Airtac SED Double Rod Cylinder SED80X115
The AirTAC Airtac SED Double Rod Cylinder SED80X115 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 115mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X115
The AirTAC SED80X115 is a double-acting, double-rod profile cylinder operating on the ISO 15552 interface. Because a 25mm rod exits both end covers, the annular piston area is symmetrical. This generates an equal 2268 N of drive force in both directions at 0.5 MPa, eliminating speed discrepancies between extend and retract strokes.
This extruded aluminum unit features field-adjustable air cushioning at both ends (36mm stroke) to manage kinetic energy. It carries no standard magnet, meaning position sensing is absent on this SKU. The rear protrusion is ideal for mounting a cam or driving a secondary mechanism, though you must design rear-rod clearance into your machine layout.
Airtac SED Double Rod Cylinder SED80X115 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED80X115 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 115 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 SED80X115 Is Used
Web Guiding Brakes
Provides 2268 N of equal force to clamp and steer film webs without skewing, using the twin rods to prevent brake pad rotation.
Dual-Side Pick & Place
Drives a transfer gantry where the rear rod end mounts a physical limit flag, maintaining precise 115mm strokes for component shuttling.
Multi-Spindle Drilling
Lowers a drill head with symmetrical retract force, using the double-rod rigidity to keep the spindle perpendicular during metal cutting.
Is the Airtac SED Double Rod Cylinder SED80X115 the Right Cylinder?
Select this 80mm bore when your application requires 2268 N of bidirectional force at 0.5 MPa. If your load is lighter, the 63mm bore provides 1402 N both ways. For heavier thrust up to 3681 N, step up to the 100mm bore. This twin-rod design prevents piston rotation better than a single-rod SE cylinder, offering dual-side guidance for rigid loads.
As a drop-in ISO 15552 replacement, match the 115mm stroke, PT3/8 port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that plain air pressure cannot hold position on failure; the piston drifts. For fail-safe holding, use an external rod lock or a BSED double-rod lock variant.
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 SED80X115 FAQ
Because the double-rod design has equal piston area on both sides, output force is identical 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.
It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts. It omits FB, CA, CB, and CR styles. You must also leave physical clearance for the rear rod protruding from the back cover.
