Airtac SED Double Rod Cylinder SED80X100
The AirTAC Airtac SED Double Rod Cylinder SED80X100 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 100mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X100
The AirTAC SED80X100 is a double-acting, double-rod profile cylinder built to the ISO 15552 interface. A 25mm rod exits both end covers, yielding an identical annulus area on each side. This means the drive force is perfectly symmetrical, outputting 2268 N in both extend and retract directions at 0.5 MPa.
It features a PT3/8 port, an M20x1.5 rod-end thread, and field-adjustable air cushioning at both ends. Because a rod protrudes from the rear cover, you must leave clearance for it, but this allows you to mount a cam or secondary mechanism on the back side. Note this SKU lacks a magnet, so it has no position sensing.
Airtac SED Double Rod Cylinder SED80X100 Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 100 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 SED80X100 Is Used
Web Guiding Mechanism
Drives a steering roller for film or foil webs. The twin rods prevent rotational twisting during high-speed corrections, utilizing the 2268 N both-way force to shift the guide evenly.
Multi-Station Indexer
Moves a dial table between machining stations. The rear rod end mounts a physical cam to trigger pneumatic valves, leveraging the equal push and pull dynamics at 0.7 MPa.
Dual-Side Transfer Pusher
Pushes pallets across a belt. The double-rod profile provides dual-side guidance for heavy pallets, ensuring stable transfer without binding across the 100mm stroke.
Is the Airtac SED Double Rod Cylinder SED80X100 the Right Cylinder?
Select this 80mm bore when you need 2268 N of both-way force at 0.5 MPa (or 3175 N at 0.7 MPa). If you need less force, the 63mm bore provides 1402 N at 0.5 MPa; if you need more, the 100mm bore provides 3681 N. The twin-rod design resists torsional rotation better than a single-rod SE cylinder, making it ideal for guiding heavy loads. Since this is a 100mm stroke, side-load is minimal, but always support the load externally. A plain SED does not hold position on air loss—the piston drifts. For fail-safe holding, use a BSED double-rod rod lock. To replace any ISO 15552 cylinder, match the 80mm bore, 100mm stroke, PT3/8 port, and mounting (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
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 SED80X100 FAQ
Because the double-rod design creates equal annulus areas on both sides, the 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 SED80X100 is dimensionally interchangeable per ISO 15552. Ensure you match the 80mm bore, 100mm stroke, PT3/8 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, TCM2). Remember to leave rear-rod clearance, as a rod exits both ends.
