Airtac SED Double Rod Cylinder SED100X350
The AirTAC Airtac SED Double Rod Cylinder SED100X350 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 350mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X350
The AirTAC SED100X350 is a double-acting, double-rod ISO 15552 profile cylinder with a 100 mm bore and 350 mm stroke. Because a rod exits both end covers, the effective piston area is identical on extend and retract, yielding an equal force of 3681 N each way at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, ensuring a clean profile that drops directly into standard ISO 15552 mounting interfaces.
This unit features field-adjustable air cushioning at both ends to decelerate the load near stroke extremes, though it is not a locking brake. The rear rod extension can drive a secondary mechanism or mount a cam. This specific SKU lacks a magnet, meaning no CMSE or DMSE position sensors can be fitted without modifying the piston.

| 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 |

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 SED100X350 Is Used
CNC Pallet Changer
Indexes heavy machining pallets with 5153 N of equal both-way force at 0.7 MPa, using the rear rod to trip a limit switch.
Panel Straightener
Presses sheet metal panels flat using twin rods that prevent wrenching, delivering 751 kgf max force without rotational drift.
Transfer Shuttle
Shuttles automotive parts between stations, relying on the ISO 15552 footprint and 350 mm stroke to push and pull equal payloads.
Is the Airtac SED Double Rod Cylinder SED100X350 the Right Cylinder?
Selecting this 100 mm bore provides 3681 N of equal both-way force at 0.5 MPa. If your application requires less force, stepping down to the 80 mm bore yields 2268 N both ways at 0.5 MPa. If you need more power, moving up to the 125 mm bore provides 5734 N both ways at 0.5 MPa. The twin-rod design is preferred over a single-rod SE cylinder when you need anti-rotation stability or must drive a load from both ends simultaneously.
A plain SED does not hold position on air loss; the piston will drift, so for fail-safe holding you need a BSED double-rod rod lock or an external pilot-operated check valve. At 350 mm of stroke, the protruding rear rod requires substantial clearance, and you must account for potential side loads by adding external guide rails to prevent premature seal wear. Replacement matching requires a 100 mm bore, 350 mm stroke, PT1/2 port, and a compatible mounting subset such as FA, LB, or TC.
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 SED100X350 FAQ
Because the double-rod design subtracts the rod area on both sides, force is equal in both directions: 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. Just match the 100 mm bore, 350 mm stroke, PT1/2 port, and choose from the available mounting options like FA, LB, TC, FTC, TCM1, or TCM2.
