Airtac SED Double Rod Cylinder SED80X175S
The AirTAC Airtac SED Double Rod Cylinder SED80X175S 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 175mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X175S
The AirTAC SED80X175S is a double-acting, double-rod ISO 15552 profile cylinder. A 25mm rod exits both end covers, yielding equal effective piston areas. This delivers 2268 N of thrust and pull each way at 0.5 MPa. The extruded aluminum barrel omits tie rods, and the -S option adds a magnet for DMSE electronic sensors.
Because the rear rod protrudes 175mm, you can mount a cam or secondary mechanism on the backside while the front drives the primary load. Field-adjustable air cushions at both ends decelerate the 30-800 mm/s motion. Remember that this cylinder drifts on air loss; it is not a lock.
Airtac SED Double Rod Cylinder SED80X175S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED80X175S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 175 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 SED80X175S Is Used
Pallet Diverters
Drives diverter arms on packaging lines using 3175 N of equal both-way force to push heavy pallets without rotational drift.
Multi-Spindle Drills
The rear 25mm rod supports a secondary cam plate, synchronizing drill heads while the front rod advances the spindle.
Textile Calendering
Applies uniform 2268 N clamping pressure on fabric rollers, using the twin-rod geometry to prevent uneven web tracking.
Is the Airtac SED Double Rod Cylinder SED80X175S the Right Cylinder?
Select this 80mm bore when you need 2268 N both ways at 0.5 MPa. If your load is lighter, the 63mm bore provides 1402 N both ways. If you need more power, stepping up to the 100mm bore yields 3681 N each way. The twin-rod design prevents torsion better than a single-rod SE, making it ideal for lifting heavy parallel guides.
For ISO 15552 replacements, match the 175mm stroke, PT3/8 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that FB, CA, CB, and CR mounts are omitted from this series. Since the stroke is under 300mm, side-load stress is moderate, but external guides are still recommended for heavy lateral loads.
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 SED80X175S FAQ
Because the 25mm rod occupies both sides of the piston, force is identical in both directions. It generates 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and a maximum of 463 kgf at 1.0 MPa.
The twin rods provide superior anti-rotation guidance and allow a rear-rod extension to mount a sensor flag or secondary mechanism. It also ensures the speed and force remain exactly equal on extend and retract.
