Airtac SED Double Rod Cylinder SED50X600S
The AirTAC SED Double Rod Cylinder SED50X600S 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 600mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X600S
The AirTAC SED50X600S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 600mm stroke. Because a 20mm rod exits both ends, the effective piston area is identical on extend and retract, yielding equal force in both directions—exactly 825N at 0.5 MPa and 1154N at 0.7 MPa. The extruded aluminum barrel contains no external tie rods, ensuring a clean profile that drops in dimensionally for any ISO 15552 footprint.
This S-variant includes a standard magnet for position sensing with CMSE reed or DMSE electronic sensors. Field-adjustable air cushions at both ends (30mm cushion length) allow you to tune deceleration for the long 600mm travel. Remember that the rear protruding rod requires clearance, but it provides excellent dual-side guidance and anti-rotation support for heavy carriage loads.

| 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 SED50X600S Is Used
Long-Stroke Transfer Carriage
Drives a 600mm packaging transfer carriage. The twin rods provide anti-rotation stability and deliver 825N of equal force both ways at 0.5 MPa to move heavy cardboard bales smoothly.
CNC Shuttle Loader
Shuttles raw aluminum billets into a machining center. The rear rod end mounts a DMSE electronic sensor flag for mid-stroke confirmation, while the 1154N force at 0.7 MPa pushes reliably.
Automated Welding Clamp
Actuates a double-clamp welding fixture. The equal both-way force ensures consistent 825N clamping and retraction pressure at 0.5 MPa, while the ISO 15552 profile eases fixture integration.
Is the Airtac SED Double Rod Cylinder SED50X600S the Right Cylinder?
Selecting this 50mm bore makes sense when your mechanism requires 825N of force both ways at 0.5 MPa. If you need less force, stepping down to the 40mm bore yields 528N both ways; if your load is heavier, stepping up to the 63mm bore provides 1402N. The double-rod design is preferred over a single-rod SE when your application demands high resistance to side loads, needs to prevent rotation, or requires mounting a rear cam and sensor flag.
For a 600mm stroke, external guide rails are strongly recommended to prevent rod binding and premature seal wear. Note that a plain SED50X600S will drift if air pressure drops—the adjustable cushion only decelerates near the stroke ends and does not lock position. For fail-safe holding, consider a BSED rod-lock cylinder or an external pilot-operated check valve. When replacing an ISO 15552 unit, match the 50mm bore, 600mm 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 SED50X600S FAQ
Because the double-rod design has a rod on both sides of the piston, force is equal in both directions. It provides 825N at 0.5 MPa, 1154N at 0.7 MPa, and a maximum of 168 kgf at 1.0 MPa.
The twin rods prevent piston rotation and support heavy loads over the 600mm stroke. The protruding rear rod also allows you to mount a rear cam or sensor flag. It uses a standard ISO 15552 mounting interface but omits FB, CA, CB, and CR mounts.
