Airtac SED Double Rod Cylinder SED80X80
The AirTAC Airtac SED Double Rod Cylinder SED80X80 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 80mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X80
The AirTAC SED80X80 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80mm bore and 80mm stroke. Because a 25mm rod exits both end covers, the effective piston area is identical on extend and retract, yielding an equal force of 2268 N at 0.5 MPa in both directions. The extruded aluminum barrel includes sensor grooves, though this specific SKU lacks the -S magnet option for position sensing.
This through-rod design excels at guiding loads against rotation and allows the rear rod end to drive a secondary mechanism or cam. It shares the SE barrel and adjustable air cushioning at both ends (36mm cushion length), but requires rear-rod clearance due to its longer overall length compared to a single-rod cylinder.

| 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 |

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 SED80X80 Is Used
Servo Press Anti-Rotation
Ideal for a multi-station servo press needing 2268 N both ways to form parts, using the twin rods to prevent wrenching under offset tooling loads.
Dual-Side Divert Gate
Drives a heavy conveyor diverting gate where the rear rod simultaneously pushes a secondary flag for timing, ensuring stable 3175 N actuation.
Mold Clamping Station
Clamps industrial molds on an assembly line, utilizing the equal extend and retract forces to securely seat and release heavy tooling without drift.
Is the Airtac SED Double Rod Cylinder SED80X80 the Right Cylinder?
Selecting this 80mm bore provides 2268 N of equal both-way force at 0.5 MPa. If your application requires less force, the adjacent 63mm bore offers 1402 N both ways; stepping up to the 100mm bore yields 3681 N both ways. Choose this double-rod SED over a single-rod SE when you need superior anti-rotation guidance, dual-side tooling, or a rear-mounted limit flag. As a true ISO 15552 profile cylinder, it drops into existing mounting interfaces using Basic, FA, LB, TC, FTC, TCM1, or TCM2 attachments (omitting FB/CA/CB/CR). To replace a cylinder, match the 80mm bore, 80mm stroke, PT3/8 port, and mounting style. Note that a plain SED does not hold position on air loss; for fail-safe holding, use a BSED rod-lock cylinder or external lock. The 25mm rod and M20x1.5 thread handle high side loads, but always verify external guide alignment.
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 SED80X80 FAQ
Because the 25mm rod occupies both sides of the piston, 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.
The twin-rod design provides superior anti-rotation guidance for heavy loads and allows the rear rod to drive a secondary cam or sensor flag. It is dimensionally interchangeable per ISO 15552, but requires rear-rod clearance and omits FB/CA/CB/CR mounts.
