Airtac SED Double Rod Cylinder SED80X160
The AirTAC Airtac SED Double Rod Cylinder SED80X160 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 160mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X160
The AirTAC SED80X160 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80mm bore and 160mm stroke. A 25mm rod extends from both end covers, yielding identical annulus areas. This means you generate 2268 N of thrust in both directions at 0.5 MPa, completely eliminating the force differential found in single-rod units.
This unit lacks the -S magnet option, so it has no internal position sensing. It uses a default PT3/8 port and a field-adjustable air cushion at both ends to decelerate the load near stroke end. The rear rod extension can drive a secondary mechanism or mount a physical cam, while the twin-rod geometry actively resists torsional twist.

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 SED80X160 Is Used
CNC Lathe Bar Feeder
Pushes raw bar stock through a spindle. The twin rods prevent rotational binding under high friction, applying 2268 N at 0.5 MPa without twisting.
Pallet Transfer Reject Arm
Uses the rear rod to trigger a mechanical flag while the front rod diverts heavy pallets. Equal both-way force ensures smooth retraction without spring lag.
Textile Calender Nip Roller
Applies uniform nip pressure across fabric. The double-rod geometry maintains parallel roller alignment, utilizing 3175 N at 0.7 MPa for consistent material feed.
Is the Airtac SED Double Rod Cylinder SED80X160 the Right Cylinder?
At 0.5 MPa, this 80mm bore delivers 2268 N both ways. If your load is lighter, the 63mm bore provides 1402 N. If you need more power, the 100mm bore yields 3681 N. Choose this double-rod SED over a single-rod SE when a mechanism demands anti-rotation stability or requires mounting a physical flag to the rear rod. As a true ISO 15552 cylinder, it drops into standard dimensional interfaces using Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts (omitting FB, CA, CB, CR). Note that air cushions only decelerate; they do not lock. The piston drifts on air loss, so use a BSED double-rod lock for fail-safe holding. At 160mm stroke, keep side loads minimized via external guide rails.
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 SED80X160 FAQ
Because a rod exits both ends, the effective area 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.
The twin 25mm rods provide superior torsional rigidity and prevent rotation, making it ideal for guiding heavy loads. The rear rod can also drive a secondary mechanism, and it is dimensionally interchangeable per ISO 15552.
