Airtac SED Double Rod Cylinder SED100X250
The AirTAC Airtac SED Double Rod Cylinder SED100X250 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 250mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X250
The AirTAC SED100X250 is a double-acting, double-rod ISO 15552 profile cylinder with a 250 mm stroke. Because a rod exits both end covers, the annulus area is identical on both sides, yielding equal force in extend and retract. You get 3681 N each way 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 dimensionally per ISO 15552.
This specific SKU lacks the -S magnet option, so it has no onboard position sensing. The rear rod extension can drive a secondary mechanism or mount a cam. Field-adjustable air cushioning at both ends decelerates the load near stroke limits over a 36 mm cushion length. Standard PT1/2 ports and an M20x1.5 rod thread handle high flow and heavy mounting.
Airtac SED Double Rod Cylinder SED100X250 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X250 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 250 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 SED100X250 Is Used
Servo Press Bonding
Drives an upper bonding head with 5153 N of equal both-way force at 0.7 MPa, using the rear rod to mount a mechanical cam for stroke confirmation.
Pallet Divert Arm
Actuates a heavy divert arm on a packaging conveyor, leveraging the twin rods to prevent rotational twist during high-speed 250 mm strokes.
Injection Mold Ejector
Ejects heavy injection molded parts symmetrically, using the balanced 3681 N both-way force at 0.5 MPa to push and pull the ejection plate.
Is the Airtac SED Double Rod Cylinder SED100X250 the Right Cylinder?
Choose this 100 mm bore when you need 3681 N of both-way thrust at 0.5 MPa. If you need less force, the 80 mm bore provides 2268 N both ways; if you need more, the 125 mm bore offers 5734 N. A double-rod design is preferred over a single-rod SE when the application demands anti-rotation stability, twin-side load guidance, or a rear rod to drive external tooling. At a 250 mm stroke, the protruding rear rod requires clearance and an external guide to manage side loads. This plain cylinder does not hold position on air loss; for fail-safe holding, use an external rod lock or a BSED series double-rod lock cylinder. ISO 15552 mounting interfaces include Basic, FA, LB, TC, FTC, TCM1, and 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 SED100X250 FAQ
The SED100X250 provides equal force in both directions due to the double-rod design. It outputs 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa.
Yes. The SED100X250 is an ISO 15552 profile cylinder with no external tie rods, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders. Just match the 100 mm bore, 250 mm stroke, PT1/2 ports, and mounting interface.
