Airtac SED Double Rod Cylinder SED50X65
The AirTAC SED Double Rod Cylinder SED50X65 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 65mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X65
The AirTAC SED50X65 is a double-acting, double-rod profile cylinder conforming to ISO 15552 / VDMA 24562. A 20mm rod exits both end covers, yielding identical annulus areas so thrust equals pull at 825N each way under 0.5MPa. The extruded aluminum barrel lacks external tie rods, providing a clean, dimensionally interchangeable direct for other ISO 15552 twin-rod units.
This 50mm bore unit travels 65mm and runs at 30-800mm/s. Field-adjustable air cushions at both ends decelerate the load near stroke extremes. Lacking the -S magnet option, this specific SKU cannot host CMSE or DMSE position sensors; external sensing must monitor the load.
Airtac SED Double Rod Cylinder SED50X65 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED50X65 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 65 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 |
| Max stroke | Up to 1200 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 SED50X65 Is Used
Web Guide Mechanism
Equal 825N force both ways stabilizes a 50mm web guide roller, using the rear rod end for a tensioning cam without drift asymmetry.
Shuttle Transfer
Twin rods prevent binding in a short 65mm parts shuttle, delivering 1154N at 0.7MPa to push and pull components between machining stations.
Spot Welding Head
The through-rod design carries a rear limit flag for timing the 168kgf max weld head approach, ensuring precise electrode alignment.
Is the Airtac SED Double Rod Cylinder SED50X65 the Right Cylinder?
Select this 1154N (at 0.7MPa) actuator when a load demands equal push-pull dynamics or anti-rotation guidance. If your mechanism requires less force, the adjacent 40mm bore provides 528N at 0.5MPa. Stepping up to the 63mm bore yields 1402N at 0.5MPa for heavier resistance. Unlike a single-rod SE cylinder, this through-rod design allows mounting a cam or secondary tool on the rear extension.
Remember that a standard SED50X65 drifts upon air loss; the adjustable cushion only decelerates near end-of-stroke and provides no fail-safe holding. For position locking on air failure, specify a BSED rod-lock cylinder or an external pilot-operated check valve. The PT1/4 port and M16x1.5 rod thread match standard 50mm ISO 15552 hardware.
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 SED50X65 FAQ
Because the double-rod design creates equal piston annulus areas, the force is identical in both directions: 825N at 0.5MPa, 1154N at 0.7MPa, and a maximum of 168kgf at 1.0MPa.
Yes. The SED50X65 is a true ISO 15552 profile cylinder with a standard PT1/4 port and 20mm rod. It offers direct dimensional interchangeability for any ISO 15552 twin-rod cylinder, though you must ensure your mounting accessory is from the Basic, FA, LB, TC, FTC, TCM1, or TCM2 set.
