Airtac SED Double Rod Cylinder SED40X30S
The AirTAC Airtac SED Double Rod Cylinder SED40X30S 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 30mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED40X30S
The AirTAC SED40X30S is a double-acting, double-rod ISO 15552 profile cylinder. Because a 16 mm rod occupies both piston sides, the annulus area is identical in both directions, yielding an equal 528 N of force at 0.5 MPa on extend and retract. The extruded aluminum barrel contains no external tie rods, ensuring a clean ISO 15552 footprint.
Equipped with the -S magnet option, this 40 mm bore unit integrates seamlessly with CMSE reed and DMSE electronic sensors. The protruding rear rod provides dual-side guidance, resisting rotation better than a single-rod SE cylinder while offering a mounting point for a secondary cam or mechanism.

| 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 SED40X30S Is Used
Servo-Driven Press
Provides 528 N of equal bidirectional force at 0.5 MPa for precision stamping, using the rear rod to mount a mechanical stroke-position flag.
Pneumatic Divertor
Drives a 30 mm conveyor sorting flap with equal speed both ways, leveraging the twin rods to prevent binding during rapid direction changes.
PCB Shuttle
Indexes a circuit board carrier over a short 30 mm path, using DMSE electronic sensors to track the extending and retracting rod ends.
Is the Airtac SED Double Rod Cylinder SED40X30S the Right Cylinder?
Select the SED40X30S when your mechanism requires equal push and pull forces, such as 528 N at 0.5 MPa. If you need less force, the 32 mm bore provides 345 N both ways; if your load demands more, step up to the 50 mm bore for 825 N. The 30 mm stroke keeps overall length compact, minimizing side-load leverage on the 16 mm rod.
Unlike a single-rod SE cylinder, this double-rod design supports rear-end tooling and anti-rotation guidance. Remember that a plain SED does not hold position on air loss—the piston drifts. For fail-safe holding, consider a BSED double-rod lock or an external pilot-operated check valve. Replacement matches require the 40 mm bore, 30 mm stroke, PT1/4 port, and an -S magnet.
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 SED40X30S FAQ
The double-rod design yields equal force in both directions: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa.
A rod exits both ends, creating identical extend and retract speeds while providing dual-side load guidance. The rear rod also serves as a mounting point for cams or CMSE/DMSE sensor flags.
