Airtac SED Double Rod Cylinder SED80X110S
The AirTAC Airtac SED Double Rod Cylinder SED80X110S 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 110mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X110S
The AirTAC SED80X110S is a double-acting, double-rod profile cylinder dimensionally interchangeable per ISO 15552. Because a Ø25 mm rod exits both end covers, the annulus area is identical on extend and retract, yielding a perfectly symmetrical 2268 N of thrust and pull at 0.5 MPa.
Equipped with the -S magnet option, this unit supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. The extruded aluminum barrel omits external tie rods, and the field-adjustable air cushioning at both ends decelerates the 110 mm stroke without acting as a position lock.
Airtac SED Double Rod Cylinder SED80X110S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED80X110S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 110 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 SED80X110S Is Used
Web Guiding Press
Provides 2268 N of perfectly equal push/pull force to keep a paper web tracking straight without rotational skew during 110 mm edge adjustments.
Dual-Side Shuttle
Uses the twin M20x1.5 rod ends to drive two opposing packaging jaws simultaneously, ensuring they meet perfectly centered every cycle.
Rear-Cam Actuation
Leverages the protruding rear rod to trip a mechanical limit valve on a CNC loader, operating independently of the front 3175 N tool thrust.
Is the Airtac SED Double Rod Cylinder SED80X110S the Right Cylinder?
Select this 80 mm bore when your mechanism requires 2268 N both ways at 0.5 MPa, stepping down from the 100 mm bore (3681 N) if you need to reduce physical envelope, or up from the 63 mm bore (1402 N) when the smaller annulus cannot move your mass. The twin rods provide superior anti-rotation resistance compared to a single-rod SE cylinder, and the rear protrusion can mount a secondary cam or limit flag.
To replace an ISO 15552 unit, match the 110 mm stroke, PT3/8 port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2—omitting FB/CA/CB/CR). Note that a plain SED drifts on air loss; for fail-safe holding, specify a BSED rod-lock cylinder or an external brake. For this 110 mm stroke, standard bearing support handles side loads adequately, but always verify guide alignment.
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 SED80X110S FAQ
Because the double-rod design has equal piston area on both sides, it generates 2268 N at 0.5 MPa and 3175 N at 0.7 MPa in both directions, with a maximum of 463 kgf at 1.0 MPa.
The twin-rod layout guarantees equal force and speed on extend and retract, offers better load guidance against rotation, and provides a rear rod end for secondary cams or sensors while maintaining a true ISO 15552 mounting interface.
