Airtac SED Double Rod Cylinder SED40X130
The AirTAC Airtac SED Double Rod Cylinder SED40X130 is a genuine double-acting ISO 15552 double-rod cylinder: a Ø16mm piston rod exits BOTH ends of the Ø40mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 130mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED40X130
The AirTAC SED40X130 is a double-acting, double-rod profile cylinder built to ISO 15552 standards. Because a 16mm rod exits both end covers, the effective piston area is identical on extension and retraction, yielding an equal 528N of force each way at 0.5 MPa. This symmetry is vital for mechanisms requiring perfectly balanced push-pull dynamics.
The extruded aluminum barrel contains no external tie rods, ensuring a clean profile that drops into standard ISO 15552 mounting interfaces. Field-adjustable air cushions at both ends decelerate the load near the 130mm stroke limits. Note this specific SKU lacks a standard magnet, so it cannot directly host CMSE or DMSE position sensors without modification.

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 130 mm |
| Configuration | Double rod, double acting |
| Port size | PT1/4 |
| Rod thread | M12×1.25 |
| 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 (Ø40mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 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 SED40X130 Is Used
Web Guiding Mechanism
Provides 528N of equal thrust in both directions to steer paper or film webs precisely without rotational lag.
Dual-Side Parts Ejector
Uses the twin 16mm rods to push identical parts from two fixtures simultaneously during machining cycles.
Transfer Gate Diverter
Leverages the rear rod end to mount a cam, synchronizing a diverting flap with the main stroke motion.
Is the Airtac SED Double Rod Cylinder SED40X130 the Right Cylinder?
Selecting this 40mm bore provides 528N both ways at 0.5 MPa. If your payload is lighter, step down to the 32mm bore for 345N; if your mechanism demands more thrust, step up to the 50mm bore for 1154N. Choose this double-rod SED over a single-rod SE when your application requires anti-rotation guidance, a rear-rod cam for secondary actuation, or perfectly symmetrical velocity.
To replace an ISO 15552 unit, match the 40mm bore, 130mm stroke, PT1/4 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Remember that a plain SED does not hold position on air loss—the piston will drift. For fail-safe holding, consider a BSED double-rod lock cylinder or an external rod lock.
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 SED40X130 FAQ
Because the double-rod design subtracts the rod area from both sides, force is equal in both directions: 528N at 0.5 MPa, 739N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa.
The twin-rod design prevents piston rotation, offers better load guidance, and allows tooling or cams on the rear rod. It is dimensionally interchangeable with ISO 15552 profile cylinders.
