Airtac SED Double Rod Cylinder SED63X90
The AirTAC Airtac SED Double Rod Cylinder SED63X90 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 90mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X90
The AirTAC SED63X90 is a double-acting, double-rod ISO 15552 profile cylinder offering true dimensional interchangeability for drop-in replacements. A 20 mm rod exits both end covers, yielding an identical annulus area on both sides of the piston. This geometry delivers equal force and speed in extend and retract, outputting exactly 1402 N each way at 0.5 MPa.
This 63 mm bore unit features a PT3/8 port, an M16x1.5 rod-end thread, and field-adjustable air cushioning at both ends to tame end-of-stroke impacts. This specific SKU lacks a magnet, meaning no CMSE or DMSE position sensing is possible without a different option code. The extruded aluminum barrel provides a rigid, tie-rod-free structure.
Airtac SED Double Rod Cylinder SED63X90 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED63X90 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 90 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 SED63X90 Is Used
Servo-Driven Indexing Carousel
Drives a rotary indexing table where the rear rod end mounts a cam, utilizing the 1402 N both-way force to push and pull loads with zero rotational backlash.
PCB Depaneling Saw Feed
Feeds a cutting blade through printed circuit boards, relying on the twin 20 mm rods to maintain blade alignment and prevent binding during the 90 mm traverse.
Multi-Stage Forming Press
Actuates a stamping die from both sides simultaneously, using the equal extend and retract forces to ensure perfectly balanced material forming.
Is the Airtac SED Double Rod Cylinder SED63X90 the Right Cylinder?
Selecting this 90 mm stroke model gives 1402 N both ways at 0.5 MPa. If your mechanism needs less force, step down to the 50 mm bore for 825 N; if you require more push, step up to the 80 mm bore for 2268 N. Choose this double-rod SED over a single-rod SE when the application demands dual-side guidance, rear-rod tooling, or superior anti-rotation resistance. Remember that a plain SED does not hold position on air loss—the piston drifts, and the adjustable cushion only decelerates near stroke end, acting as a brake rather than a lock. For fail-safe holding, consider a BSED or external rod lock. Ensure your ISO 15552 replacement matches the 63 mm bore, 90 mm stroke, PT3/8 port, and 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 SED63X90 FAQ
Because a rod exits both ends, the effective piston area is identical in both directions. The SED63X90 delivers 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa in both extend and retract.
The twin-rod design provides equal force and speed both ways, improves load guidance against rotation, and allows tooling or sensors to be mounted on the rear rod end. It is dimensionally interchangeable per ISO 15552 but omits FB, CA, CB, and CR mounting options.
