Airtac SED Double Rod Cylinder SED80X175
The AirTAC Airtac SED Double Rod Cylinder SED80X175 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 SED80X175
The AirTAC SED80X175 is a double-acting, double-rod profile cylinder built to the ISO 15552 / VDMA 24562 dimensional interface. Because a Ø25 mm rod exits both end covers, the effective piston area is identical in both directions. This yields exactly 2268 N of force at 0.5 MPa on extend and retract alike.
The extruded aluminum barrel omits external tie rods for a clean profile. It features field-adjustable air cushions at both ends (36 mm cushion length) and a PT3/8 port. This specific SKU lacks a magnet, so it does not support CMSE or DMSE position sensing.

| 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 |

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 SED80X175 Is Used
CNC Lathe Bar Feeder
Uses the 2268 N both-way force to push and retract stock through the spindle, relying on the twin rods to prevent feeder tube rotation.
Transfer Line Shuttle
Indexes heavy pallets between machining stations, leveraging the equal extend and retract speeds for a balanced 175 mm transfer cycle.
Web Guide Mechanism
Drives a steering roller with the rear rod end while the front rod actuates the tensioner, keeping web tracking precise without torsional deflection.
Is the Airtac SED Double Rod Cylinder SED80X175 the Right Cylinder?
Stepping down to the 63 mm bore drops the both-way force to 1402 N at 0.5 MPa, while stepping up to the 100 mm bore increases it to 3681 N. Choose this 80 mm model when your mechanism needs the 2268 N output to drive twin loads or balance a heavy carriage. The twin rods provide superior anti-rotation guidance compared to a single-rod SE cylinder.
As a double-acting cylinder, it will drift if air pressure drops. The adjustable cushions only decelerate the piston near the stroke ends; they do not hold position. For fail-safe locking, consider an external rod lock or the BSED series. To replace an ISO 15552 unit, match the 80 mm bore, 175 mm stroke, PT3/8 port, and mounting choice (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 SED80X175 FAQ
Because the double-rod design has equal piston area on both sides, it generates 2268 N at 0.5 MPa and 3175 N at 0.7 MPa in both directions. The maximum force is 463 kgf at 1.0 MPa.
Yes. The SED80X175 is a profile cylinder dimensionally interchangeable per ISO 15552. You can drop it in by matching the 80 mm bore, 175 mm stroke, PT3/8 port, and your mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
