Airtac SED Double Rod Cylinder SED80X75
The AirTAC Airtac SED Double Rod Cylinder SED80X75 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 SED80X75
The AirTAC SED80X75 is a double-acting, double-rod ISO 15552 profile cylinder. A Ø25 mm rod exits both end covers, yielding identical annulus areas. This design outputs 2268 N of thrust and pull force at 0.5 MPa, making it perfectly balanced for demanding push-pull cycles.
Because a rear rod protrudes past the back cover, you can mount a secondary cam or sensor flag directly on it. The extruded aluminum barrel lacks external tie rods, and this specific SKU ships without a magnet (-S), meaning no CMSE or DMSE electronic position sensing is installed. Field-adjustable air cushioning at both ends decelerates the 30-800 mm/s motion near stroke ends.

|---|---|
| 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 SED80X75 Is Used
Servo-Press Ejection
Drives a multi-stage stamping ejector. The twin rods prevent binding under off-center loads, delivering the full 2268 N both-ways force at 0.5 MPa for reliable part extraction.
Pallet Transfer Gate
Actuates a diverter gate on a packaging conveyor. The rear rod end mounts a mechanical cam to trigger a downstream sensor, utilizing the 3175 N capacity at 0.7 MPa.
Web Edge Guiding
Steers a heavy textile web edge guide system. The double-rod configuration provides high torsional stiffness against material pull, ensuring precise tracking without rotational deflection.
Is the Airtac SED Double Rod Cylinder SED80X75 the Right Cylinder?
At 0.5 MPa, this 80 mm bore generates 2268 N of force equally in both directions. If your application requires less force, step down to the 63 mm bore providing 1402 N both ways. If you need more power, the 100 mm bore offers 3681 N at the same pressure. Choose this twin-rod SED over a single-rod SE when your machine demands anti-rotation guidance, dual-side load driving, or rear-rod tooling integration.
Remember that a standard SED does not hold position on air loss; the piston will drift. For fail-safe holding, consider a BSED double-rod rod lock or an external pilot-operated check valve. When replacing an ISO 15552 cylinder, verify the 75 mm stroke, PT3/8 port, and mounting style. SED supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, intentionally omitting FB, CA, CB, and CR.
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 SED80X75 FAQ
Because the double-rod design creates equal piston areas on both sides, force is identical in extend and retract. It provides 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and a maximum of 463 kgf at 1.0 MPa.
A double-rod SED provides equal force and speed in both directions, better load guidance against rotation, and a rear rod end that can mount tooling or a sensor flag. It is dimensionally interchangeable with other ISO 15552 double-rod cylinders.
