Airtac SED Double Rod Cylinder SED80X185S
The AirTAC Airtac SED Double Rod Cylinder SED80X185S 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 185mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X185S
The AirTAC SED80X185S is a double-acting, double-rod ISO 15552 profile cylinder. A Ø25 mm rod exits both end covers, yielding identical annulus areas and equal force in extend and retract—delivering 2268 N each way at 0.5 MPa. The extruded aluminum barrel avoids external tie rods for a clean profile.
This 80 mm bore unit includes the -S magnet for position sensing via CMSE reed or DMSE electronic switches. Field-adjustable air cushions at both ends decelerate the 185 mm stroke, while the rear rod extension can drive a secondary mechanism or carry a limit flag.
Airtac SED Double Rod Cylinder SED80X185S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED80X185S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 185 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 SED80X185S Is Used
Web Guiding Brakes
Applies 3175 N of equal both-way clamping force to tension film or paper webs, using the twin rods to prevent rotational drift during high-speed directional shifts.
Dual-Side Shuttle Drive
Transfers PCB cassettes between process bays by driving a fixture from the front rod while the rear rod simultaneously trips a remote mechanical flag.
Centering Press Jaws
Squeezes aluminum housings with matched opposing force, leveraging the symmetrical 2268 N thrust at 0.5 MPa to center parts without yawing before a crimping operation.
Is the Airtac SED Double Rod Cylinder SED80X185S the Right Cylinder?
Step down to the 63 mm bore (1402 N at 0.5 MPa) for lighter loads, or up to the 100 mm bore (3681 N at 0.5 MPa) if you need more thrust. Choose this double-rod SED over a single-rod SE when your application demands anti-rotation guidance, twin-side load driving, or rear-rod tooling.
To replace an ISO 15552 cylinder, match the 80 mm bore, 185 mm stroke, PT3/8 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2—note FB/CA/CB/CR are omitted). The adjustable cushion only decelerates near stroke end; it will not hold position on air loss. For fail-safe holding, use a BSED double-rod rod lock or external pilot 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 SED80X185S FAQ
Because the double-rod design has equal piston areas on both sides, force is identical in both directions: 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and a maximum of 463 kgf at 1.0 MPa.
A rod exits both ends, providing better load guidance against rotation and allowing the rear rod to drive a secondary mechanism or sensor cam. It drops into standard ISO 15552 mounting dimensions but requires rear-rod clearance.
