Airtac SED Double Rod Cylinder SED40X100S
The AirTAC Airtac SED Double Rod Cylinder SED40X100S 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 100mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED40X100S
The AirTAC SED40X100S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 100mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding a perfectly balanced 528 N output force at 0.5 MPa in either direction. The extruded aluminum barrel contains no external tie rods, ensuring a clean profile that drops in dimensionally for any ISO 15552 footprint.
Equipped with a standard magnet (-S), this unit supports electronic DMSE and reed CMSE position sensing. The 16mm rod uses an M12x1.25 thread, and field-adjustable air cushions at both ends provide precise deceleration near stroke extremes. Note that the twin-rod design makes the overall length longer than a single-rod SE, so plan for rear-rod clearance.

| 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 SED40X100S Is Used
Dual-Side Stamping Press
Drives a 528 N stamping tool from the front rod while the rear rod actuates a part ejection cam, utilizing the equal both-way force for synchronized motion.
Packaging Line Diverter
Pushes cartons at 30-800 mm/s using the front rod, while the rear rod mounts a DMSE sensor flag to confirm retract position without external brackets.
Wire Straightener Clamp
Secures wire during feeding with 739 N at 0.7 MPa, leveraging the twin-rod anti-rotation guidance to prevent jaw twisting during high-speed cuts.
Is the Airtac SED Double Rod Cylinder SED40X100S the Right Cylinder?
Select this 40mm bore if your application requires 528 N of bidirectional force at 0.5 MPa. If you need less push, the 32mm SED provides 345 N; if you need more, step up to the 50mm bore, which generates 825 N both ways. The double-rod architecture is preferred over single-rod SE cylinders when you need rear-rod tooling, a cam for a limit switch, or superior resistance to torsional side loads. For 100mm strokes, side loading is minimal, but external guides should still carry the primary load mass. Remember that a plain SED does not hold position on air loss—the piston will drift. For fail-safe holding, use a BSED double-rod lock or an external pilot-operated check valve. Match your replacement by verifying the 100mm stroke, PT1/4 port, and required 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 SED40X100S FAQ
Because the double-rod design subtracts the 16mm rod area from both sides, force is equal 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.
The twin rods provide equal extend/retract forces and better torsional stability. The rear rod can drive a secondary mechanism or sensor flag, and it drops in dimensionally for any ISO 15552 mounting interface.
