Airtac SED Double Rod Cylinder SED80X170S
The AirTAC Airtac SED Double Rod Cylinder SED80X170S 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 SED80X170S
The AirTAC SED80X170S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 170 mm stroke. A Ø25 mm rod extends from both end covers, providing identical annulus areas. This yields equal extend and retract forces of 2268 N at 0.5 MPa, ensuring perfectly balanced bidirectional motion.
Equipped with a standard -S magnet, it interfaces directly with CMSE reed and DMSE electronic sensors in the extruded barrel grooves. The field-adjustable air cushions at both ends decelerate the load near stroke end, while the PT3/8 ports supply the 30-800 mm/s speed range.
Airtac SED Double Rod Cylinder SED80X170S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED80X170S |
|---|---|
| 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 |
| 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 SED80X170S Is Used
Web Guiding Mechanism
Provides 2268 N of equal bidirectional force to steer heavy material webs, using the twin rods to prevent binding and resist rotational torque.
Pallet Transfer Stop
Uses the protruding rear rod to trigger an external DMSE sensor flag, confirming the 3175 N stopping position without external brackets.
Dual-Side Press
Drives opposing clamps simultaneously, leveraging the 36 mm adjustable cushions to absorb impact at both 170 mm stroke endpoints.
Is the Airtac SED Double Rod Cylinder SED80X170S the Right Cylinder?
At 0.5 MPa, this 80 mm bore generates 2268 N both ways. If your drive needs less force, the 63 mm bore provides 1402 N; for heavier loads, step up to the 100 mm bore offering 3681 N. Choose this double-rod unit over a single-rod SE when your application demands high anti-rotation resistance or requires mounting a rear-rod cam for secondary actuation. Remember to leave rear-rod clearance, as the overall length exceeds a single-rod cylinder. For fail-safe position holding on air loss, use a BSED rod lock, as the cushions only decelerate.
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 SED80X170S FAQ
The SED80X170S delivers equal force in both directions due to its double-rod design. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and reaches a maximum of 463 kgf at 1.0 MPa.
The twin rods offer superior anti-rotation guidance and allow the rear rod to drive a secondary mechanism or sensor flag. It is dimensionally interchangeable per ISO 15552, but omits FB, CA, CB, and CR mounts, supporting only Basic, FA, LB, TC, FTC, TCM1, and TCM2.
