Airtac SED Double Rod Cylinder SED100X180S
The AirTAC Airtac SED Double Rod Cylinder SED100X180S 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 180mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X180S
The AirTAC SED100X180S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 180mm stroke. Because a 25mm rod extends from 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. Equipped with a standard magnet (-S), it supports CMSE reed and DMSE electronic sensors for precise end-of-stroke detection.
This extruded aluminum profile cylinder omits external tie rods and includes field-adjustable air cushioning at both ends to decelerate heavy loads near stroke limits. The twin-rod architecture is highly effective against rotational torque, and the rear rod can drive a secondary mechanism or mount a cam. Remember to leave rear-rod clearance, as the overall length is longer than a single-rod SE cylinder.
Airtac SED Double Rod Cylinder SED100X180S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X180S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 180 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 SED100X180S Is Used
Servo Press Indexing
Drives a multi-station servo press stage requiring 5153 N of equal bidirectional force at 0.7 MPa, using the rear rod to mount a physical limit flag for the press confirmation sequence.
Pallet Transfer Pusher
Shifts heavy pallets on a packaging line, leveraging the twin rods to prevent rotational binding on the pusher plate during 180mm extend and retract cycles.
Large Component Machining
Actuates a heavy machining fixture clamp, using the 25mm rods to securely guide the clamping arm and resist cutting tool vibrations with 751 kgf max force.
Is the Airtac SED Double Rod Cylinder SED100X180S the Right Cylinder?
Select this 100mm bore when an application requires substantial bidirectional power, offering 3681 N both ways at 0.5 MPa. If your load is lighter, the 80mm bore provides 2268 N, while stepping up to the 125mm bore yields 5734 N. The double-rod design is superior to a single-rod SE when you need rigid anti-rotation guidance or dual-side tooling. For this 180mm stroke, the 25mm twin rods provide excellent side-load resistance, though external guides are recommended for heavy offset loads.
As a true ISO 15552 cylinder, it serves as a drop-in dimensional replacement matching the 100mm bore, 180mm stroke, PT1/2 port, and -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that a plain SED does not hold position on air loss; for fail-safe holding, consider a BSED double-rod rod lock or an external pilot-operated check valve.
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 SED100X180S FAQ
Because the double-rod design occupies piston 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 a true ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders. Just match the 100mm bore, 180mm stroke, PT1/2 port, and mounting style.
