Airtac SED Double Rod Cylinder SED63X280
The AirTAC Airtac SED Double Rod Cylinder SED63X280 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 280mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X280
The AirTAC SED63X280 is a double-acting, double-rod profile cylinder built to ISO 15552 dimensions. A 20mm rod exits both ends of the extruded aluminum barrel, yielding equal effective area on both piston sides. This generates 1402 N of output force in both extend and retract directions at 0.5 MPa. The PT3/8 port and 36mm adjustable air cushions manage smooth end-of-stroke deceleration.
Because a rod protrudes from the rear cover, you can mount a cam or sensor flag on the opposite end to trigger external logic. This SKU omits the magnet option, so it carries no internal position sensor. The twin-rod architecture also provides superior anti-rotation resistance compared to a single-rod SE cylinder.
Airtac SED Double Rod Cylinder SED63X280 Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 280 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 SED63X280 Is Used
Web Edge Guiding
Drives opposing guide rollers on a film or foil slitter. The 1402 N both-way force keeps the web centered, while the rear rod links to an external encoder flag.
Dual-Side Transfer
Pushes a 280mm stroke transfer carriage from both ends simultaneously on a packaging line, preventing skewing that a single-rod cylinder would cause.
Lifting Fork Assembly
Raises and lowers a precision machining sub-assembly. The twin 20mm rods resist torsional twist during heavy vertical lifts, ensuring parallel movement.
Is the Airtac SED Double Rod Cylinder SED63X280 the Right Cylinder?
At 0.5 MPa, this 63mm bore generates 1402 N both ways. If your payload is lighter, step down to the 50mm bore (825 N). If you need more thrust, step up to the 80mm bore (2268 N). Choose this double-rod SED over a single-rod SE when you need to drive two mechanisms in parallel, attach rear tooling, or prevent the load from twisting.
With a 280mm stroke, the extended rod length amplifies lateral leverage. Use external guide rails to prevent side loads from damaging the M16x1.5 rod threads or front cover. Note that a plain SED does not hold position on air loss; the piston drifts. For fail-safe holding, use a BSED double-rod rod lock or external pilot check valve. To replace an ISO 15552 unit, match the 63mm bore, 280mm stroke, PT3/8 port, 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 SED63X280 FAQ
Because the double-rod design has equal piston area 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. A plain SED cylinder will drift if air pressure is lost. The adjustable air cushions only decelerate the piston near the stroke ends; they do not lock the rod. For fail-safe holding, consider an AirTAC BSED rod-lock cylinder or an external pilot-operated check valve.
