Airtac SED Double Rod Cylinder SED63X90S
The AirTAC Airtac SED Double Rod Cylinder SED63X90S 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 SED63X90S
The AirTAC SED63X90S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensions. A 20mm rod exits both end covers, yielding equal effective piston areas and identical thrust in both directions. You get 1402 N of force each way at 0.5 MPa, and 1962 N at 0.7 MPa.
This unit includes the -S magnet for position sensing using CMSE reed or DMSE electronic switches. The protruding rear rod can mount a secondary cam or limit flag, while the twin-rod geometry resists torsional rotation better than a single-rod SE cylinder.

|---|---|
| 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 |

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 SED63X90S Is Used
Web Guiding Mechanism
Drives a paper or film web guide with 1402 N at 0.5 MPa. The twin rods prevent chassis twist during rapid directional reversals.
Shuttle Transfer Arm
Moves parts between two conveyors. The rear rod end mounts a cam to trigger a downstream pick-and-place at the exact stroke midpoint.
Equal-Power Pressing Stand
Presses bearings into housings. Because the annular area is identical both ways, the press applies 1962 N of force at 0.7 MPa on both the advance and return strokes.
Is the Airtac SED Double Rod Cylinder SED63X90S the Right Cylinder?
Choose this 63mm bore when your process requires matched extend and retract forces of 1402 N at 0.5 MPa. If your load is lighter, step down to the 50mm bore providing 825 N both ways; if heavier, step up to the 80mm bore yielding 2268 N. At 90mm stroke, side loading is minimal, but external guides remain best practice for rigid loads.
Unlike a single-rod SE cylinder, the SED allows you to drive a secondary mechanism from the rear rod end. Remember that a standard SED does not hold position on air loss—the piston will drift. For fail-safe holding, specify a BSED double-rod lock cylinder or add an external pilot-operated check valve. Drop-in ISO 15552 replacement requires matching the 90mm 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 SED63X90S FAQ
Because the double-rod design creates equal effective piston areas on both sides, force is identical in both directions. It delivers 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 resistance to torsional rotation and allows the rear rod end to drive a secondary mechanism or sensor flag. It also ensures perfectly matched extend and retract speeds for shuttle applications.
