Airtac SED Double Rod Cylinder SED100X50
The AirTAC Airtac SED Double Rod Cylinder SED100X50 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 50mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X50
The AirTAC SED100X50 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100 mm bore and 50 mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding an equal 3681 N of thrust in both directions at 0.5 MPa. The extruded aluminum barrel omits external tie rods, ensuring a clean profile that drops in dimensionally for any ISO 15552 footprint.
This unit uses a PT1/2 port and a 25 mm rod with an M20x1.5 thread. It includes field-adjustable air cushioning at both ends to decelerate the load near stroke end. This specific SKU lacks a magnet, so it cannot host CMSE or DMSE position sensors without modification.
Airtac SED Double Rod Cylinder SED100X50 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X50 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 50 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 SED100X50 Is Used
Servo Press Platen
Drives a 100 mm press platen where the 3681 N equal both-way force ensures identical clamping and retraction pressure for stamping thin sheet metal.
Indexing Drum Gate
Actuates a heavy rotary drum gate, using the rear rod end to mount a cam while the twin rods resist torsional side load during rotation.
Mold Ejection Station
Ejects rubber molds on a conveyor, relying on the 751 kgf max output and adjustable cushions to smoothly decelerate the heavy 50 mm stroke.
Is the Airtac SED Double Rod Cylinder SED100X50 the Right Cylinder?
Select this 100 mm bore when an application requires substantial equal both-way force. Stepping down to the 80 mm bore drops the output to 2268 N at 0.5 MPa, while the larger 125 mm bore raises it to 5734 N. The twin-rod design is preferred over a single-rod SE when you need to mount rear-end tooling, drive a secondary mechanism, or prevent rotational drift. A plain SED does not hold position on air loss; for fail-safe locking, specify a BSED double-rod rod lock cylinder. To replace an existing ISO 15552 unit, verify the 50 mm 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 SED100X50 FAQ
Because the double-rod design has equal annulus areas on both sides, it outputs 3681 N at 0.5 MPa and 5153 N at 0.7 MPa in both directions. The maximum force is 751 kgf at 1.0 MPa.
The SED100X50 provides equal force and speed in both directions. The protruding rear rod allows you to mount a secondary cam or sensor flag, and the twin rods guide the load against rotation better than a single rod.
