Airtac SED Double Rod Cylinder SED63X65S
The AirTAC Airtac SED Double Rod Cylinder SED63X65S 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 SED63X65S
The AirTAC SED63X65S is a double-acting, double-rod ISO 15552 profile cylinder. A 20mm rod exits both end covers, ensuring the effective area is identical on extend and retract. This design yields exactly 1402 N of force in both directions at 0.5 MPa.
Because the rear rod protrudes from the back cover, you can mount a cam or sensor flag to trigger DMSE electronic switches. The integrated -S magnet enables position feedback, while the extruded aluminum barrel maintains a true ISO 15552 mounting interface without external tie rods.
Airtac SED Double Rod Cylinder SED63X65S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED63X65S |
|---|---|
| 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 SED63X65S Is Used
Web Guiding Mechanism
Uses the 1402 N equal both-way force to tension and steer material rolls without rotational drift.
Dual-Station Shuttle
Transfers parts between two stations using both rod ends, leveraging the 36mm cushion to stop smoothly.
Centering Jig
Squeezes workpieces equally from both sides, relying on the M16x1.5 rod threads for custom tooling.
Is the Airtac SED Double Rod Cylinder SED63X65S the Right Cylinder?
Stepping down to the 50mm bore yields 825 N at 0.5 MPa, while stepping up to the 80mm bore provides 2268 N both ways. Choose this 63mm bore when your mechanism needs balanced push-pull dynamics and anti-rotation guidance that a single-rod SE cannot provide. To replace an ISO 15552 unit, match the 65mm stroke, PT3/8 port, and mounting type (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that a plain SED drifts on air loss; use a BSED double-rod lock for fail-safe holding.
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 SED63X65S FAQ
Because the rod occupies both piston sides, force is equal 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 the rear rod to drive a secondary mechanism or sensor cam. It also ensures push and pull speeds remain identical.
