Airtac SED Double Rod Cylinder SED40X80
The AirTAC Airtac SED Double Rod Cylinder SED40X80 is a genuine double-acting ISO 15552 double-rod cylinder: a Ø16mm piston rod exits BOTH ends of the Ø40mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 80mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED40X80
The AirTAC SED40X80 is a double-acting, double-rod profile cylinder built to ISO 15552 and VDMA 24562 dimensional standards. Because a 16 mm rod exits both end covers, the effective piston area is identical on extend and retract, yielding 528 N of force each way at 0.5 MPa. The extruded aluminum barrel lacks external tie rods, and field-adjustable air cushions at both ends decelerate the load near stroke end.
This 80 mm stroke unit uses PT1/4 ports and an M12x1.25 rod-end thread. Without the -S suffix, this specific SKU omits the internal magnet, meaning it cannot host CMSE reed or DMSE electronic sensors directly on the body. The rear rod extension is fully exposed, providing an ideal mounting point for external cam flags or secondary tooling that requires anti-rotation guidance.
Airtac SED Double Rod Cylinder SED40X80 Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 80 mm |
| Configuration | Double rod, double acting |
| Port size | PT1/4 |
| Rod thread | M12×1.25 |
| 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, 30 mm |
| Max stroke | Up to 1200 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 (Ø40mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 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 SED40X80 Is Used
PCB Edge-Trimming Fixture
Drives a cutting blade with 528 N both ways at 0.5 MPa, using the twin rods to prevent blade yaw during precision circuit board trimming.
Bottle Diverting Gate
Actuates a dual-sided diverter arm on a packaging line, pushing with equal 739 N force at 0.7 MPa in both directions for rapid lane changes.
Small Part Ejection
Ejects stamped metal parts from a press die, using the rear rod end to trigger an external mechanical flag signaling the ejection cycle.
Is the Airtac SED Double Rod Cylinder SED40X80 the Right Cylinder?
Choose this 40 mm bore when you need 528 N of thrust and retraction at 0.5 MPa. If your application requires less force, step down to the 32 mm bore, which provides 345 N both ways. If you need more power, the 50 mm bore offers 825 N both ways at 0.5 MPa. The twin-rod design is preferred over a single-rod SE cylinder when driving a load that must not rotate, or when a secondary mechanism must be actuated from the rear rod.
Remember that the adjustable air cushion only decelerates the piston near the end of travel; it does not hold position on air loss. For fail-safe holding, consider a BSED double-rod rod lock or an external pilot-operated check valve. When replacing an existing ISO 15552 cylinder, verify the 80 mm stroke, PT1/4 port, and mounting style (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 SED40X80 FAQ
The double-rod design provides equal force in both directions: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa.
This specific SKU lacks the internal magnet (-S suffix), so it cannot host CMSE or DMSE sensors. However, the rear protruding rod is ideal for mounting an external cam or physical limit flag to trigger external sensors.
