Airtac SED Double Rod Cylinder SED63X240
The AirTAC SED Double Rod Cylinder SED63X240 is a genuine double-acting ISO 15552 double-rod cylinder: a Ø20mm piston rod exits BOTH ends of the Ø63mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 240mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X240
The AirTAC SED63X240 is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. A rod extends from both end covers, yielding identical annulus areas. It generates 1402 N of force in both directions at 0.5 MPa. The extruded aluminum barrel avoids external tie rods for a clean profile.
This 63 mm bore unit features a PT3/8 port, a 20 mm rod, and adjustable air cushions at both ends. Because this SKU lacks the -S magnet option, it does not support CMSE or DMSE position sensors. The rear rod extension can drive a secondary mechanism or mount a cam.
Airtac SED Double Rod Cylinder SED63X240 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED63X240 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 240 mm |
| Configuration | Double rod, double acting |
| Port size | PT3/8 |
| Rod thread | M16×1.5 |
| 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 (Ø63mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 1402 N |
| 0.7 MPa | 1962 N |
| Max (@1.0 MPa) | 286 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 SED63X240 Is Used
Web Guiding Mechanism
Drives a dual-sided aligner roller for film or foil lines. The twin rods prevent yaw while providing 1402 N of equal bidirectional force at 0.5 MPa.
Transfer Shuttle
Indexes parts between machining stations. The rear rod protrusion actuates a mechanical flag, sequencing the next station without external sensors.
Lifting Fork
Raises and lowers a precision machining sub-assembly. Equal force on extend and retract ensures smooth, balanced vertical motion.
Is the Airtac SED Double Rod Cylinder SED63X240 the Right Cylinder?
Choose this 63 mm bore to output 1402 N both ways at 0.5 MPa. If your load is lighter, step down to the 50 mm bore for 825 N; if heavier, step up to the 80 mm bore for 2268 N. The twin rods provide superior anti-rotation resistance compared to a single-rod SE cylinder. At 240 mm stroke, external guide rails are recommended to manage side loads. Note that a plain SED drifts on air loss; use a BSED or external lock for fail-safe holding. To replace an ISO 15552 unit, match the 240 mm stroke, PT3/8 port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, 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 SED63X240 FAQ
Because the double-rod design has equal piston areas on both sides, force is identical in both directions: 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa.
No. The adjustable air cushion only decelerates the piston near stroke end; it is not a brake. The cylinder will drift on air loss. For fail-safe holding, use a BSED double-rod rod lock cylinder or an external pilot-operated check valve.
