Airtac SED Double Rod Cylinder SED63X145
The AirTAC SED Double Rod Cylinder SED63X145 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 145mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X145
The AirTAC SED63X145 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 145mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding equal force in both directions—about 1402 N each way at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, ensuring clean integration. This unit lacks the standard magnet option, meaning it cannot directly host CMSE or DMSE position sensors without modification.
Equipped with a PT3/8 port, a Ø20 mm rod, and an M16x1.5 rod-end thread, it handles dynamic loads effectively. The field-adjustable air cushion at both ends decelerates the piston near stroke ends, though it does not function as a locking brake. The rear rod extension can drive a secondary mechanism or mount a cam, providing superior anti-rotation guidance compared to single-rod SE cylinders.

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 145 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 SED63X145 Is Used
PCB Panel Transfer
Drives a dual-sided pusher arm in a PCB handling line, using the 1402 N both-way force to shuttle panels without rotational skew.
Web Guide Tensioner
Adjusts a web material guide roller via the rear rod end, relying on twin-rod anti-rotation to keep the web tracking true.
Parts Ejector Station
Ejects machined aluminum parts from a fixture using equal extend and retract speeds, preventing cycle timing asymmetry.
Is the Airtac SED Double Rod Cylinder SED63X145 the Right Cylinder?
Choose this 63mm bore when you need 1402 N of bidirectional force at 0.5 MPa. If your load is lighter, the 50mm bore provides 825 N both ways; if heavier, stepping up to the 80mm bore yields 2268 N both ways. The double-rod design is essential over a single-rod SE when your application demands high resistance to torsional side loads or requires driving a mechanism from the rear rod. Remember that a plain SED does not hold position on air loss—the piston will drift. For fail-safe holding, consider an AirTAC BSED double-rod lock or an external pilot-operated check valve. When replacing an existing ISO 15552 cylinder, match the 145mm stroke, PT3/8 port, and mounting interface (Basic, FA, LB, TC, FTC, TCM1, or TCM2—note that FB, CA, CB, and CR are omitted from this series).
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 SED63X145 FAQ
The SED63X145 provides equal force in both directions because of the double-rod design. It delivers 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa.
Yes, the SED63X145 is dimensionally interchangeable per ISO 15552 / VDMA 24562. Ensure you match the 63mm bore, 145mm stroke, PT3/8 port, and select from the available mounting sets (Basic, FA, LB, TC, FTC, TCM1, TCM2).
