Airtac SED Double Rod Cylinder SED63X225
The AirTAC Airtac SED Double Rod Cylinder SED63X225 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 SED63X225
The AirTAC SED63X225 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 225mm stroke. Because a rod exits both ends, the annular piston area is symmetrical, yielding identical extend and retract forces of 1402 N at 0.5 MPa. This eliminates directional force mismatch for push-pull tooling.
The twin-rod architecture provides superior anti-rotation guidance compared to a single-rod SE cylinder. The extending rear rod can mount a cam or secondary mechanism. It uses a PT3/8 port, a Ø20 mm rod with an M16x1.5 thread, and field-adjustable air cushions at both ends. This specific SKU lacks the -S magnet, so it has no built-in position sensing.

| 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 SED63X225 Is Used
Precision Grinding Slides
Drives a grinding head carriage with 1402 N both ways at 0.5 MPa, utilizing twin rods to prevent rotational deflection during aggressive material removal.
Dual-Side Transfer Gates
Actuates a synchronized diverter gate where the rear rod simultaneously operates a mechanical flag, ensuring perfectly timed product sorting.
Injection Mold Ejection
Pushes and pulls a mold ejection plate with equal 1962 N force at 0.7 MPa, guaranteeing consistent part release without directional force spikes.
Is the Airtac SED Double Rod Cylinder SED63X225 the Right Cylinder?
Select the 63mm bore when you need exactly 1402 N of both-way force at 0.5 MPa. If your load is lighter, the 50mm bore provides 825 N both ways; if you need more thrust, step up to the 80mm bore for 2268 N. At 225mm stroke, the 20mm rod is robust, but always support long loads with external guides to prevent bending.
A double rod outperforms a single-rod SE when driving heavy sliding carriages or parts requiring strict rotational stability. Remember that a standard SED does not hold position on air loss—the piston drifts, and the cushion only decelerates near stroke end. For fail-safe holding, use a BSED rod lock. As a true ISO 15552 cylinder, it drops in dimensionally for any standard profile double-rod footprint using Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts (omitting FB, CA, CB, CR).
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 SED63X225 FAQ
Because the double-rod design creates equal annular areas on both sides, the 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.
Yes, it is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 double-rod units. Just match the 63mm bore, 225mm stroke, PT3/8 port, and mounting style (it supports Basic, FA, LB, TC, FTC, TCM1, TCM2).
