Airtac SED Double Rod Cylinder SED63X80
The AirTAC Airtac SED Double Rod Cylinder SED63X80 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 80mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X80
The AirTAC SED63X80 is a double-acting, double-rod ISO 15552 profile cylinder with an 80mm stroke. Because a 20mm rod occupies both piston sides, effective areas match, yielding equal extend and retract forces of 1402N at 0.5MPa. Its extruded aluminum barrel omits external tie rods.
This unit lacks the -S magnet option, meaning no CMSE or DMSE position sensing is installed. The rear protruding rod can drive a secondary mechanism or mount a cam, while adjustable air cushions at both ends decelerate motion near stroke limits.
Airtac SED Double Rod Cylinder SED63X80 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED63X80 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 80 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 SED63X80 Is Used
CNC Lathe Bar Feeder
Pushes raw bar stock through a spindle with its front rod while the rear rod simultaneously advances a limit flag, utilizing the 1402N both-way force for consistent feed and retraction.
Package Flap Tucking
Drives a carton sealing mechanism where the twin 20mm rods prevent wobble during high-speed 30-800 mm/s travel, ensuring precise flap placement under 1962N at 0.7MPa.
Dual-Side Gripper Transfer
Actuates a transfer arm that grips parts on one end while the opposing rod mirrors the motion for a secondary tool, relying on equal bidirectional thrust for balanced cycling.
Is the Airtac SED Double Rod Cylinder SED63X80 the Right Cylinder?
Stepping down to the 50mm bore yields 825N both ways at 0.5MPa, while the larger 80mm bore provides 2268N. Choose this 63mm model when your mechanism needs balanced 1402N thrust alongside twin-rod anti-rotation stability. It uses a PT3/8 port and M16x1.5 rod thread.
To replace an ISO 15552 cylinder, match the 63mm bore, 80mm stroke, and mounting style (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 or external brake.
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 SED63X80 FAQ
Because the double-rod design equalizes piston area, it provides 1402N at 0.5MPa, 1962N at 0.7MPa, and a maximum of 286kgf at 1.0MPa in both extend and retract directions.
Yes, it is dimensionally interchangeable per ISO 15552 / VDMA 24562. Just match the 63mm bore, 80mm stroke, PT3/8 port, and mounting interface, but ensure you leave rear-rod clearance since a rod exits both ends.
