Airtac SED Double Rod Cylinder SED32X120
The AirTAC Airtac SED Double Rod Cylinder SED32X120 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 SED32X120
The AirTAC SED32X120 is a double-acting, double-rod profile cylinder operating on the ISO 15552 interface. Because a 12mm rod exits both end covers, the effective piston area is identical in both directions, yielding a balanced 345 N of thrust and pull at 0.5 MPa.
This twin-rod layout excels at driving dual mechanisms or mounting a rear cam for position feedback. Note this specific SKU lacks a piston magnet, so it cannot host CMSE or DMSE sensors without modification. It features adjustable air cushioning at both ends over a 27mm stroke length.
Airtac SED Double Rod Cylinder SED32X120 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED32X120 |
|---|---|
| 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 SED32X120 Is Used
PCB Depaneling Saw
Drives a circular blade forward and retracts it at identical 345 N speeds, utilizing the rear rod to push a synchronized dust extraction hood.
Wire Straightener
Feeds copper wire through a die; the twin 12mm rods prevent rotational twist during the 120mm extend cycle, ensuring flat wire output.
Gripper Jaw Actuator
Powers an opposing parallel gripper where equal 483 N force at 0.7 MPa is required on both the clamping and release strokes.
Is the Airtac SED Double Rod Cylinder SED32X120 the Right Cylinder?
Select this 32mm bore when you need 345 N of perfectly symmetrical force across a 120mm stroke. If your project requires less push, there is no smaller SED bore, but if you need more power, stepping up to the 40mm bore provides 528 N both ways at 0.5 MPa. Since the stroke exceeds 100mm, ensure external guides support the load to prevent side-loading on the 12mm rods.
This cylinder is a drop-in replacement for any ISO 15552 double-rod unit matching its PT1/8 port, M10x1.25 rod thread, and Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings (note the omission of FB/CA/CB/CR variants). Remember that a standard SED does not hold position upon air loss; for fail-safe locking, specify a BSED series cylinder.
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 SED32X120 FAQ
Because the double-rod design subtracts the rod area on both sides, 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.
Yes. The SED32X120 is dimensionally interchangeable per ISO 15552 / VDMA 24562. Just match the 32mm bore, 120mm stroke, PT1/8 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
