Airtac SED Double Rod Cylinder SED63X65
The AirTAC SED Double Rod Cylinder SED63X65 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 65mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X65
The AirTAC SED63X65 is a double-acting, double-rod profile cylinder dimensionally interchangeable per ISO 15552. A 20mm rod exits both end covers, yielding identical annulus areas. This means the drive force is perfectly symmetrical, delivering 1402 N in both extend and retract directions at 0.5 MPa.
This specific SKU lacks the -S magnet option, so it has no internal position sensor. The extruded aluminum barrel includes adjustable air cushioning at both ends to decelerate the load near stroke limits. You can use the rear rod end to mount a cam or drive a secondary mechanism.
Airtac SED Double Rod Cylinder SED63X65 Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 65 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 SED63X65 Is Used
Web Guiding Mechanism
Drives a steering roller for film or paper webs. The twin rods prevent binding under offset loads, while the 1402 N both-way force ensures precise tension correction.
Dual-Side Transfer Gate
Shifts a transfer carriage between two packaging lanes. Equal extend and retract speed keeps cycle times predictable without needing flow controls.
Rear-Cam Actuation
Uses the protruding rear rod to trip a mechanical limit switch or secondary latch. The 65mm stroke provides compact motion without requiring extra sensor magnets.
Is the Airtac SED Double Rod Cylinder SED63X65 the Right Cylinder?
Choose this 63mm bore when you need 1402 N of both-way force at 0.5 MPa. If you need less force, step down to the 50mm bore (825 N). If your application requires more power, step up to the 80mm bore (2268 N). Compared to a single-rod SE cylinder, this SED twin-rod design provides superior anti-rotation guidance for the load and allows rear-rod tooling. The 65mm stroke is short, so side loading is minimal, but always keep the load guided. Note that a plain SED does not hold position on air loss; the piston drifts. For fail-safe holding, use a BSED double-rod lock cylinder or an external pilot-operated check valve. Replacement matching requires 63mm bore, 65mm stroke, PT3/8 port, and your mounting choice (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 SED63X65 FAQ
Because a rod exits both ends, the effective piston area is identical in both directions. The SED63X65 generates 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 the stroke ends; it is not a brake. If air loss occurs, the piston drifts. For fail-safe position holding, use an AirTAC BSED rod-lock cylinder or an external pilot-operated check valve.
