Airtac SED Double Rod Cylinder SED100X290S
The AirTAC Airtac SED Double Rod Cylinder SED100X290S 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 290mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X290S
The AirTAC SED100X290S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 290mm stroke. A piston rod exits both end covers, yielding identical annulus areas that generate exactly 3681 N of force in both extend and retract directions at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, ensuring true ISO 15552 dimensional interchangeability.
Equipped with the -S magnet option, this unit supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. It features field-adjustable air cushioning at both ends and a PT1/2 port. The rear protruding rod is highly effective for mounting a secondary cam or driving a secondary mechanism, but requires dedicated clearance in your machine layout.

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 290 mm |
| Configuration | Double rod, double acting |
| Port size | PT1/2 |
| 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 |
| Max stroke | Up to 1500 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 SED100X290S Is Used
Servo Press Bed Leveling
Drives heavy stamping beds with 5153 N at 0.7 MPa, using the twin rods to prevent bed twisting under high off-center loads.
Pallet Transfer Pusher
Moves heavy pallets on a machining line; the rear rod simultaneously actuates a diverter cam, synchronizing dual mechanisms.
Sheet Metal Flattener
Applies equal 3681 N clamping force in both directions to press warped sheet metal flat without inducing rotational torque.
Is the Airtac SED Double Rod Cylinder SED100X290S the Right Cylinder?
Select this 100mm bore when your application requires substantial equal bidirectional force. If you need less power, the 80mm bore provides 2268 N at 0.5 MPa; if you require more, the 125mm bore offers 5734 N at 0.5 MPa. Because this unit has a 290mm stroke, external guide rails are recommended to prevent side loads from damaging the rod seals over extended travel. Unlike a single-rod SE cylinder, this double-rod design naturally resists mechanical rotation and can support loads on both ends. A plain SED does not hold position on air loss; the piston drifts and the air cushion only decelerates near stroke end. For fail-safe holding, use a BSED double-rod lock or an external pilot-operated check valve. To replace an existing ISO 15552 cylinder, match the 100mm bore, 290mm stroke, PT1/2 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 SED100X290S FAQ
Because a rod exits both ends, the effective piston area is identical on both sides. It delivers 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa in both extend and retract directions.
The twin rods provide superior anti-rotation guidance and allow the rear rod to drive a secondary mechanism or sensor flag. Remember to leave rear-rod clearance in your layout, as the overall length is longer than a single-rod cylinder.
