Airtac SED Double Rod Cylinder SED50X45S
The AirTAC SED Double Rod Cylinder SED50X45S 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 45mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X45S
The AirTAC SED50X45S is a double-acting, double-rod profile cylinder built to the ISO 15552 dimensional interface. A 20mm rod extends from both end covers, yielding an identical annulus area on each side. This means you get 825 N of output force at 0.5 MPa in both extend and retract directions.
Equipped with a -S magnet, this 50mm bore unit supports CMSE reed and DMSE electronic sensors for end-of-stroke signaling. The extruded aluminum barrel omits external tie rods, and adjustable air cushions at both ends manage kinetic energy near the 45mm stroke limits.
Airtac SED Double Rod Cylinder SED50X45S Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 45 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 SED50X45S Is Used
PCB Edge Guiding
Uses the 825 N equal both-way force to center electronic panels without rotational deflection during transit.
Dual-Side Labeling
Drives opposing applicator heads simultaneously via the rear rod extension while maintaining precise parallelism.
Gripper Actuation
Provides stable 45mm stroke clamping where the twin rods resist twisting moments from off-center part loading.
Is the Airtac SED Double Rod Cylinder SED50X45S the Right Cylinder?
Choose this 50mm bore if your application requires 825 N of equal bidirectional force at 0.5 MPa. Stepping down to the 32mm bore drops the both-way output to 345 N, while moving up to the 63mm bore raises it to 1402 N. The twin-rod architecture provides superior anti-rotation stability compared to a single-rod SE cylinder, and the protruding rear rod can drive a secondary mechanism or sensor flag.
For ISO 15552 direct replacements, match the 50mm bore, 45mm stroke, PT1/4 port, and -S magnet. Note that the SED mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, explicitly omitting FB, CA, CB, and CR brackets. A plain SED does not hold position upon air loss; the piston will drift. For fail-safe holding, use a BSED double-rod rod lock or an external pilot-operated check valve.
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 SED50X45S FAQ
Because the double-rod design has equal piston areas on both sides, the force is identical in both directions: 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and a maximum of 168 kgf at 1.0 MPa.
The twin 20mm rods prevent load rotation better than a single-rod SE cylinder, allow the rear rod end to mount a cam or secondary mechanism, and ensure push and pull forces remain exactly equal throughout the 45mm stroke.
