Airtac SED Double Rod Cylinder SED63X240S
The AirTAC SED Double Rod Cylinder SED63X240S 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 SED63X240S
The AirTAC SED63X240S is a double-acting, double-rod ISO 15552 profile cylinder. A 20 mm rod exits both end covers, yielding identical annulus areas. It delivers an equal 1402 N of force in both extend and retract directions at 0.5 MPa.
Because a rod protrudes from the rear, you can mount a cam or DMSE electronic sensor flag directly opposite the primary work tool. The extruded aluminum barrel includes adjustable air cushions at both ends to decelerate the 240 mm stroke, and the -S magnet enables position detection.
Airtac SED Double Rod Cylinder SED63X240S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED63X240S |
|---|---|
| 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 SED63X240S Is Used
Multi-Station Machining
Drives a multi-station machining fixture using the front rod for clamping and the rear rod to actuate a synchronized part ejector, relying on the 1402 N both-way force.
Reciprocal Transfer
Powers a reciprocal conveyor diverter where the twin rods prevent binding under offset loads, maintaining smooth 240 mm transitions without twisting.
Web Tensioning
Actuates a web tensioning dancer roll in a packaging line, using the equal extend and retract forces to maintain consistent material tension bidirectionally.
Is the Airtac SED Double Rod Cylinder SED63X240S the Right Cylinder?
At 0.5 MPa, this 63 mm bore generates 1402 N each way. If your drive needs less force, step down to the 50 mm bore (825 N both ways); if you need more, step up to the 80 mm bore (2268 N both ways). Choose this double-rod SED over a single-rod SE when you need superior anti-rotation guidance or must drive a secondary mechanism from the rear rod.
For direct replacements, match the 63 mm bore, 240 mm stroke, PT3/8 port, and your mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that a plain SED drifts on air loss; for fail-safe holding, use a BSED double-rod lock. At 240 mm stroke, external guides are recommended to manage side loads.
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 SED63X240S FAQ
Because the double-rod design creates 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.
The twin-rod design provides superior anti-rotation guidance and allows you to mount a rear cam or sensor flag. It is dimensionally interchangeable per ISO 15552, using a profile barrel without external tie rods.
