Airtac SED Double Rod Cylinder SED80X170
The AirTAC Airtac SED Double Rod Cylinder SED80X170 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 170mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X170
The AirTAC SED80X170 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80mm bore and 170mm stroke. Because a 25mm rod exits both end covers, the effective piston area is identical on extend and retract. This yields equal force of 2268 N at 0.5 MPa in both directions.
This unit lacks the -S magnet option, meaning no CMSE or DMSE position sensors can be mounted on this SKU. The extruded aluminum barrel omits external tie rods, and field-adjustable air cushions at both ends decelerate the load near stroke end without acting as a lock.
Airtac SED Double Rod Cylinder SED80X170 Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 170 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 |

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 SED80X170 Is Used
CNC Pallet Changer
Drives an indexing pallet shuttle with 2268 N of equal both-way force, using the rear rod to mount a physical cam that triggers the machine door interlock.
Package Flipping Station
Inverts heavy cardboard cartons on a packaging line, leveraging the twin rods to prevent torsional twist and maintain parallel platen alignment.
Web Edge Guiding
Positions a heavy paper web guide roller in a converting mill, relying on the double-rod geometry for precise anti-rotation tracking during 170mm shifts.
Is the Airtac SED Double Rod Cylinder SED80X170 the Right Cylinder?
Selecting this 80mm bore provides 2268 N of both-way force at 0.5 MPa. Stepping down to the 63mm bore yields 1402 N, while stepping up to the 100mm bore provides 3681 N at the same pressure. Choose this double-rod SED over a single-rod SE when your application demands high resistance to side loads, anti-rotation stability, or the ability to mount a rear-rod cam. As a true ISO 15552 cylinder, it is a dimensionally interchangeable drop-in replacement matching the 80mm bore, 170mm stroke, PT3/8 port, and mounting footprint. Note that a plain SED does not hold position on air loss; for fail-safe holding, consider a BSED rod-lock cylinder or external check valve. At 170mm stroke, external guide rods are recommended to manage any side 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 SED80X170 FAQ
Because the 25mm rod occupies both sides of the piston, force is equal in both directions: 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 prevent piston rotation and allow the rear rod to drive a secondary mechanism or sensor flag. It uses an ISO 15552 mounting interface but omits FB, CA, CB, and CR mounts, offering Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.
