Airtac SED Double Rod Cylinder SED80X95S
The AirTAC Airtac SED Double Rod Cylinder SED80X95S 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 95mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X95S
The AirTAC SED80X95S is a double-acting, double-rod profile cylinder built to the ISO 15552 interface. A Ø25 mm rod exits both end covers, yielding identical effective piston areas. This means you get equal thrust in extend and retract: 2268 N each way at 0.5 MPa. 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.
Because the rear rod protrudes through the back cover, you can mount a cam or sensor flag directly to it to trigger secondary events. The cylinder includes field-adjustable air cushions at both ends (36 mm cushion length) to decelerate loads near stroke end. Note that the overall length is longer than a single-rod SE cylinder, so you must leave clearance for the rear rod.
Airtac SED Double Rod Cylinder SED80X95S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED80X95S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 95 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 SED80X95S Is Used
Web Guiding Frames
Provides 2268 N of equal bidirectional force to steer heavy paper or film webs, using the rear rod to mount a dancer arm feedback cam.
Dual-Side Pallet Transfer
Drives opposing transfer arms simultaneously with 3175 N at 0.7 MPa, ensuring pallets stay square during high-speed lane shifts.
PCB Edge Trimming
The twin rods prevent chuck rotation during multi-axis trimming cuts, maintaining cutter precision across the 95 mm stroke.
Is the Airtac SED Double Rod Cylinder SED80X95S the Right Cylinder?
Stepping up from the 63 mm bore (1402 N at 0.5 MPa) to this 80 mm bore gives you 2268 N both ways at 0.5 MPa, while the next size up, the 100 mm, provides 3681 N. Choose this double-rod SED over a single-rod SE when your application requires anti-rotation guidance, the ability to drive twin loads, or rear-rod tooling. The PT3/8 port and M20x1.5 rod thread handle robust pneumatic flow and mounting. As a true ISO 15552 cylinder, it drops in for any standard double-rod footprint using Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts (omitting FB, CA, CB, CR). Remember, the air cushion only decelerates; it does not hold position on air loss. For fail-safe holding, use a BSED rod-lock cylinder or an external 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 SED80X95S FAQ
Because the double rods create equal annulus areas on both sides, 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.
The twin rods provide superior anti-rotation guidance and allow you to mount tooling, cams, or sensor flags on the rear rod end. It shares the exact ISO 15552 mounting interface but requires rear-rod clearance.
