Airtac SED Double Rod Cylinder SED63X25S
The AirTAC SED Double Rod Cylinder SED63X25S 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 25mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X25S
The AirTAC SED63X25S is a double-acting, double-rod ISO 15552 profile cylinder. A 20mm rod exits both end covers, yielding identical annulus areas so thrust is exactly 1402N in extend and retract at 0.5 MPa. The integrated -S magnet supports CMSE reed and DMSE electronic sensors for dual-side position tracking.
Its extruded aluminum barrel lacks external tie rods, ensuring a clean ISO 15552 direct footprint. Adjustable air cushions at both ends decelerate the short 25mm stroke, while the protruding rear rod can mount a cam or secondary mechanism.
Airtac SED Double Rod Cylinder SED63X25S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED63X25S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 25 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 SED63X25S Is Used
Servo Press Dwell
Drives a short-stroke stamping head with 1402N of equal both-way force, using the rear rod to trip a proximity cam.
Web Edge Guide
Steers a paper web roller via twin rods that resist torsional twist, maintaining precise tracking without bind.
Diverter Gate
Flips a sorting flap with matched extend and retract speeds, ensuring stable actuation across the 25mm travel.
Is the Airtac SED Double Rod Cylinder SED63X25S the Right Cylinder?
Select this 63mm bore to generate 1402N both ways at 0.5 MPa. If your drive is underpowered, step down to the 50mm bore for 825N; if you need more push, step up to the 80mm bore for 2268N. Choose the SED double-rod over a single-rod SE when a rear-side flag, anti-rotation guidance, or identical push/pull force is required.
For position holding on air loss, note that a plain SED drifts; the cushions only decelerate near stroke end. Use a BSED double-rod lock for fail-safe hold. Replacement match: 63mm bore, 25mm stroke, PT3/8 port, M16x1.5 rod, and -S magnet.
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 SED63X25S FAQ
Because the double rods occupy both piston sides, force is equal in both directions: 1402N at 0.5 MPa, 1962N at 0.7 MPa, and a maximum of 286kgf at 1.0 MPa.
The twin rods provide anti-rotation guidance, allow rear-rod tooling or sensor flags, and ensure extend and retract speeds are identical. It shares the exact ISO 15552 mounting footprint of the SE series but omits FB, CA, CB, and CR mounts.
