Airtac SED Double Rod Cylinder SED80X90
The AirTAC Airtac SED Double Rod Cylinder SED80X90 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 90mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X90
The AirTAC SED80X90 is a double-acting, double-rod profile cylinder built to ISO 15552 dimensions. A 25mm rod exits both end covers, yielding 2268 N of force in both extend and retract directions at 0.5 MPa. The extruded aluminum barrel omits external tie rods, and field-adjustable air cushions at both ends manage deceleration over the 36mm cushion length.
Because the rear piston side carries a rod, annular areas match perfectly, ensuring equal thrust and speed both ways. This unit lacks the -S magnet option, so it cannot host CMSE or DMSE position sensors directly on the body. The PT3/8 port feeds the chamber, while the protruding rear rod can mount a cam or secondary tooling.
Airtac SED Double Rod Cylinder SED80X90 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED80X90 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 90 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 SED80X90 Is Used
Multi-Station Indexing Mill
Drives a 2268 N indexing carriage between machining stations, using the rear rod to trip external mechanical flags without needing body sensors.
Glass Panel Transfer
Pushes and retracts suction cups with equal 0.5 MPa force both ways, preventing asymmetric acceleration that could drop fragile panes.
Web Guiding Mechanism
Employs the twin 25mm rods to resist rotational torque during high-speed web positioning, maintaining alignment without external guides.
Is the Airtac SED Double Rod Cylinder SED80X90 the Right Cylinder?
Select this 80mm bore when an application requires 2268 N both ways at 0.5 MPa. If you need less force, the 63mm bore provides 1402 N both ways. If you need more, the 100mm bore yields 3681 N both ways. Choose this double-rod SED over a single-rod SE when you need superior anti-rotation guidance, dual-side tooling, or a rear cam for external limit switches. Verify your ISO 15552 mounting interface needs, as SED supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, CR). Remember that a plain SED does not hold position on air loss; the piston drifts, and the cushion only decelerates near stroke end. For fail-safe holding, use a BSED or 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 SED80X90 FAQ
The SED80X90 delivers equal force in both directions due to the double-rod design: 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 profile standards. Just match the 80mm bore, 90mm stroke, PT3/8 port, and mounting style. Note that overall length is longer than a single-rod SE to accommodate the rear rod.
