Airtac SED Double Rod Cylinder SED50X5
The AirTAC SED Double Rod Cylinder SED50X5 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 5mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X5
The AirTAC SED50X5 is a double-acting, double-rod profile cylinder delivering 825 N of force each way at 0.5 MPa. Because a rod exits both ends, the annulus area is identical on extend and retract, providing perfectly symmetrical thrust and speed for demanding short-stroke tasks.
Built to the ISO 15552 interface with an extruded aluminum barrel, it features a 20 mm rod, PT1/4 port, and adjustable air cushions at both ends. This SKU lacks a magnet, so it does not support CMSE or DMSE position sensing without modification.
Airtac SED Double Rod Cylinder SED50X5 Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 5 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 SED50X5 Is Used
Gripper Jaw Actuation
Drives symmetrical gripper jaws using the equal 825 N both-way force, ensuring perfectly balanced clamping pressure on delicate machined parts.
Short-Stroke Diverter
Uses the twin rods to push a diverter gate from either side, leveraging the anti-rotation properties to keep the flap stable during high-speed sorting.
Spot Welding Pinch
Applies symmetrical 1154 N force at 0.7 MPa for small resistance welding tips, using the rear rod end to mount a mechanical cam limit flag.
Is the Airtac SED Double Rod Cylinder SED50X5 the Right Cylinder?
Choose this 50 mm bore to generate 825 N both ways at 0.5 MPa. If your payload is lighter, step down to the 40 mm bore for 528 N; for heavier loads, step up to the 63 mm bore providing 1402 N. The 5 mm stroke is extremely short, minimizing overall length, but you must still account for rear-rod protrusion clearance.
The twin-rod design excels at anti-rotation and driving dual mechanisms simultaneously. Remember that a plain SED does not hold position on air loss—the piston drifts, and the cushion only decelerates near the end of stroke. For fail-safe holding, use a BSED or external lock. Match ISO 15552 dimensions by verifying the 50 mm bore, 5 mm stroke, PT1/4 port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, 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 SED50X5 FAQ
The double-rod design provides equal force 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 rods provide superior anti-rotation resistance and allow you to mount tooling or a cam on the rear rod end. It also ensures the speed and force are perfectly identical on extend and retract.
