Airtac SED Double Rod Cylinder SED32X70S
The AirTAC Airtac SED Double Rod Cylinder SED32X70S is a genuine double-acting ISO 15552 double-rod cylinder: a Ø12mm piston rod exits BOTH ends of the Ø32mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 70mm, PT1/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED32X70S
The AirTAC SED32X70S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and 70mm stroke. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding equal force and speed in both directions. You get 345 N of output each way at 0.5 MPa. The extruded aluminum barrel has no external tie rods, providing a clean profile that drops in dimensionally for any ISO 15552 footprint.
Equipped with a standard magnet (-S), this unit supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. The rear rod end can mount a cam or sensor flag to trigger secondary operations, while the twin-rod design inherently resists torsion and guides loads against rotation better than a single rod. Adjustable air cushions at both ends absorb kinetic energy near stroke end.

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 (Ø32mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 346 N |
| 0.7 MPa | 484 N |
| Max (@1.0 MPa) | 70 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 SED32X70S Is Used
PCB Depaneling Saw
Drives a cutting head with 345 N of equal bidirectional force, using the rear rod to trigger a cam-actuated dust extraction hood.
Pick-and-Place Transfer
Moves small electronic components between conveyor belts, relying on the twin rods to prevent gripper rotation during rapid 70mm shifts.
Lab Dispenser Indexing
Actuates a metering valve where equal extend and retract speeds ensure consistent fluid dosing without pressure spikes.
Is the Airtac SED Double Rod Cylinder SED32X70S the Right Cylinder?
Choose this 32mm bore when you need 345 N of bidirectional force at 0.5 MPa. If your application requires less push, step down to the next available bore, but if you need greater thrust, step up to the 40mm bore which provides 528 N both ways at 0.5 MPa. The twin-rod architecture suits applications needing anti-rotation stability, rear-rod tooling, or dual-side actuation. For a direct ISO 15552 replacement, match the 32mm bore, 70mm stroke, PT1/8 port, and your required mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that FB, CA, CB, and CR mounts are omitted from this series.
A plain SED does not hold position upon air loss; the piston will drift. The adjustable air cushion decelerates the load near stroke ends but does not act as a locking brake. For fail-safe holding, consider a BSED double-rod rod lock cylinder 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 SED32X70S FAQ
Because the rod occupies both sides of the piston, force is equal in both directions. It provides 345 N at 0.5 MPa, 483 N at 0.7 MPa, and a maximum of 70 kgf at 1.0 MPa.
The twin-rod design provides superior anti-rotation guidance for the load and allows the rear rod end to drive a secondary mechanism or sensor flag. It also ensures speed and force are perfectly matched on extend and retract.
