Airtac SED Double Rod Cylinder SED80X165S
The AirTAC Airtac SED Double Rod Cylinder SED80X165S 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 165mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X165S
The AirTAC SED80X165S is a double-acting, double-rod ISO 15552 profile cylinder. A 25mm rod exits both end covers, yielding an identical annulus area on both sides. This means you get 2268 N of force in both extend and retract directions at 0.5 MPa. The extruded aluminum barrel includes sensor grooves, and this -S variant includes a magnet for CMSE reed or DMSE electronic sensors.
Because a piston rod protrudes from the rear cover, overall length is longer than a single-rod SE cylinder, requiring rear-rod clearance. The rear extension can drive a secondary mechanism or mount a cam. It features field-adjustable air cushioning at both ends (36mm cushion length) to decelerate the load near stroke end. Thread form is default PT3/8.

| 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 SED80X165S Is Used
Servo Press Transfer
Drives a press transfer arm with 2268 N both ways. The rear rod mounts a cam to trigger a sequential valve, while the twin rods prevent chassis rotation under off-center loads.
Pallet Diverting Gate
Shifts heavy pallets transversely using the 3175 N available at 0.7 MPa. The through-rod design allows a flag to trip a DMSE electronic sensor at the exact mid-stroke position.
Textile Calendering
Applies uniform tensioning to fabric rollers. Because the effective piston area is identical both ways, the 80mm bore delivers perfectly symmetrical clamping without pressure spikes.
Is the Airtac SED Double Rod Cylinder SED80X165S the Right Cylinder?
Select this 80mm bore when you need 2268 N both ways at 0.5 MPa. If you need less force, step down to the 63mm bore providing 1402 N. If your application demands more power, step up to the 100mm bore yielding 3681 N. The twin-rod design is superior to a single-rod SE cylinder when you need anti-rotation guidance or must drive a load from both ends simultaneously.
This cylinder uses an ISO 15552 mounting interface (Basic, FA, LB, TC, FTC, TCM1, TCM2; it omits FB/CA/CB/CR). Note that the adjustable air cushion only decelerates near stroke end; it is not a brake. A plain SED does not hold position on air loss—the piston drifts. For fail-safe holding, use a BSED double-rod rod lock or an external pilot-operated check valve. Since the stroke is 165mm, ensure external guides support any heavy lateral loads.
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 SED80X165S FAQ
The SED80X165S delivers equal force in both directions because a rod occupies both sides of the piston. 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.
The twin-rod design provides identical force and speed on extend and retract, and offers better load guidance against rotation. The protruding rear rod can also drive a secondary mechanism or mount a sensor flag, which a single-rod SE cannot do.
