Airtac SED Double Rod Cylinder SED50X210
The AirTAC SED Double Rod Cylinder SED50X210 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 210mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X210
The AirTAC SED50X210 is a double-acting, double-rod profile cylinder built to ISO 15552 dimensions. Because a Ø20 mm rod extends from both end covers, the annulus area is identical on each side. This means you get exactly 825 N of output force at 0.5 MPa in both extend and retract directions.
This unit features an extruded aluminum barrel with no external tie rods, adjustable air cushioning at both ends, and a PT1/4 port. Note that this specific SKU lacks a magnet; position sensing via CMSE or DMSE switches is not supported without a different option code. The rear rod protrusion allows mounting a secondary cam or limit flag.

| 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 SED50X210 Is Used
PCB Edge Deburring
Drives a dual-sided deburring blade with 825 N of equal force, ensuring consistent pressure on both extend and retract strokes for flawless board edges.
Pallet Transfer Gate
Uses the twin rods to push and pull a diverter gate without twisting, maintaining precise alignment during high-speed conveyor sorting tasks.
Film Roll Splicing
Clamps a rotating splice head from both ends via the through-rod, delivering balanced 1154 N holding at 0.7 MPa to secure packaging material layers.
Is the Airtac SED Double Rod Cylinder SED50X210 the Right Cylinder?
Choose this 50 mm bore when you need 825 N of equal both-way force at 0.5 MPa. If your load is lighter, stepping down to the 40 mm bore yields 528 N both ways. For heavier drives, the 63 mm bore provides 1402 N. The twin-rod design inherently resists torsional rotation better than a single-rod SE cylinder, making it ideal for guided lifts. Since this is a plain pneumatic actuator, it will drift on air loss—the adjustable cushion only decelerates near stroke end, so use a BSED or external lock for fail-safe holding.
At 210 mm of stroke, the extended rod length requires careful rear-clearance planning. Furthermore, the long twin rods are susceptible to bending under lateral stress; always pair this cylinder with external linear guides to prevent side-load damage. To replace an existing ISO 15552 unit, match the 50 mm bore, 210 mm 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 SED50X210 FAQ
The drive force is equal in both directions due to the double-rod design. It outputs 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and reaches a maximum of 168 kgf at 1.0 MPa.
No. A standard SED cylinder will drift downward if air pressure is lost, as the adjustable air cushion only decelerates the piston near stroke end and does not lock it. For fail-safe position holding, you need a BSED double-rod rod-lock cylinder or an external pilot-operated check valve.
