Airtac SED Double Rod Cylinder SED50X270S
The AirTAC SED Double Rod Cylinder SED50X270S 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 270mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X270S
The AirTAC SED50X270S is a double-acting, double-rod profile cylinder built to the ISO 15552 interface. A 20mm rod exits both end covers, yielding identical annulus areas so the cylinder outputs 825 N in both directions at 0.5 MPa. The extruded aluminum barrel omits external tie rods, offering a clean ISO 15552 direct profile.
Fitted with a magnet (-S), this unit directly mounts CMSE reed or DMSE electronic sensors in the integrated barrel groove. Field-adjustable air cushions at both ends provide 30mm of deceleration. The rear rod extension can drive a secondary mechanism or carry a limit flag, while adding overall length that requires rear clearance.
Airtac SED Double Rod Cylinder SED50X270S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED50X270S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 270 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 SED50X270S Is Used
Web Edge Guiding
Equal 825 N force both ways stabilizes film or paper webs against torsion during 270mm positioning shifts.
Dual-Side Grippers
The twin 20mm rods prevent jaw rotation during part transfer, driving synchronized clamps at 1154 N at 0.7 MPa.
PCB Shuttle Conveyor
Rear rod end mounts a DMSE electronic sensor flag to track stroke limits while the front rod shuttles boards.
Is the Airtac SED Double Rod Cylinder SED50X270S the Right Cylinder?
Select this 50mm bore when an application demands equal 825 N push and pull forces alongside anti-rotation stability. If your load requires less force, the 40mm bore provides 528 N both ways at 0.5 MPa; if you need more thrust, step up to the 63mm bore for 1402 N. Unlike a single-rod SE cylinder, this twin-rod design guides the load against torsion and enables rear-end sensing. For a 270mm stroke, add external guide rails to manage side loads and prevent rod binding. A plain SED does not hold position on air loss; for fail-safe holding, use a BSED double-rod lock or external pilot-operated check valve. Confirm replacement dimensions by bore, stroke, PT1/4 port, and mounting type (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 SED50X270S FAQ
Because a rod occupies both piston sides, 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 rods provide superior anti-rotation guidance for the load and allow rear-end sensor mounting. It is dimensionally interchangeable per ISO 15552, though the through-rod design requires rear clearance.
