Airtac SED Double Rod Cylinder SED50X260
The AirTAC SED Double Rod Cylinder SED50X260 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 260mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X260
The AirTAC SED50X260 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 260mm stroke. Because a rod exits both ends, the annulus area is identical on both sides, delivering an equal 825 N of drive force in extend and retract at 0.5 MPa. The extruded aluminum barrel avoids external tie rods, ensuring clean integration.
This unit uses a PT1/4 port and a 20mm rod with an M16x1.5 thread. Adjustable air cushions at both ends manage end-of-stroke deceleration. This specific SKU lacks a piston magnet, meaning it is not equipped for CMSE or DMSE position sensing out of the box.

| 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 (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 SED50X260 Is Used
Web Guiding Mechanism
Uses the 825 N equal both-way force to push and pull a paper web guide evenly, relying on the twin rods to prevent binding during 260mm strokes.
Dual-Side Conveyor Diverter
Mounts through a machine frame to actuate a diverting gate from the rear rod end while the front rod drives a second lane, maximizing layout density.
PCB Lift and Lower Station
Raises delicate electronics with balanced 1154 N force at 0.7 MPa, using the double-rod symmetry to avoid cantilever sag on the 260mm travel.
Is the Airtac SED Double Rod Cylinder SED50X260 the Right Cylinder?
Choose this 50mm bore when you need 825 N of equal both-way force at 0.5 MPa. If your application requires less force, step down to the 40mm bore providing 528 N; if you need more power, step up to the 63mm bore yielding 1402 N. The twin-rod design provides superior anti-rotation resistance and allows driving a secondary mechanism from the rear rod end.
Because this 260mm stroke exceeds 300mm is not the case here, but at 260mm you should still evaluate external guides for heavy lateral loads. A plain SED does not hold position upon air loss; the piston drifts. For fail-safe holding, select a BSED double-rod rod lock or use an external pilot-operated check valve. To replace an ISO 15552 unit, match the 50mm bore, 260mm stroke, PT1/4 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
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 SED50X260 FAQ
The SED50X260 provides equal force in both directions due to the double-rod design. It outputs 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and a maximum of 168 kgf at 1.0 MPa.
No. The adjustable air cushions only decelerate the piston near the stroke ends; they do not lock position. Upon air loss, the piston will drift. For fail-safe holding, use an AirTAC BSED double-rod rod lock cylinder or an external locking device.
