Airtac SED Double Rod Cylinder SED80X900
The AirTAC Airtac SED Double Rod Cylinder SED80X900 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 900mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X900
The AirTAC SED80X900 is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a rod exits both ends, the annulus area is symmetrical, yielding equal force in both directions at 2268 N (0.5 MPa). The extruded aluminum barrel omits external tie rods for a clean profile.
This 900mm stroke unit features a 25mm carbon steel rod, M20x1.5 threading, and PT3/8 ports. Adjustable air cushions at both ends manage kinetic energy. Note this SKU lacks a piston magnet, so it does not support CMSE or DMSE position sensors.
Airtac SED Double Rod Cylinder SED80X900 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED80X900 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 900 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 SED80X900 Is Used
Pallet Transfer Reject
Uses the 2268 N both-way force to push heavy pallets off a high-speed conveyor line, with the rear rod driving a synchronized diverter cam.
Textile Beam Indexing
Shifts heavy textile beams laterally between processing stations, relying on the twin rods to prevent rotational sag over the 900mm extension.
Multi-Head Drill Feed
Drives a dual-sided drilling fixture where the opposing rod end simultaneously triggers a limit flag for stroke confirmation.
Is the Airtac SED Double Rod Cylinder SED80X900 the Right Cylinder?
Step down to the 63mm bore for 1402 N, or up to the 100mm bore for 3681 N (both at 0.5 MPa, both directions). Choose this 80mm double-rod over a single-rod SE when you need anti-rotation guidance, a rear rod for cam actuation, or dual-side tooling. At 900mm, side loading is a major risk; use external linear guides to prevent binding.
A plain SED cannot hold position on air loss; the piston drifts. The adjustable cushion only decelerates near end-of-stroke. For fail-safe holding, use a BSED double-rod lock. To replace an ISO 15552 unit, match the 80mm bore, 900mm stroke, PT3/8 port, and mounting (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SED80X900 FAQ
Because it is a double-rod cylinder, 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. The SED80X900 is an ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 double-rod units. Just match the mounting style (Basic, FA, LB, TC, FTC, TCM1, TCM2) and ensure you leave clearance for the rear rod.
