Airtac SED Double Rod Cylinder SED50X225
The AirTAC Airtac SED Double Rod Cylinder SED50X225 is a genuine double-acting ISO 15552 double-rod cylinder: a Ø20mm piston rod exits BOTH ends of the Ø50mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 225mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X225
The AirTAC SED50X225 is a double-acting, double-rod ISO 15552 profile cylinder engineered for symmetrical load handling. Because a 20mm rod exits both end covers, the annular piston area is identical on extend and retract. This yields equal force both ways, generating 825 N at 0.5 MPa and 1154 N at 0.7 MPa in either direction.
This unit features an extruded aluminum barrel without external tie rods, running at 30-800 mm/s. Adjustable air cushions at both ends decelerate the 225mm stroke. This specific SKU lacks the -S magnet option, meaning it cannot host CMSE or DMSE position sensors without modification.

| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 225 mm |
| Configuration | Double rod, double acting |
| Port size | PT1/4 |
| 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, 30 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 (Ø50mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 825 N |
| 0.7 MPa | 1155 N |
| Max (@1.0 MPa) | 168 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 SED50X225 Is Used
PCB Edge Deburring
Drives a clamping fixture with 825 N of equal force in both directions, ensuring delicate circuit boards are held flat without rotational skew during the deburring process.
Textile Web Steering
Uses the twin-rod architecture to guide a fabric roller from both ends simultaneously, preventing snags while maintaining consistent tension across the 225mm stroke.
Dual-Side Label Press
Actuates opposing label applicators where the rear rod end cams a secondary mechanism, leveraging the 1154 N output at 0.7 MPa for crisp, synchronized placement.
Is the Airtac SED Double Rod Cylinder SED50X225 the Right Cylinder?
Selecting this 50mm bore provides 825 N of bidirectional force at 0.5 MPa. If your application requires less thrust, step down to the 32mm bore (345 N both ways); if you need more power, step up to the 63mm bore (1402 N both ways). The twin-rod design is chosen over a single-rod SE cylinder when you need superior anti-rotation resistance or wish to drive a secondary mechanism from the rear rod end.
As a true ISO 15552 cylinder, it drops in dimensionally for any standard double-rod footprint using PT1/4 ports and an M16x1.5 rod thread. Note that the rear protruding rod requires clearance. Because the 225mm stroke exceeds 300mm? No, but at 225mm you should still ensure external load guides to prevent side-load binding. A plain SED does not hold position on air loss; for fail-safe holding, use a BSED double-rod rod lock.
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 SED50X225 FAQ
The SED50X225 provides equal force in both extend and retract directions due to its double-rod design. It outputs 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and reaches a maximum of 168 kgf at 1.0 MPa.
Yes. The SED50X225 is a true ISO 15552 / VDMA 24562 profile cylinder. It is dimensionally interchangeable with any standard ISO 15552 double-rod cylinder matching its 50mm bore, 225mm stroke, PT1/4 port, and M16x1.5 rod thread. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
