Airtac SED Double Rod Cylinder SED100X290
The AirTAC Airtac SED Double Rod Cylinder SED100X290 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 SED100X290
The AirTAC SED100X290 is a double-acting, double-rod profile cylinder built to ISO 15552 dimensions. A Ø25mm rod exits both end covers, yielding an identical annulus area on each side. This means you get exactly 3681 N of output force at 0.5 MPa on both extend and retract strokes.
This unit lacks the standard magnet option (-S), so it does not support CMSE or DMSE position sensing out of the box. The extruded aluminum barrel incorporates adjustable air cushioning at both ends to tame kinetic energy near stroke limits. Because a rod protrudes from the rear, you must account for extra clearance to mount a cam or secondary tool.
Airtac SED Double Rod Cylinder SED100X290 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X290 |
|---|---|
| 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 SED100X290 Is Used
Servo Press Platen
Drives a 290mm stroke platen in an assembly press, utilizing the 3681 N both-way force to stamp and return components without rotational deflection.
Pallet Diverting Arm
Actuates a dual-sided diverting arm on a heavy-duty packaging line, using the rear rod end to mount a synchronized cam for a secondary gate.
Textile Calendering
Guides a calendering roller mechanism where equal push and pull forces are critical to maintaining consistent fabric tension across the 100mm bore.
Is the Airtac SED Double Rod Cylinder SED100X290 the Right Cylinder?
Choose this 100mm bore when you need 3681 N of bidirectional force at 0.5 MPa. Stepping down to the 80mm bore drops your output to 2268 N, while moving up to the 125mm bore raises it to 5734 N. The twin-rod design inherently resists torsional rotation better than a single-rod SE cylinder, making it ideal for lifting heavy parallel loads.
At 290mm of stroke, the extended rod length amplifies any side-load leverage. Use external guide rails to prevent binding and premature seal wear. Remember that a plain SED100X290 will drift if air pressure drops; the adjustable cushion only decelerates the piston near the end caps and does not lock position. For fail-safe holding, consider an external rod lock or the BSED series.
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 SED100X290 FAQ
Because the double-rod design occupies piston area on both sides, force is equal in both directions. It provides 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa.
Yes. The SED100X290 is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders. Just match the PT1/2 port, 290mm stroke, and your required mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
