Airtac SED Double Rod Cylinder SED32X85
The AirTAC Airtac SED Double Rod Cylinder SED32X85 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 85mm, PT1/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED32X85
The AirTAC SED32X85 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and 85mm stroke. Because a 12mm rod occupies both piston sides, the annulus area is identical in both directions, yielding an equal drive force of 345N at 0.5MPa on extend and retract. The extruded aluminum barrel contains no external tie rods, ensuring a clean profile that drops in dimensionally for any ISO 15552 mounting interface.
This unit lacks the -S magnet option, so it has no onboard position sensing on this SKU. The rear rod extension can drive a secondary mechanism or mount a cam, while adjustable air cushioning at both ends provides kinetic energy deceleration over 27mm. It operates at speeds from 30 to 800mm/s using a PT1/8 port.
Airtac SED Double Rod Cylinder SED32X85 Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø32 mm |
| Stroke | 85 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 SED32X85 Is Used
PCB Edge Guiding
Provides 345N of equal both-way force to tension and guide electronic circuit boards during conveyor transport without rotational deflection.
Pick-and-Place Transfer
Uses the rear rod end to mount a secondary cam, synchronizing dual-side part handling with matching extend and retract speeds.
Small Component Pressing
Delivers precise 483N at 0.7MPa for inserting pins or dual-action light pressing tasks where symmetrical force is required.
Is the Airtac SED Double Rod Cylinder SED32X85 the Right Cylinder?
When sizing this 32mm bore, stepping down is not an option as it is the smallest available SED frame. If you need more thrust, the next bore up is the 40mm version, which provides 528N of both-way force at 0.5 MPa. Choose this double-rod SED over a single-rod SE when your application demands higher resistance to torsional side loads, requires driving a secondary mechanism from the rear rod, or needs identical push and pull speeds. Remember that a plain SED does not hold position on air loss; the piston drifts, and the adjustable cushion only decelerates near stroke end rather than locking. For fail-safe holding, consider a BSED double-rod rod lock or an external pilot-operated check valve. To replace an existing ISO 15552 cylinder, match the 32mm bore, 85mm stroke, PT1/8 port, and mounting style from the available Basic, FA, LB, TC, FTC, TCM1, or TCM2 sets.
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 SED32X85 FAQ
Because the double-rod design has equal piston areas on both sides, the force is identical in both directions: 345N at 0.5 MPa, 483N at 0.7 MPa, and a maximum of 70 kgf at 1.0 MPa.
Yes, the SED32X85 is dimensionally interchangeable per ISO 15552. Just ensure you match the 85mm stroke, PT1/8 port, and use the supported mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), noting that FB, CA, CB, and CR mounts are omitted from this series.
