Airtac SED Double Rod Cylinder SED40X80S
The AirTAC Airtac SED Double Rod Cylinder SED40X80S 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 80mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED40X80S
The AirTAC SED40X80S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 80mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding an equal force of 528 N each way at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, ensuring a clean profile that drops in for any ISO 15552 dimensional replacement.
Fitted standard with a magnet for position detection, this unit triggers CMSE reed or DMSE electronic sensors housed in the integrated barrel grooves. The twin-rod architecture provides superior anti-rotation guidance for loads and allows the rear rod end to drive a secondary mechanism or cam. Field-adjustable air cushioning at both ends manages end-of-stroke deceleration across the 30-800 mm/s speed range.

| 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 SED40X80S Is Used
PCB Depaneling Saw
Drives a synchronized cutting blade from the rear rod while the front rod pushes boards, utilizing the 528 N equal both-way force to prevent blade binding.
Pneumatic Indexing Gate
Actuates a heavy automated assembly gate where the twin 16mm rods provide anti-rotation guidance, ensuring the cam returns perfectly straight without twisting.
Textile Web Guide
Aligns fabric edges by shifting a roller simultaneously from both ends, relying on the 739 N bidirectional output to maintain consistent tension across the web.
Is the Airtac SED Double Rod Cylinder SED40X80S the Right Cylinder?
Select this 40mm bore when your application requires 528 N of bidirectional force at 0.5 MPa (739 N at 0.7 MPa, 108 kgf max at 1.0 MPa). If you need less force, step down to the 32mm bore delivering 345 N both ways; if your payload is heavier, step up to the 50mm bore providing 825 N both ways. Choose this double-rod SED over a single-rod SE when the mechanism demands dual-side guidance to prevent twisting, or requires rear-rod tooling and sensing. For a true ISO 15552 replacement match, verify the 80mm stroke, PT1/4 port, M12x1.25 rod thread, and mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that a plain SED does not hold position on air loss; for fail-safe holding, consider an external rod lock or the BSED series.
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 SED40X80S FAQ
The SED40X80S provides equal force in both directions due to its double-rod design. It outputs 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa.
The double-rod design ensures identical extend and retract forces, prevents load rotation via dual-side guidance, and allows the rear rod to mount secondary cams or sensors. It is dimensionally interchangeable with other ISO 15552 cylinders but omits the FB, CA, CB, and CR mounting styles.
