Airtac SED Double Rod Cylinder SED80X150S
The AirTAC Airtac SED Double Rod Cylinder SED80X150S 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 150mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X150S
The AirTAC SED80X150S is a double-acting, double-rod ISO 15552 profile cylinder with a 80mm bore and 150mm stroke. A piston rod exits both end covers, yielding identical annulus areas. Consequently, drive force is perfectly symmetrical, providing 2268 N in both directions at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, ensuring clean integration and true ISO 15552 dimensional interchangeability.
Equipped with a -S magnet, this unit directly supports CMSE reed and DMSE electronic sensors for dual-end position feedback. The rear rod extension is highly valuable for mounting a secondary mechanism, driving an external cam, or mounting a sensor flag. Field-adjustable air cushioning at both ends decelerates the load near stroke end, while the PT3/8 port handles the required pneumatic flow.

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 SED80X150S Is Used
Servo Press Sub-Assembly
Drives a secondary stamping head via the rear rod while the front rod executes the main press, utilizing the equal 2268 N both-way force to maintain balanced cycle dynamics.
Pallet Transfer Diverter
Rejects heavy pallets on a packaging line, using the twin-rod architecture to prevent load twisting during the 150mm extend and retract strokes.
Web Edge Guiding Frame
Tension and steer heavy industrial film webbing, relying on the dual-rod guidance to keep the 80mm bore mechanism perfectly aligned against lateral stress.
Is the Airtac SED Double Rod Cylinder SED80X150S the Right Cylinder?
Selecting this 80mm bore provides a robust 2268 N both-way force at 0.5 MPa. If your application requires less force, step down to the 63mm bore, which yields 1402 N both ways. For heavier loads, step up to the 100mm bore, providing 3681 N both ways. Choose this double-rod SED over a single-rod SE when the mechanism demands superior anti-rotation guidance, dual-side tooling, or rear-rod sensing capabilities. For a drop-in ISO 15552 replacement, match the 80mm bore, 150mm stroke, PT3/8 port, and -S magnet option.
Note that a plain SED does not hold position on air loss; the piston will drift. The adjustable air cushion only decelerates the load near stroke end and is not a lock or brake. For fail-safe holding, consider a BSED double-rod 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 SED80X150S FAQ
Because the double-rod design creates equal effective piston areas on both sides, the output force is identical in both directions. It delivers 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and a maximum of 463 kgf at 1.0 MPa.
A double-rod cylinder provides equal force and speed in both directions, which is critical for balanced machining. The rear rod allows mounting a secondary cam, tooling, or sensor flag, and the twin-rod guidance significantly improves resistance to rotational loads compared to a single-rod SE cylinder.
