Airtac SED Double Rod Cylinder SED40X10S
The AirTAC Airtac SED Double Rod Cylinder SED40X10S is a genuine double-acting ISO 15552 double-rod cylinder: a Ø16mm piston rod exits BOTH ends of the Ø40mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 10mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED40X10S
The AirTAC SED40X10S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 10mm stroke. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding an equal force of 528 N each way at 0.5 MPa. The extruded aluminum barrel omits external tie rods, ensuring a clean profile that drops into standard ISO 15552 dimensional interfaces.
Equipped from the factory with a magnet (-S), this unit supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. The rear rod extension is perfect for mounting a cam or limit flag, while the twin-rod geometry inherently resists torsional rotation. Field-adjustable air cushions at both ends decelerate the payload smoothly near stroke end.

| Port size | PT1/4 |
| Rod thread | M12×1.25 |
| 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, 30 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 (Ø40mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 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 SED40X10S Is Used
Gripper Synchronization
Drives opposing gripper jaws in packaging machines, utilizing the 528 N equal both-way force to ensure perfectly synchronized clamping and release.
Short-Stroke Punching
Powers compact stamping stations in electronics assembly, where the twin rods prevent deflection and the rear rod actuates a limit flag.
Web Edge Guiding
Steers material webs in textile machinery, using the anti-rotation properties of the double rod to maintain precise alignment across the 10mm travel.
Is the Airtac SED Double Rod Cylinder SED40X10S the Right Cylinder?
Select this 40mm bore when you need 528 N of bidirectional force at 0.5 MPa. If your payload is lighter, step down to the 32mm bore providing 345 N; for heavier drives, step up to the 50mm bore offering 825 N. This SED40X10S includes a magnet for position sensing, uses a PT1/4 port, and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts (omitting FB/CA/CB/CR).
Choose the twin-rod SED over a single-rod SE when your mechanism requires dual-side guidance, anti-rotation stability, or rear-rod tooling. Note that a plain double-rod cylinder drifts on air loss; the adjustable cushion decelerates but does not lock. For fail-safe holding, use an external rod lock or BSED series. With a 10mm stroke, side loads are minimal, but external guides remain recommended for heavy lateral forces.
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 SED40X10S FAQ
The SED40X10S provides equal force in both directions due to the double-rod design. It outputs 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa.
The double-rod design provides equal extend and retract forces, better load guidance against rotation, and a rear rod that can drive a secondary mechanism or sensor cam. It is dimensionally interchangeable per ISO 15552.
