Airtac SED Double Rod Cylinder SED80X90S
The AirTAC Airtac SED Double Rod Cylinder SED80X90S 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 90mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X90S
The AirTAC SED80X90S is a double-acting, double-rod ISO 15552 profile cylinder offering 2268 N of force in both directions at 0.5 MPa. Because a 25mm rod exits both ends of the piston, the annular area is identical on extend and retract, yielding perfectly symmetrical thrust. The extruded aluminum barrel includes integrated sensor grooves, and this -S variant includes a magnet for position detection.
This through-rod design provides superior anti-rotation guidance and allows the rear rod to drive a secondary mechanism or mount a cam. Field-adjustable air cushions at both ends decelerate the load near stroke end, while the PT3/8 ports handle the required airflow. Remember that the adjustable cushion only absorbs end-of-stroke impact; it will not hold the load in place if air pressure drops.

| 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 SED80X90S Is Used
Web Guiding Mechanism
Drives a 2268 N equal-force correction roller on both extend and retract strokes, preventing web drift in film processing.
Dual-Side Lift Gate
Uses the through-rod to lift a 90mm stroke gate from both ends simultaneously, ensuring parallel movement without skewing.
Pneumatic Press Cam
Actuates a stamping cam where the rear rod end carries a limit flag to trigger the next machine cycle at 3175 N.
Is the Airtac SED Double Rod Cylinder SED80X90S the Right Cylinder?
At 0.5 MPa, this 80mm bore generates 2268 N each way. If your application requires less force, the 63mm bore provides 1402 N both ways. If you need more thrust, the 100mm bore offers 3681 N both ways. The twin-rod architecture is preferred over a single-rod SE when you need to mount tooling on both sides or require high resistance to torsional deflection. To replace an existing ISO 15552 unit, match the 90mm stroke, PT3/8 port, and mounting style (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 SED80X90S FAQ
The SED80X90S provides equal force in both directions due to the twin rods: 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and a maximum of 463 kgf at 1.0 MPa.
The SED80X90S uses a rod exiting both ends, which balances thrust on extend and retract, improves load guidance against rotation, and allows you to mount a sensor flag or secondary tooling on the rear rod.
