Airtac SED Double Rod Cylinder SED80X75S
The AirTAC Airtac SED Double Rod Cylinder SED80X75S 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 75mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X75S
The AirTAC SED80X75S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 25 mm rod exiting both end covers. Because the rod occupies both sides of the piston, the annulus area is identical in each direction. This yields equal force and speed on extend and retract, delivering 2268 N each way at 0.5 MPa.
The integrated -S magnet enables position sensing using CMSE reed or DMSE electronic switches. A field-adjustable air cushion at both ends decelerates the load near stroke end, while the extruded aluminum barrel omits external tie rods for a clean ISO 15552 footprint.

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 75 mm |
| Configuration | Double rod, double acting |
| 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 |
| Max stroke | Up to 1500 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 SED80X75S Is Used
Servo Press Peening
Drives a dual-sided peening head with 3175 N at 0.7 MPa, using the rear rod to mirror a secondary anvil strike without rotational deflection.
Pallet Transfer Divert
Shifts heavy pallets laterally using equal both-way force, ensuring consistent cycling speed and stable load guiding across the 75 mm stroke.
Gripping Cam Actuation
Powers an external cam mechanism from the rear rod end while the front rod clamps, leveraging the 463 kgf max output for synchronous dual-action tooling.
Is the Airtac SED Double Rod Cylinder SED80X75S the Right Cylinder?
Choose this 80 mm bore when an application requires 2268 N of both-way thrust at 0.5 MPa. If your load is lighter, the 63 mm bore provides 1402 N both ways; for heavier drives, stepping up to the 100 mm bore yields 3681 N. The twin-rod design inherently resists torsional rotation, making it superior to a single-rod SE cylinder for guiding loads or mounting rear-rod tooling.
To replace an existing ISO 15552 unit, match the 75 mm stroke, PT3/8 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that a plain SED drifts on air loss—the cushions decelerate but do not lock. For fail-safe holding, specify a BSED or external lock. The 25 mm rod handles high side loads, though external guides are always recommended for optimal bearing life.
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 SED80X75S FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It provides 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and a maximum of 463 kgf at 1.0 MPa.
The twin-rod design provides identical extend and retract forces, better resistance to torsional side loads, and allows you to mount rear-rod tooling or sensors. It is dimensionally interchangeable with other ISO 15552 profile cylinders, but requires rear-rod clearance.
