Airtac SED Double Rod Cylinder SED80X700
The AirTAC Airtac SED Double Rod Cylinder SED80X700 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 700mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X700
The AirTAC SED80X700 is a double-acting, double-rod profile cylinder fully dimensionally interchangeable per ISO 15552. Because a 25mm rod occupies both sides of the 80mm piston, the effective annulus area is identical in both directions, yielding an equal 2268 N of drive force at 0.5 MPa on extend and retract.
This unit lacks the -S magnet option, meaning no CMSE or DMSE position sensing is installed on this SKU. The extruded aluminum barrel incorporates field-adjustable air cushioning (36mm stroke length) at both ends to decelerate the payload near stroke limits, and the PT3/8 ports use the default tapered thread form.
Airtac SED Double Rod Cylinder SED80X700 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED80X700 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 700 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 SED80X700 Is Used
CNC Lathe Loader
Drives a bar feeder pusher into the spindle, using the 2268 N both-way force and rear rod to mount a synchronized limit flag without torsional deflection.
Pallet Transfer Gate
Diverts heavy pallets across a 700mm stroke, relying on the twin-rod anti-rotation design to keep the diverting head perfectly parallel under high inertia.
Textile Calender Press
Applies equal clamping tension in both directions on a fabric roller, utilizing the ISO 15552 footprint to drop-in replace a worn profile cylinder.
Is the Airtac SED Double Rod Cylinder SED80X700 the Right Cylinder?
At 0.5 MPa, this 80mm bore yields 2268 N both ways. If your payload is lighter, the 63mm bore provides 1402 N; if you need more push, the 100mm bore offers 3681 N. Choose this double-rod SED over a single-rod SE when a machine requires dual-side guidance, anti-rotation stability, or a rear-rod extension to mount a secondary cam or tooling.
For any stroke length of 700mm, external guide rails are strongly recommended to prevent side loads from bending the extended 25mm rods. Remember that a plain SED does not hold position on air loss—the piston drifts, and the adjustable cushion is not a brake. For fail-safe holding, select a BSED double-rod lock or an external rod lock.
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 SED80X700 FAQ
The SED80X700 provides equal force in both extend and retract directions due to the double-rod design. It outputs 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. You can drop-in replace any ISO 15552 double-rod unit matching the 80mm bore, 700mm stroke, PT3/8 port, and mounting interface (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
