Airtac SED Double Rod Cylinder SED80X105
The AirTAC Airtac SED Double Rod Cylinder SED80X105 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 105mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X105
The AirTAC SED80X105 is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a 25mm rod exits both end covers, the annulus area is balanced. It generates 2268 N of output force in both extend and retract directions at 0.5 MPa. The extruded aluminum barrel has no external tie rods, ensuring a clean profile that drops in for any ISO 15552 footprint.
This configuration uses a PT3/8 port and a 36mm adjustable air cushion at both ends to manage kinetic energy near stroke limits. Note this SKU omits the magnet option, meaning no CMSE or DMSE position sensing is installed. The rear rod extension is ideal for mounting a cam or driving a secondary mechanism, while simultaneously improving load guidance against rotation.
Airtac SED Double Rod Cylinder SED80X105 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED80X105 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 105 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 SED80X105 Is Used
Servo Press Sub-presses
Drives secondary sub-press tooling with 2268 N of equal both-way force, using the rear rod to trigger a mechanical limit flag without twisting the main assembly.
Pallet Diverters
Actuates heavy conveyor diverting arms where the twin 25mm rods prevent binding during high-speed 30-800 mm/s pallet routing shifts.
Glass Edge Square-up
Squaring heavy glass panels on a processing line; the dual-rod geometry resists yawing under offset loads while pushing and pulling with identical 2268 N force.
Is the Airtac SED Double Rod Cylinder SED80X105 the Right Cylinder?
Select this 80mm bore when you need 2268 N of equal bidirectional force at 0.5 MPa. If your application is lighter, the adjacent 63mm bore provides 1402 N both ways. For heavier drives, stepping up to the 125mm bore yields 5734 N. Choose this double-rod SED over a single-rod SE when the mechanism requires twin-side load guidance, anti-rotation stability, or rear-rod tooling. To match an existing ISO 15552 cylinder, verify the 105mm stroke, PT3/8 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
Remember that a plain SED does not hold position on air loss; the piston will drift. The adjustable air cushion only decelerates the load near the stroke end, acting as a brake rather than a lock. For fail-safe holding, consider a BSED double-rod rod lock or an external pilot-operated check valve.
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 SED80X105 FAQ
The SED80X105 provides equal force in both directions due to the double-rod design. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and reaches a maximum of 463 kgf at 1.0 MPa.
Yes. The SED80X105 is a profile cylinder dimensionally interchangeable per ISO 15552 / VDMA 24562. You can drop it in by matching the 80mm bore, 105mm stroke, PT3/8 port, and mounting hardware. Note that the overall length is longer than a single-rod cylinder to accommodate the rear rod.
