Airtac SED Double Rod Cylinder SED80X180S
The AirTAC Airtac SED Double Rod Cylinder SED80X180S 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 180mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X180S
The AirTAC SED80X180S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. A 25 mm rod extends from both end covers, yielding identical annulus areas. This means output force is perfectly balanced at 2268 N in both extend and retract directions at 0.5 MPa.
Equipped with a -S magnet, the unit supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. The extruded aluminum barrel omits external tie rods, and field-adjustable air cushions at both ends absorb kinetic energy near stroke limits.

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 180 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 |

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 SED80X180S Is Used
Servo Press Platen Drive
Drives a stamping platen with 2268 N of equal force both ways, using the twin 25 mm rods to keep the tooling perfectly parallel during heavy sheet-metal forming.
Dual-Side Pallet Transfer
Pushes and retracts pallets on an automated packaging line, utilizing the rear rod extension to trip a mechanical limit flag for sequencing confirmation.
PCB Handling Lift Gate
Actuates a lifting gate in electronics assembly, relying on the anti-rotation properties of the double-rod design to prevent binding during 180 mm vertical travel.
Is the Airtac SED Double Rod Cylinder SED80X180S the Right Cylinder?
Select this 80 mm bore when your application requires 2268 N of bidirectional force at 0.5 MPa. If your load is lighter, the 63 mm bore provides 1402 N both ways; for heavier drives, stepping up to the 100 mm bore yields 3681 N. The twin-rod design inherently resists torsional rotation, making it superior to a single-rod SE cylinder for guiding heavy loads.
This SED80X180S carries a PT3/8 port and a 180 mm stroke. At this stroke length, ensure external linear guides support the load to prevent side-loading on the rod seals. Note that a plain SED drifts on air loss—the cushions decelerate but do not lock position. For fail-safe holding, use an external rod lock or a BSED double-rod rod-lock cylinder. To replace an existing ISO 15552 unit, match the 80 mm bore, 180 mm stroke, mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2), and magnet option.
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 SED80X180S FAQ
Because the double-rod design balances the piston area, 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.
The twin rods provide superior anti-rotation guidance and allow the rear rod to drive a secondary mechanism or sensor flag. It drops into any ISO 15552 footprint using Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts, but requires rear-rod clearance due to its longer overall length.
