Airtac SED Double Rod Cylinder SED32X120S
The AirTAC Airtac SED Double Rod Cylinder SED32X120S 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 120mm, PT1/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED32X120S
The AirTAC SED32X120S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a 12mm rod exits both end covers, the effective piston area is identical on extend and retract. This gives you exactly 345 N of output force in both directions at 0.5 MPa.
The integrated -S magnet supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. You can also mount a cam or flag on the rear rod end to trigger external limits, while the twin-rod geometry resists torsional twist better than a single-rod SE cylinder.

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø32 mm |
| Stroke | 120 mm |
| Configuration | Double rod, double acting |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| 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, 27 mm |
| Max stroke | Up to 1000 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 (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 SED32X120S Is Used
PCB Depanelling Saw
Drives a cutting blade on the front rod while the rear rod carries a sync flag, using the 345 N both-way force to cleanly slice populated boards.
Label Feed Spindle
Uses the twin-rod anti-rotation property to guide a precision label roller, preventing angular drift during high-speed 30-800 mm/s indexing.
Lab Sample Ejector
Pushes a test tray out with the front rod while the rear rod actuates a limit switch, relying on equal 483 N force at 0.7 MPa for reliable ejection.
Is the Airtac SED Double Rod Cylinder SED32X120S the Right Cylinder?
Step down to a smaller bore if your load requires less than 345 N, or step up to the 40mm bore (528 N at 0.5 MPa) if you need more thrust. This 32mm bore provides 483 N at 0.7 MPa. Choose this double-rod format over a single-rod SE when you need anti-rotation guidance, dual-side load driving, or rear-rod tooling.
Remember that a plain SED does not hold position on air loss; the piston drifts, and the adjustable air cushion only decelerates near stroke end. For fail-safe holding, use a BSED rod lock or external check valve. For ISO 15552 drop-in replacement, match the 32mm bore, 120mm stroke, PT1/8 port, and preferred mounting (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
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 SED32X120S FAQ
Because the rod occupies both sides of the piston, force is equal in both directions: 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 resistance and allows the rear rod end to drive a secondary mechanism or sensor cam. It also ensures the output force remains identical on extend and retract.
