Airtac SED Double Rod Cylinder SED100X20
The AirTAC Airtac SED Double Rod Cylinder SED100X20 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 20mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X20
The AirTAC SED100X20 is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a 25 mm rod exits both end covers, the annulus area is identical on each side. This means you get exactly 3681 N of output force at 0.5 MPa in both extend and retract directions. The extruded aluminum barrel contains no external tie rods, ensuring a clean profile that drops in for any standard ISO 15552 footprint.
This 20 mm stroke unit uses PT1/2 ports and an M20x1.5 rod thread. A field-adjustable air cushion at both ends decelerates the load near stroke end. This SKU ships without a magnet, so it does not support CMSE or DMSE position sensing. The rear rod extension is perfect for mounting a cam or driving a secondary mechanism.
Airtac SED Double Rod Cylinder SED100X20 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X20 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 20 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 SED100X20 Is Used
Short-Stroke Staking Press
Provides a balanced 3681 N force at 0.5 MPa for staking metal assemblies, using the twin rods to keep the tooling perfectly aligned during the 20 mm impact.
Dual-Side Guiding Clamp
Clamps heavy workpieces with equal extend and retract power, leveraging the through-rod geometry to prevent jaw twisting under off-center loads.
Rear-Cam Actuation Station
Drives a primary forming operation while the protruding rear rod end simultaneously triggers a mechanical cam or limit flag for downstream sequencing.
Is the Airtac SED Double Rod Cylinder SED100X20 the Right Cylinder?
Choose this 100 mm bore when you need substantial equal both-way force (3681 N at 0.5 MPa). If your application requires less force, the neighboring 80 mm bore provides 2268 N at 0.5 MPa. If you need more power, the 125 mm bore offers 5734 N at 0.5 MPa. The twin-rod design provides superior anti-rotation stability compared to a single-rod SE cylinder, making it ideal for short-stroke pressing or clamping. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, CR). Note that a plain SED does not hold position on air loss; for fail-safe holding, use a BSED or an external rod lock.
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 SED100X20 FAQ
Because the double-rod design yields equal force both ways, this cylinder outputs 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per ISO 15552 profile standards. However, it is double-acting and will drift on air loss; you must add an external rod lock or use a BSED for fail-safe position holding.
