Airtac SED Double Rod Cylinder SED80X135S
The AirTAC Airtac SED Double Rod Cylinder SED80X135S 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 135mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X135S
The AirTAC SED80X135S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a 25mm rod exits both ends, the effective piston area is identical in extend and retract, yielding 2268 N of force each way at 0.5 MPa. The extruded aluminum barrel omits external tie rods for a clean profile.
Fitted with the -S magnet option, this unit supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. Field-adjustable air cushions at both ends decelerate the load near stroke end, while the rear rod can drive a secondary mechanism or carry a cam flag.

| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 135 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 |

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 SED80X135S Is Used
Web Guiding Mechanism
Drives a twin-rod equal-force equalizer for film or paper web tracking, using the 2268 N bidirectional output to tension and steer material without rotational deflection.
Dual-Side Machining Jig
Clamps a metal workpiece from both ends simultaneously, leveraging the 3175 N force at 0.7 MPa and the M20x1.5 rear rod to mount a secondary limit flag.
Transfer Pusher Assembly
Indexing heavy pallets along a production line where the 135mm stroke and twin-rod anti-rotation properties keep the pusher plate perfectly aligned under high side-loading.
Is the Airtac SED Double Rod Cylinder SED80X135S the Right Cylinder?
When sizing this 80mm bore, stepping down to the 63mm bore yields 1402 N both ways at 0.5 MPa, while stepping up to the 100mm bore provides 3681 N each way. Choose this SED over a single-rod SE when your application demands equal push/pull force, superior anti-rotation guidance via twin rods, or rear-rod tooling integration. As a drop-in ISO 15552 replacement, match your 80mm bore, 135mm stroke, PT3/8 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
Note that a plain SED does not hold position on air loss; the piston drifts. The air cushions only decelerate near stroke end and are not a lock. For fail-safe holding, consider a BSED double-rod lock cylinder 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 SED80X135S FAQ
Because the double-rod design yields equal effective area both ways, force is 2268 N at 0.5 MPa and 3175 N at 0.7 MPa in both extend and retract directions. The maximum force is 463 kgf at 1.0 MPa.
Yes, the SED80X135S is dimensionally interchangeable per ISO 15552 standards. Ensure you match the 80mm bore, 135mm stroke, PT3/8 port, and mounting interface (Basic, FA, LB, TC, FTC, TCM1, or TCM2), and leave rear-rod clearance.
