Airtac SED Double Rod Cylinder SED63X140S
The AirTAC SED Double Rod Cylinder SED63X140S 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 140mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X140S
The AirTAC SED63X140S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a rod extends from both end covers, the annular piston area is identical on both sides, yielding exactly 1402 N of force in both extend and retract directions at 0.5 MPa. The extruded aluminum barrel eliminates external tie rods for a clean profile.
Equipped with a standard magnet (-S), this 63mm bore unit triggers CMSE reed or DMSE electronic sensors flush-mounted in the barrel groove. The rear rod extension is ideal for mounting a limit flag, driving a secondary mechanism, or providing anti-rotation guidance. It features field-adjustable air cushioning at both ends and a PT3/8 port.

| 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 |

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 SED63X140S Is Used
PCB Lifting Jig
Drives a vertical lift arm in a PCB handling line. The 1402N both-way force securely raises the panel, while the rear rod operates a cam for a pneumatic clamp.
Pallet Pusher
Pushes workpieces transversely across a conveyor. The twin rods prevent the pusher plate from twisting under the 1402N thrust, ensuring square transfers.
Indexing Gate
Actuates a diverter gate on a packaging sorter. The equal extend and retract speeds keep the indexing rhythm consistent without needing flow controls.
Is the Airtac SED Double Rod Cylinder SED63X140S the Right Cylinder?
Choose this 63mm bore if your application requires 1402 N at 0.5 MPa (or 1962 N at 0.7 MPa) with equal thrust both ways. If you need less force, step down to the 50mm bore (825 N at 0.5 MPa); if you need more, step up to the 80mm bore (2268 N at 0.5 MPa). The twin-rod design provides superior anti-rotation resistance compared to a single-rod SE cylinder, making it ideal for guided loads.
To replace an ISO 15552 cylinder, match the 140mm stroke, 63mm bore, PT3/8 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that a plain SED does not hold position on air loss; the piston will drift. For fail-safe holding, use an external rod lock or a BSED double-rod rod-lock cylinder. Since the stroke is under 300mm, side-load stress is minimal, but external guides are still recommended for heavy lateral loads.
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 SED63X140S FAQ
Because the double-rod design has equal piston area on both sides, output force is identical 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 SED twin-rod design provides superior anti-rotation stability and allows the rear rod to drive a secondary mechanism or sensor flag. It also ensures equal force and speed in both directions, which is critical for synchronized indexing tasks.
