Airtac SED Double Rod Cylinder SED80X15S
The AirTAC Airtac SED Double Rod Cylinder SED80X15S 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 15mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X15S
The AirTAC SED80X15S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding exactly 2268 N of force in both directions at 0.5 MPa. This eliminates speed and force mismatch between strokes.
Fitted with the -S magnet option, this 80mm bore unit supports DMSE electronic and CMSE reed sensors for end-of-stroke detection. The short 15mm stroke is perfect for compact clamping or gating, while the rear rod end provides a secondary mounting point for cams or linkage drives.

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 SED80X15S Is Used
Servo Press Peening
Drives a short-stroke peening head with 2268 N of equal force both ways, using the rear rod to trigger a mechanical cam.
Glass Panel Transfer
Actuates a dual-side gripper on a CNC loader; the twin rods prevent jaw twisting during high-speed 15mm clamping.
PCB Stencil Wiping
Indexes a wiper blade across a stencil. The double-rod geometry ensures the blade maintains uniform pressure in both directions.
Is the Airtac SED Double Rod Cylinder SED80X15S the Right Cylinder?
Select this 80mm bore if your application requires high bidirectional force in a very short footprint. If you need less force, the adjacent 63mm bore provides 1402 N at 0.5 MPa; stepping up is not possible as 80mm is the second largest standard size, but the 100mm bore offers 3681 N if you need more. The twin-rod design inherently resists torsional rotation better than a single-rod SE cylinder, guiding the load on two parallel axes.
This model includes the -S magnet for position sensing and uses a PT3/8 port. Remember that a standard SED does not hold position upon air loss; the piston will drift. For fail-safe holding, consider a BSED double-rod rod lock or an external pilot-operated check valve. The adjustable air cushions at both ends decelerate the load near stroke end but do not function as a brake.
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 SED80X15S FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It provides 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and a maximum of 463 kgf at 1.0 MPa.
Yes, the SED80X15S is dimensionally interchangeable per ISO 15552 / VDMA 24562 profile standards. Just match the bore, stroke, PT3/8 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
