Airtac SED Double Rod Cylinder SED63X225S
The AirTAC SED Double Rod Cylinder SED63X225S 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 225mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X225S
The AirTAC SED63X225S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a rod extends from both end covers, the annulus area is identical on both sides, yielding exactly 1402 N of force at 0.5 MPa in both extend and retract directions. The extruded aluminum barrel eliminates external tie rods, and the included -S magnet enables position tracking with CMSE reed or DMSE electronic sensors.
This 63mm bore unit features a PT3/8 port, a 20mm rod with an M16x1.5 thread, and field-adjustable air cushioning at both ends. The rear rod protrusion allows you to mount a secondary cam or sensor flag while providing superior anti-rotation guidance for the payload.

| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 225 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 SED63X225S Is Used
PCB Edge Trimming
Drives a dual-sided trimming blade carriage with 1402 N at 0.5 MPa. The twin rods keep the cutting head perfectly parallel, preventing blade chatter.
Pallet Transfer
Shifts work pallets between conveyor lanes. The rear rod actuates a mechanical sync flag while the front rod pushes the 1962 N load at 0.7 MPa.
Mold Ejection
Ejects silicone molds from a static die. Equal both-way force ensures positive ejection and smooth retraction without snapping the delicate parts.
Is the Airtac SED Double Rod Cylinder SED63X225S the Right Cylinder?
Choose this 63mm bore if your application requires roughly 1962 N at 0.7 MPa. If you need less force, the neighboring 50mm bore provides 825 N at 0.5 MPa; stepping up to the 80mm bore yields 2268 N at 0.5 MPa. The twin-rod design is preferred over a single-rod SE cylinder when you need to drive two mechanisms in tandem, mount rear tooling, or resist torsional side loads.
With a 225mm stroke, external guide rails are recommended to prevent rod binding under offset loads. Note that a plain SED does not hold position on air loss—the piston drifts, and the adjustable cushion only decelerates near stroke end. For fail-safe holding, consider a BSED double-rod rod lock. To replace an existing ISO 15552 cylinder, match the 225mm stroke, PT3/8 port, desired mounting (Basic, FA, LB, TC, FTC, TCM1, or TCM2), and the -S magnet option.
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 SED63X225S FAQ
Because the double-rod design has equal piston areas on both sides, 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 twin rods provide equal force and speed in both directions, resist rotational torque better than a single rod, and allow you to mount rear-side tooling or sensors. It is dimensionally interchangeable with other ISO 15552 double-rod cylinders.
