Airtac SED Double Rod Cylinder SED80X70S
The AirTAC Airtac SED Double Rod Cylinder SED80X70S 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 70mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X70S
The AirTAC SED80X70S is a double-acting, double-rod ISO 15552 profile cylinder. A 25mm rod extends from both end covers, yielding identical annulus areas. This means output force is perfectly balanced, delivering 2268N each way at 0.5MPa. The extruded aluminum barrel contains no external tie rods, ensuring a clean profile.
Fitted from the factory with a magnet (-S), it 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. The rear rod extension is perfect for mounting a cam or secondary mechanism.
Airtac SED Double Rod Cylinder SED80X70S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED80X70S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 70 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 |
| Max stroke | Up to 1500 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 SED80X70S Is Used
Servo Press Sub-bases
Provides 3175N of equal push and pull force at 0.7MPa for stamping sub-bases, using the twin rods to resist deflection under offset loads.
Pallet Transfer Rejects
Drives a dual-sided reject arm on a conveyor line. The rear rod simultaneously triggers a DMSE electronic sensor to confirm the reject stroke.
Web Guide Rollers
Equal both-way force prevents directional drift when tensioning web materials, while the double-rod geometry maintains precise parallel tracking.
Is the Airtac SED Double Rod Cylinder SED80X70S the Right Cylinder?
Choose this 80mm bore when your application needs 2268N (0.5MPa) or 3175N (0.7MPa) of equal bidirectional force. If your load is lighter, the 63mm bore provides 1402N at 0.5MPa. For heavier drives, stepping up to the 100mm bore yields 3681N at 0.5MPa. The twin-rod design provides superior anti-rotation guidance compared to a single-rod SE cylinder.
A plain SED does not hold position on air loss; the piston drifts. For fail-safe holding, use a BSED double-rod rod lock. To replace an ISO 15552 unit, match the 80mm bore, 70mm stroke, PT3/8 port, and mounting interface (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
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 SED80X70S FAQ
Because the rod occupies both sides of the piston, force is equal in both directions. It provides 2268N at 0.5MPa, 3175N at 0.7MPa, and a maximum of 463kgf at 1.0MPa.
The twin rods prevent piston rotation and allow you to mount tooling, cams, or sensors on the rear rod end. It also provides perfectly balanced force for push and pull operations.
