Airtac SED Double Rod Cylinder SED100X475
The AirTAC Airtac SED Double Rod Cylinder SED100X475 is a genuine double-acting ISO 15552 double-rod cylinder: a Ø25mm piston rod exits BOTH ends of the Ø100mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 475mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X475
The AirTAC SED100X475 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100 mm bore and 475 mm stroke. Because a Ø25 mm rod extends from both end covers, the annulus area is identical on extend and retract. This yields equal force in both directions, delivering 3681 N at 0.5 MPa and 5153 N at 0.7 MPa. The extruded aluminum barrel contains no external tie rods, ensuring a clean profile that drops in for any ISO 15552 dimensional replacement.
This unit lacks the -S magnet option, so it has no built-in position sensing. The rear rod protrusion allows you to mount a mechanical cam or secondary tooling opposite the primary work point. Field-adjustable air cushions at both ends safely decelerate the 30-800 mm/s motion near stroke end.

| 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 (Ø100mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 3682 N |
| 0.7 MPa | 5154 N |
| Max (@1.0 MPa) | 751 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 SED100X475 Is Used
Servo Press Feeders
Drives material into a servo press with 5153 N of equal bidirectional force, using the rear rod to trip a mechanical limit cam.
Pallet Diverters
Pushes heavy pallets laterally on a conveyor line, relying on the twin rods to prevent binding under offset loads.
Indexing Gate Actuators
Opens and closes heavy machine safety gates, maintaining consistent 3681 N force at 0.5 MPa throughout the extend and retract cycles.
Is the Airtac SED Double Rod Cylinder SED100X475 the Right Cylinder?
At 0.5 MPa, this 100 mm bore generates 3681 N of thrust both ways. If your payload is lighter, the 80 mm bore provides 2268 N and saves space. For heavier dynamics, stepping up to the 125 mm bore yields 5734 N. Choose this double-rod SED over a single-rod SE when your mechanism requires high resistance to torsional rotation or needs to drive a rear-mounted flag and cam. For a 475 mm stroke, external guide rails are recommended to prevent side-load deflection on the twin rods. Remember that the adjustable air cushion only decelerates the load; it does not hold position on air loss. For fail-safe holding, use an external rod lock or pilot-operated check valve. Match your replacement by verifying the PT1/2 port, M20x1.5 rod thread, and mounting subset (Basic, FA, LB, TC, FTC, TCM1, 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 SED100X475 FAQ
Because the double-rod design subtracts the rod area on both sides, force is identical in both directions. It delivers 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa.
The twin-rod configuration provides superior resistance to rotation and allows you to mount rear-side tooling or a cam. It is dimensionally interchangeable per ISO 15552, but note that overall length is longer to accommodate the rear rod.
