Airtac SED Double Rod Cylinder SED80X100S
The AirTAC Airtac SED Double Rod Cylinder SED80X100S 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 100mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X100S
The AirTAC SED80X100S is a double-acting, double-rod profile cylinder fully dimensionally interchangeable per ISO 15552. Because a 25mm rod exits both end covers, the annulus area is identical on extend and retract, yielding an equal 2268N of thrust and pull at 0.5MPa. The extruded aluminum barrel contains no external tie rods, providing a clean profile that drops in for any ISO 15552 double-rod footprint.
Equipped with a standard -S magnet, this unit interfaces directly with CMSE reed and DMSE electronic sensors. The rear rod end can mount a cam or limit flag to trigger these sensors, or even drive a secondary mechanism. Field-adjustable air cushions at both ends decelerate the load near stroke end, while the PT3/8 ports supply air to both chambers.

| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 100 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 SED80X100S Is Used
Web Guiding Press
Uses the 2268N equal both-way force to crease and align heavy paper or foil webs, relying on the twin rods to prevent chassis rotation during rapid reversals.
Dual-Lane Transfer
Drives two parallel conveyor pusher arms simultaneously from one 80mm piston, utilizing the rear rod output to maintain perfectly synchronized lane sorting.
Indexing Cam Drive
Mounts a cam on the rear rod end to trigger DMSE electronic sensors mid-stroke, sequencing a multi-stage CNC machining clamp without external actuators.
Is the Airtac SED Double Rod Cylinder SED80X100S the Right Cylinder?
When sizing this 80mm bore, step down to the 63mm bore for 1402N of equal both-way force at 0.5MPa, or step up to the 100mm bore for 3681N if your payload requires more thrust. Choose this double-rod SED over a single-rod SE when your application demands superior anti-rotation guidance, the ability to drive twin loads simultaneously, or rear-rod sensing. At 100mm stroke, side loading is moderate, but external guides remain recommended for optimal bearing life.
To replace an existing ISO 15552 cylinder, match the 80mm bore, 100mm stroke, PT3/8 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Remember that a plain SED does not hold position on air loss; the piston drifts. The adjustable cushion decelerates but does not lock. For fail-safe holding, specify a BSED double-rod rod lock or an external pilot-operated 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 SED80X100S FAQ
Because the double-rod design subtracts the 25mm rod area on both sides, force is identical in both directions: 2268N at 0.5MPa, 3175N at 0.7MPa, and a maximum of 463kgf at 1.0MPa.
The twin-rod design provides equal extend and retract forces, superior anti-rotation stability for guided loads, and a rear rod end that can mount tooling or sensor flags. It maintains a true ISO 15552 mounting interface but omits FB, CA, CB, and CR mounting styles.
