Airtac SED Double Rod Cylinder SED32X185
The AirTAC Airtac SED Double Rod Cylinder SED32X185 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 185mm, PT1/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED32X185
The AirTAC SED32X185 is a double-acting, double-rod ISO 15552 profile cylinder. Because a 12mm rod exits both end covers, the effective piston area is identical in both directions. This generates an equal push and pull force of 345N at 0.5 MPa, ensuring perfectly balanced motion for 185mm of travel.
This 32mm bore unit features a PT1/8 port and field-adjustable air cushioning at both ends to manage end-of-stroke impacts. This specific SKU lacks the -S magnet option, meaning it has no integrated position sensing out of the box. The extruded aluminum barrel design omits external tie rods entirely.
Airtac SED Double Rod Cylinder SED32X185 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED32X185 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø32 mm |
| Stroke | 185 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 SED32X185 Is Used
PCB Edge Trimming
Drives a cutting head on an automated PCB depaneling router. The twin rods prevent blade deflection during the 185mm cutting pass, utilizing the 345N both-way force for smooth advance and retract.
Shuttle Transfer Gate
Actuates a sliding transfer gate between two conveyor lanes. The equal both-way force ensures the gate moves at consistent speeds whether opening or closing, without requiring flow controls.
Pick-and-Place Cam
Uses the rear rod end to drive a mechanical cam for a secondary gripper action. The 32mm bore provides compact 345N actuation while the front rod handles the main vertical pick-and-place lift.
Is the Airtac SED Double Rod Cylinder SED32X185 the Right Cylinder?
If your application requires less force, the adjacent 32mm bore is the smallest available in this series, so stepping up to the 40mm bore provides 528N at 0.5 MPa. If 345N is sufficient, this model is ideal. Choose this double-rod SED over a single-rod SE when you need to prevent load rotation, mount a rear cam, or drive two mechanisms simultaneously from one cylinder. Remember that a plain SED will drift on air loss; for fail-safe holding, use a BSED double-rod lock cylinder. As an ISO 15552 drop-in replacement, verify your bore, 185mm stroke, PT1/8 port, and mounting interface (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 SED32X185 FAQ
Because the double-rod design has a rod on both sides of the piston, the force is equal in both directions. It provides 345N at 0.5 MPa, 483N at 0.7 MPa, and a maximum of 70 kgf at 1.0 MPa.
Yes, the SED32X185 is dimensionally interchangeable per ISO 15552 / VDMA 24562. Just ensure your mounting matches the available SED set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and you have rear-rod clearance for the protruding 12mm rod.
