Airtac SED Double Rod Cylinder SED80X15
The AirTAC Airtac SED Double Rod Cylinder SED80X15 is a genuine double-acting ISO 15552 double-rod cylinder: a Ø25mm piston rod exits BOTH ends of the Ø80mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 15mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X15
The AirTAC SED80X15 is a double-acting, double-rod profile cylinder fully dimensionally interchangeable per the ISO 15552 standard. Because a Ø25 mm rod occupies both sides of the 80 mm piston, the annulus area is identical in both directions, yielding an equal force of 2268 N each way at 0.5 MPa. The extruded aluminum barrel has no external tie rods, keeping the footprint clean while providing integrated sensor grooves.
This specific SKU lacks the -S magnet option, meaning it cannot carry CMSE reed or DMSE electronic sensors. It retains field-adjustable air cushions at both ends (36 mm cushion length) to decelerate the load near stroke extremes. The rear rod extension can be used to mount a cam or drive a secondary mechanism, providing superior anti-rotation guidance compared to a single-rod SE cylinder.

| Port size | PT3/8 |
| Rod thread | M20×1.5 |
| 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, 36 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 (Ø80mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 2268 N |
| 0.7 MPa | 3175 N |
| Max (@1.0 MPa) | 463 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 SED80X15 Is Used
Web Guiding Brakes
Applies 2268 N of equal tension both ways to hold and adjust web materials in printing or converting machinery without rotational drift.
Dual-Side Transfer Jaws
Drives synchronized pick-and-place jaws using the rear rod for a cam follower, ensuring perfectly balanced 3175 N motion at 0.7 MPa.
Press Pin Ejection
Ejects machined pins from a press die using equal push-pull force, leveraging the short 15 mm stroke for rapid, compact ejection cycles.
Is the Airtac SED Double Rod Cylinder SED80X15 the Right Cylinder?
Choose this 80 mm bore if your mechanism requires 2268 N of both-way force at 0.5 MPa (or 3175 N at 0.7 MPa). If you need less force, step down to the 63 mm bore which provides 1402 N both ways at 0.5 MPa. If your application demands more power, the 100 mm bore offers 3681 N both ways at 0.5 MPa. The twin-rod design is essential when you need equal push-pull dynamics, anti-rotation stability, or rear-rod tooling. This unit uses a PT3/8 port and M20x1.5 rod thread.
Because the stroke is only 15 mm, side-load stress is minimal, but always ensure the load is guided externally. A plain SED does not hold position on air loss; the piston will drift. The adjustable air cushion only decelerates near the stroke end and is not a brake. For fail-safe holding, consider a BSED double-rod rod lock cylinder or an external pilot-operated check valve.
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 SED80X15 FAQ
The SED80X15 provides equal force in both directions because the rod exits both ends. It delivers 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and a maximum of 463 kgf at 1.0 MPa.
Yes, it is a true ISO 15552 profile cylinder with no external tie rods. You can drop it in for other ISO 15552 double-rod units. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (FB, CA, CB, and CR are omitted).
