Airtac SED Double Rod Cylinder SED100X350S
The AirTAC Airtac SED Double Rod Cylinder SED100X350S 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 SED100X350S
The AirTAC SED100X350S is a double-acting, double-rod ISO 15552 profile cylinder. A 25 mm rod exits both end covers, yielding identical annulus areas. This guarantees equal force in extend and retract, delivering 3681 N each way at 0.5 MPa and 5153 N at 0.7 MPa. The standard -S magnet supports DMSE electronic and CMSE reed sensors for end-of-stroke confirmation.
Because a rod protrudes from the rear, you gain a secondary attachment point for a cam or limit flag while improving load guidance against rotation. The extruded aluminum barrel omits external tie rods. Field-adjustable air cushions at both ends decelerate the 30-800 mm/s motion over a 36 mm stroke length.

| Stroke | 350 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 SED100X350S Is Used
Large-Panel Edge Guiding
Uses the 5153 N both-way thrust to clamp and guide heavy sheet metal panels through a multi-station stamping line, relying on the twin rods to prevent rotational deflection.
Pallet Transfer Pusher
Drives a 350 mm transfer carriage for heavy pallets, using the rear rod end to mount a physical cam that triggers a mechanical diverter upon full extension.
Tandem Press Feed Actuator
Provides 3681 N of equal bidirectional force to position a heavy feed roll carriage, ensuring the material strip advances and retracts with precise symmetry.
Is the Airtac SED Double Rod Cylinder SED100X350S the Right Cylinder?
Select this 100 mm bore when you need 5153 N of both-way thrust at 0.7 MPa. Stepping down to the 80 mm bore drops the both-way force to 2268 N at 0.5 MPa, while stepping up to the 125 mm bore yields 5734 N at 0.5 MPa. Choose this double-rod SED over a single-rod SE when your mechanism requires twin-side load support or a rear-rod driven auxiliary function.
For drop-in ISO 15552 replacements, match the 350 mm stroke, PT1/2 port, and mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). At 350 mm stroke, external guide rails are strongly advised to prevent rod side-loading. Note that a plain SED drifts on air loss; the adjustable cushion only decelerates near stroke end and does not hold position. Use a BSED double-rod rod lock for fail-safe holding.
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 SED100X350S FAQ
Because the double-rod design creates equal annulus areas, force is identical 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.
A rod exits both ends, providing equal extend and retract forces and better resistance to load rotation. The rear rod also allows mounting a secondary cam or sensor flag. It drops into any ISO 15552 footprint using Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts.
