Airtac SED Double Rod Cylinder SED40X95S
The AirTAC Airtac SED Double Rod Cylinder SED40X95S 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 95mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED40X95S
The AirTAC SED40X95S is a double-acting, double-rod profile cylinder built to the ISO 15552 interface. A 16mm rod extends from both end covers, yielding identical annulus areas and equal force in both directions—delivering 528N at 0.5 MPa and 739N at 0.7 MPa on extend and retract.
Equipped with a standard magnet (-S), it supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. The extruded aluminum barrel omits external tie rods, and adjustable air cushions at both ends protect your machinery over the 95mm travel.
Airtac SED Double Rod Cylinder SED40X95S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED40X95S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 95 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 SED40X95S Is Used
PCB Depaneling Saw
Drives a circular blade on the front rod while the rear rod operates a tension flag, utilizing the 528N equal both-way force to cut and clear boards smoothly.
Bottle Reject Arm
Mounts a paddle on one end and a counterweight on the other; the twin-rod anti-rotation design keeps the reject stroke stable at high speeds.
Dual-Side Transfer Gate
Uses both rod ends to push and pull a transfer gate simultaneously, ensuring perfectly balanced motion without differential speed lag.
Is the Airtac SED Double Rod Cylinder SED40X95S the Right Cylinder?
This 40mm bore provides 528N both ways at 0.5 MPa. If your application requires less force, the 32mm bore yields 345N; if you need more, the 50mm bore provides 825N. Choose this double-rod SED over a single-rod SE when you need to mount a cam or secondary actuator on the rear shaft, or when twin-side guidance is required to prevent load rotation.
For a drop-in ISO 15552 replacement, match the 95mm stroke, PT1/4 port, and preferred mounting (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that a plain SED does not hold position on air loss; for fail-safe holding, use a BSED double-rod rod lock or an external pilot-operated check valve.
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 SED40X95S FAQ
Because the double-rod design creates equal annulus areas on both sides, the force is identical in both directions: 528N at 0.5 MPa, 739N at 0.7 MPa, and a maximum of 108kgf at 1.0 MPa.
Yes. The SED40X95S is dimensionally interchangeable per ISO 15552. Just verify your 95mm stroke, PT1/4 port, M12x1.25 rod thread, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2) match your existing fixture.
