Airtac SED Double Rod Cylinder SED100X170S
The AirTAC Airtac SED Double Rod Cylinder SED100X170S 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 170mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X170S
The AirTAC SED100X170S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. It features an extruded aluminum barrel and a piston rod exiting both end covers, yielding identical effective areas. This equal-annulus design generates 3681 N of thrust and pull at 0.5 MPa, ensuring perfectly balanced motion in both directions.
Fitted standard with a magnetic piston (-S), this 100mm bore unit supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. The protruding rear rod is ideal for mounting secondary tooling, driving a cam, or pushing a secondary mechanism while significantly improving load stability and resisting rotation compared to a single-rod SE cylinder.
Airtac SED Double Rod Cylinder SED100X170S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X170S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 170 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 SED100X170S Is Used
CNC Lathe Bar Feeders
Drives bar stock pushers with 3681N of equal both-way force, using the rear rod to trigger a mechanical flag for synchronized material loading.
Pallet Transfer Stops
Halts heavy 100mm conveyor pallets reliably; the twin-rod design prevents binding under high side-loads while matching ISO 15552 machine footprints.
Automated Welding Clamps
Actuates 5153N welding clamps at 0.7MPa, utilizing the rear protruding rod to mount a secondary cam for part ejection.
Is the Airtac SED Double Rod Cylinder SED100X170S the Right Cylinder?
Choose this 100mm bore if your process requires exactly 3681 N (at 0.5 MPa) of balanced force in both directions. If your load is lighter, the 80mm bore offers 2268 N both ways; for heavier demands, the 125mm bore provides 5734 N both ways. The double-rod architecture is essential when you need anti-rotation guidance or a rear-rod connection for dual mechanisms. Remember that a plain SED does not hold position on air loss—the piston will drift. For fail-safe load holding, consider a BSED double-rod lock cylinder or an external pilot-operated check valve. When replacing an ISO 15552 unit, match the 100mm bore, 170mm 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 SED100X170S FAQ
Because the double-rod design has equal piston areas on both sides, the force is identical in extend and retract. It provides 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa.
The SED provides equal force and speed in both directions, better load stability against rotation, and a rear rod that can drive a secondary mechanism or sensor flag. It is dimensionally interchangeable with other ISO 15552 double-rod cylinders.
