Airtac SED Double Rod Cylinder SED40X90
The AirTAC Airtac SED Double Rod Cylinder SED40X90 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 90mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED40X90
The AirTAC SED40X90 is a double-acting, double-rod profile cylinder conforming to ISO 15552. Because a 16 mm rod occupies both piston faces, the annulus area is symmetrical, yielding an equal 528 N of thrust in both directions at 0.5 MPa. The extruded aluminum barrel has no external tie rods, and adjustable air cushions at both ends absorb kinetic energy near the stroke limits.
This 40 mm bore unit features a PT1/4 port and M12x1.25 rod-end threads. Without the -S magnet option, this SKU omits internal position sensing, but the extending rear rod can mount an external cam or flag to trigger external switches while driving a secondary mechanism.
Airtac SED Double Rod Cylinder SED40X90 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED40X90 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 90 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 SED40X90 Is Used
PCB Edge Deburring Station
Uses the 528 N equal both-way force to clamp and brush circuit board edges uniformly in both pass directions without speed or torque variance.
Pick-and-Place Gantry
The twin 16 mm rods prevent gripper rotation during fast horizontal transfers, ensuring precise component placement on the production line.
Reciprocating Diverting Flap
Drives a sorting gate from both ends, utilizing the rear rod to mount a physical cam flag that trips external limit switches.
Is the Airtac SED Double Rod Cylinder SED40X90 the Right Cylinder?
Choose this 40 mm bore when an application requires exactly 528 N of bidirectional force at 0.5 MPa. If your load demands less thrust, step down to the 32 mm bore providing 345 N both ways; for heavier drives, step up to the 50 mm bore delivering 825 N. The twin-rod design inherently resists torsional load and prevents rod rotation, making it superior to a single-rod SE cylinder for guiding heavy vertical slides.
Remember that a standard SED does not hold position on air loss—the piston drifts, and the adjustable cushion only decelerates near stroke end, acting as a brake. For fail-safe holding, consider a BSED rod-lock variant. As a true ISO 15552 cylinder, you can drop-in replace any matching ISO 15552 double-rod unit by matching the 90 mm stroke, PT1/4 port, and your preferred mounting from 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 SED40X90 FAQ
Because the double-rod design creates equal piston areas on both sides, the output force is identical in extend and retract. It provides 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa.
Yes. The SED40X90 is a true ISO 15552 profile cylinder, meaning it is dimensionally interchangeable with any standard ISO 15552 double-rod cylinder. Just verify your 90 mm stroke, PT1/4 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2) match the footprint.
