Airtac SED Double Rod Cylinder SED80X5S
The AirTAC Airtac SED Double Rod Cylinder SED80X5S is a genuine double-acting ISO 15552 double-rod cylinder: a Ø25mm piston rod exits BOTH ends of the Ø80mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 5mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X5S
The AirTAC SED80X5S is a double-acting, double-rod ISO 15552 profile cylinder engineered for exceptionally short 5mm strokes. Because a 25mm rod exits both end covers, the effective piston area is identical on extend and retract. This yields equal force and speed in both directions, delivering 2268 N at 0.5 MPa.
Equipped with a standard magnet (-S), it supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. The extruded aluminum barrel contains no external tie rods, and field-adjustable air cushions at both ends manage deceleration. The rear rod extension is perfect for mounting a cam or driving a secondary mechanism in compact spaces.
Airtac SED Double Rod Cylinder SED80X5S Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 5 mm |
| Configuration | Double rod, double acting |
| Port size | PT3/8 |
| Rod thread | M20×1.5 |
| 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, 36 mm |
| Max stroke | Up to 1500 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 (Ø80mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 2268 N |
| 0.7 MPa | 3175 N |
| Max (@1.0 MPa) | 463 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 SED80X5S Is Used
Precision Gripper Actuation
Provides 2268 N of equal both-way force to open and close heavy-duty robotic grippers, using the short 5mm stroke for rapid part clamping.
Dual-Side Sealing Press
Uses the twin rods exiting both ends to apply balanced sealing pressure from two sides simultaneously, preventing workpiece deformation.
Short-Stroke Forming Die
Drives a compact forming die where the rear rod simultaneously triggers a mechanical limit flag for precise process timing.
Is the Airtac SED Double Rod Cylinder SED80X5S the Right Cylinder?
Select this 80mm bore when an application demands 2268 N of both-way force within a tiny 5mm stroke. If you need less power, the 63mm bore provides 1402 N at 0.5 MPa. If you require more thrust, the 100mm bore offers 3681 N. The twin-rod design provides superior anti-rotation stability compared to a single-rod SE cylinder.
For ISO 15552 dimensional replacements, match the 80mm bore, 5mm stroke, PT3/8 port, and magnet option. Note that a plain SED does not hold position on air loss; the piston drifts. The adjustable cushion decelerates near stroke end but is not a lock. For fail-safe holding, use a BSED double-rod rod lock.
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 SED80X5S FAQ
The SED80X5S provides equal force in both directions because of the double-rod design. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and a maximum of 463 kgf at 1.0 MPa.
The double-rod design ensures identical extend and retract speeds while offering superior anti-rotation guidance. The protruding rear rod can also drive a secondary mechanism or mount a sensor cam.
