Airtac SED Double Rod Cylinder SED32X135S
The AirTAC Airtac SED Double Rod Cylinder SED32X135S 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 135mm, PT1/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED32X135S
The AirTAC SED32X135S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensions. Because a 12mm rod exits both ends, the annular piston area is identical on extend and retract, yielding a true equal force of 345 N each way at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, ensuring a clean profile that drops directly into standard ISO 15552 mounting interfaces.
Fitted with the -S magnet option, this unit supports CMSE reed and DMSE electronic sensors in the integrated barrel groove. Field-adjustable air cushions at both ends (27mm cushion length) manage end-of-stroke energy, while the rear rod end provides a second mounting point for tooling, a cam, or a limit flag without needing extra space.

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø32 mm |
| Stroke | 135 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 SED32X135S Is Used
Pick-and-Place Grippers
The 345 N equal both-way force is perfect for compact grippers that clamp and release parts, using the rear rod to trigger a CMSE sensor for cycle confirmation.
Synchronized Transfer Arms
Leverage the twin 12mm rods to drive two synchronized pick-off arms from one cylinder, ensuring parallel part ejection without torsional deflection.
Web Edge Guiding
The anti-rotation properties of the double-rod design keep the guide roller perfectly aligned, providing stable lateral correction for moving webs.
Is the Airtac SED Double Rod Cylinder SED32X135S the Right Cylinder?
Choose this 32mm bore when you need compact 345 N bi-directional force. If your application requires less push, there is no smaller SED bore, but if you need more force, stepping up to the 40mm bore yields 528 N each way at 0.5 MPa. The twin-rod design inherently resists torsional load and provides superior anti-rotation guidance compared to a single-rod SE cylinder, making it ideal for moving a load on one side while driving a secondary mechanism off the rear rod.
At 135mm stroke, the 12mm rod protrudes from both end covers, so verify your rear-rod clearance. To replace an existing ISO 15552 cylinder, match the 32mm bore, 135mm stroke, PT1/8 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Remember that the air cushion only decelerates near stroke end; it does not hold position on air loss. For fail-safe holding, use an external rod lock or 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 SED32X135S FAQ
Because the double-rod design has equal piston area on both sides, it provides 345 N of force at 0.5 MPa and 483 N at 0.7 MPa in both directions. The maximum force is 70 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per ISO 15552. Just match the 32mm bore, 135mm stroke, PT1/8 port, and mounting style. Note that SED omits FB, CA, CB, and CR mounts, offering only Basic, FA, LB, TC, FTC, TCM1, and TCM2.
