Airtac SED Double Rod Cylinder SED100X185S
The AirTAC Airtac SED Double Rod Cylinder SED100X185S 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 185mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X185S
The AirTAC SED100X185S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensions. A Ø25 mm rod extends from both end covers, yielding identical annulus areas. This means you get exactly 3681 N of force in both extend and retract directions at 0.5 MPa.
Equipped with a -S magnet, the rear rod can trigger DMSE electronic or CMSE reed sensors for end-of-stroke confirmation. The extruded aluminum barrel omits external tie rods, and adjustable air cushions at both ends protect your mechanics from impact.
Airtac SED Double Rod Cylinder SED100X185S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X185S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 185 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 SED100X185S Is Used
Multi-Station Machining Clamp
Provides 5153 N of equal clamping force on both strokes, securing heavy cast iron engine blocks during CNC milling without rotational drift.
Pallet Transfer Diverter
Uses the rear rod end to push a diverter gate while the front rod cycles a pneumatic stop, synchronizing two packaging line actions at once.
Injection Mold Ejector
Drives dual ejector pins from both ends to strip large automotive plastic panels straight out of the mold, leveraging the anti-rotation properties.
Is the Airtac SED Double Rod Cylinder SED100X185S the Right Cylinder?
Choose this 100 mm bore when you need 5153 N (at 0.7 MPa) of equal both-way thrust. If your load is lighter, stepping down to the 80 mm bore provides 2268 N. For heavier drives, the 125 mm bore offers 5734 N. At 185 mm stroke, the 30-800 mm/s speed range is manageable, but always support the load externally to prevent rod binding.
A twin-rod design inherently resists rotation better than a single-rod SE cylinder, making it perfect for guided lifts. Note that air cushions only decelerate near stroke end; they do not hold position on air loss. For fail-safe holding, use a BSED double-rod lock or external check valve. To match an ISO 15552 replacement, verify the PT1/2 port, M20x1.5 thread, 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 SED100X185S FAQ
Because the double-rod design creates equal piston areas on both sides, 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.
Beyond dropping into any ISO 15552 footprint, the twin rods provide superior anti-rotation guidance. The protruding rear rod can also drive a secondary mechanism or mount a sensor flag, saving space.
