Airtac SED Double Rod Cylinder SED32X80LB
The AirTAC Airtac SED Double Rod Cylinder SED32X80LB 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 80mm, PT1/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED32X80LB
The AirTAC SED32X80LB 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 yields exactly 345 N of thrust each way at 0.5 MPa, eliminating directional force mismatch.
This 32mm bore unit features a 27mm adjustable air cushion at both ends to manage end-of-stroke deceleration. Equipped with an LB foot mounting bracket, it provides a stable base. Note that this specific SKU lacks a magnet, so it cannot host CMSE or DMSE position sensors without modification.
Airtac SED Double Rod Cylinder SED32X80LB Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED32X80LB |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø32 mm |
| Stroke | 80 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 SED32X80LB Is Used
Slitting Line Guide
Provides 345 N of equal bidirectional force to precisely position cutting blades on a slitting line, ensuring the rear rod prevents blade rotation during retraction.
Transfer Pusher
Drives a dual-sided transfer pusher on a packaging conveyor, using the twin 12mm rods to keep the pusher plate perfectly aligned without twisting under load.
Cam Actuator
Uses the protruding rear rod to actuate a mechanical limit cam on an automated test fixture, saving space by combining drive and signaling in one cylinder.
Is the Airtac SED Double Rod Cylinder SED32X80LB the Right Cylinder?
Stepping down is not an option as 32mm is the smallest available SED bore. If your application demands more force, the next size up is the 40mm bore, which provides 528 N both ways at 0.5 MPa. Choose this twin-rod design over a single-rod SE when you need to mount a cam or secondary tool on the rear extension, or when the load requires strict anti-rotation guidance. Remember that an SED relies on air pressure to maintain position; it will drift on air loss. For fail-safe holding, consider a BSED rod-lock variant or an external pilot-operated check valve.
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 SED32X80LB FAQ
The SED32X80LB provides equal force in both directions due to its twin rods: 345 N at 0.5 MPa, 483 N at 0.7 MPa, and a maximum of 70 kgf at 1.0 MPa.
Yes, the SED32X80LB is dimensionally interchangeable per ISO 15552 standards. Just match the 32mm bore, 80mm stroke, PT1/8 port, and LB foot mount.
