Airtac SED Double Rod Cylinder SED50X300
The AirTAC Airtac SED Double Rod Cylinder SED50X300 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 300mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X300
The AirTAC SED50X300 is a double-acting, double-rod profile cylinder built to the ISO 15552 interface. Because a Ø20 mm rod extends from both end covers, the annulus area is identical on both sides, yielding equal thrust in and out—exactly 825 N each way at 0.5 MPa. The extruded aluminum barrel omits external tie rods for a clean profile.
This 300 mm stroke unit uses PT1/4 ports and M16x1.5 rod threads. Field-adjustable air cushions at both ends decelerate the load near stroke extremes. Note this SKU lacks a magnet, so it cannot host CMSE or DMSE sensors without modification.
Airtac SED Double Rod Cylinder SED50X300 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED50X300 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 300 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 SED50X300 Is Used
Packaging Line Diverter
Drives a dual-sided pusher arm at 825 N to split cartons on a packaging conveyor without rotational skew.
PCB Edge Trimmer
Carries a cutting blade on one rod and a limit flag on the rear rod, maintaining precise alignment during board trimming.
Textile Web Guide
Uses the twin-rod anti-rotation property to steer fabric webs evenly, preventing snags during high-speed processing.
Is the Airtac SED Double Rod Cylinder SED50X300 the Right Cylinder?
Step down to a 40 mm bore for 528 N, or up to a 63 mm bore for 1402 N at 0.5 MPa. Choose this 50 mm double-rod over a single-rod SE when you need to mount a cam or sensor flag on the rear rod, or when twin-side guidance is required to prevent load rotation. It is dimensionally interchangeable with any ISO 15552 double-rod cylinder.
At 300 mm stroke, the extended rod length increases susceptibility to side loads; ensure external guide rails carry the load. Remember, a plain SED does not hold position on air loss—piston drift occurs. For fail-safe holding, use a BSED double-rod lock or external 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 SED50X300 FAQ
Because the double-rod design has equal piston areas on both sides, it generates 825 N at 0.5 MPa and 1154 N at 0.7 MPa in both directions, with a maximum of 168 kgf at 1.0 MPa.
The twin rods provide equal force and speed in both directions and resist load rotation. The rear rod can drive a secondary mechanism or sensor flag, and it drops into any standard ISO 15552 mounting footprint.
