Airtac SED Double Rod Cylinder SED80X500
The AirTAC Airtac SED Double Rod Cylinder SED80X500 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 500mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X500
The AirTAC SED80X500 is a double-acting, double-rod ISO 15552 profile cylinder engineered for balanced load handling. Because a 25mm rod exits both end covers, the annulus area is identical on extend and retract. This generates equal force in both directions, delivering 2268 N at 0.5 MPa and 3175 N at 0.7 MPa. The extruded aluminum barrel contains no external tie rods, ensuring clean integration.
This 500mm stroke unit features field-adjustable air cushioning at both ends to manage end-of-stroke kinetic energy. Note that this specific SKU lacks the -S magnet option, meaning it cannot host CMSE reed or DMSE electronic position sensors without modification. You must also account for rear-rod protrusion in your layout, as the twin-rod design extends overall length beyond a standard single-rod SE cylinder.

| 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 |

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 SED80X500 Is Used
PCB Panel Lifters
Drives vertical lifting stages in PCB handling machines. The 2268 N both-way force securely elevates heavy panel racks, while the twin rods prevent chassis binding across the 500mm travel.
Dual-Action Indexing
Powers a dual-station indexing mechanism where the rear rod actuates a secondary pneumatic valve. Equal push and pull forces ensure consistent timing on both ends of the 500mm cycle.
Pallet Transfer Gates
Diverts heavy pallets on packaging conveyors. The 3175 N output at 0.7 MPa handles high friction loads, and the rigid 25mm twin rods absorb torsional stress during lateral deflection.
Is the Airtac SED Double Rod Cylinder SED80X500 the Right Cylinder?
When sizing this 80mm bore, consider the neighboring bores. Stepping down to a 63mm bore yields 1402 N at 0.5 MPa both ways, while stepping up to a 100mm bore provides 3681 N. Choose this double-rod SED over a single-rod SE when your mechanism requires high resistance to torsion, dual-side guidance, or a rear rod end to drive a secondary cam. The twin 25mm rods significantly improve anti-rotation stability for heavy loads.
Because this model has a 500mm stroke, external guide rails are strongly recommended to prevent side-loading damage to the rod seals. For ISO 15552 replacement, verify the 500mm stroke, PT3/8 port, and preferred mounting (Basic, FA, LB, TC, FTC, TCM1, or TCM2). If your process cannot tolerate drift upon air loss, note that standard air cushions only decelerate near stroke end; a BSED double-rod rod lock or external pilot check valve is required for fail-safe position holding.
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 SED80X500 FAQ
Because the double-rod design occupies piston area on both sides, 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.
Yes, it is dimensionally interchangeable per ISO 15552 / VDMA 24562. Just verify your mounting style is supported (Basic, FA, LB, TC, FTC, TCM1, TCM2) and ensure you leave rear-rod clearance, as the double-rod design increases overall length compared to a single-rod cylinder.
