80BX175S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensions. A SUS304 stainless steel rod extends from both end covers, yielding identical annulus areas. This means you get exactly 2268 N of output force at 0.5 MPa in both extend and retract directions.
The twin-rod architecture provides superior anti-rotation stability and allows the rear rod end to drive a secondary mechanism or mount a DMSE electronic sensor flag. It features field-adjustable air cushioning at both ends over a 36 mm stroke length and operates at speeds from 30-800 mm/s via PT3/8 ports.
Airtac SED Double Rod Cylinder SED80BX175S Technical Specifications

| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 175 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 SED80BX175S Is Used
Wafer Handling Ejectors
Drives dual-sided ejection pins in semiconductor wafer processing. The 2268 N equal both-way force ensures positive part release, while the SUS304 rod withstands cleanroom chemical washdowns.
Packaging Sync Transfer
Powers a synchronized push-pull transfer arm in food packaging lines. The twin rod prevents rotational drift during high-speed 30-800 mm/s cycling, keeping product alignment perfect.
Bottling Line Diverters
Actuates a diverter gate in beverage bottling. The rear rod end simultaneously triggers a DMSE electronic sensor flag, confirming gate position while the front rod handles the 2268 N load.
Is the Airtac SED Double Rod Cylinder SED80BX175S the Right Cylinder?
Choose this 80 mm bore when you need 2268 N both-way force at 0.5 MPa. If your load is lighter, the 63 mm bore offers 1402 N; if heavier, step up to the 100 mm bore providing 3681 N. The SUS304 rod is specifically sized for washdown or corrosive environments where carbon steel fails. Because the 175 mm stroke is under 300 mm, side-load stress is moderate, but external guides remain recommended for heavy lateral loads. This SED does not hold position on air loss; for fail-safe holding, use a BSED double-rod rod lock cylinder. To match this ISO 15552 replacement, verify the 80 mm bore, 175 mm stroke, PT3/8 port, and -S magnet requirement.
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 SED80BX175S FAQ
Because the rod exits both ends, the force is identical 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.
A double-rod SED provides equal force and speed in both directions, superior anti-rotation stability for heavy loads, and a rear rod end for mounting a sensor flag or driving a secondary mechanism. It is dimensionally interchangeable per ISO 15552.
