Airtac SED Double Rod Cylinder SED40X375
The AirTAC Airtac SED Double Rod Cylinder SED40X375 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 375mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED40X375
The AirTAC SED40X375 is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a 16mm rod exits both ends of the 40mm piston, the effective area is identical on extend and retract, yielding an equal 528N of thrust each way at 0.5MPa. The extruded aluminum barrel contains no external tie rods, maintaining a clean profile.
This 375mm stroke unit lacks a standard magnet (-S), meaning it cannot host CMSE or DMSE sensors directly on the body. Field-adjustable air cushions at 30mm length grace both ends to smooth out end-of-stroke impacts, but they only decelerate the load; they do not lock it in place.
Airtac SED Double Rod Cylinder SED40X375 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED40X375 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 375 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 SED40X375 Is Used
Printed Circuit Board Scoring
Drives a V-score blade across PCB panels with 528N of equal both-way force, using the rear rod to push the blade back without a secondary actuator.
Pouch Transfer Pusher
Alternately pushes filled pouches to two packaging lanes using both rod ends, preventing rod binding during fast 30-800mm/s cycling.
Wire Stripping Clamp
Grips wire bundles securely for automated stripping, relying on the twin rods to keep the clamping jaw perfectly parallel and rotation-free.
Is the Airtac SED Double Rod Cylinder SED40X375 the Right Cylinder?
Choose this 40mm bore if your mechanism needs exactly 528N both ways at 0.5MPa. If your load is lighter, step down to the 32mm bore for 345N; if heavier, step up to the 50mm bore for 825N. The twin-rod design is preferred over a single-rod SE when you need to mount a rear-rod cam, drive two mechanisms in opposition, or guide a load against yaw and rotation. At 375mm of stroke, the 16mm rod needs external support guides to prevent sagging and side-load wear. For drop-in replacements, match the 375mm stroke, PT1/4 port, and your mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that a plain SED drifts on air loss; use a BSED double-rod lock for fail-safe holding.
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 SED40X375 FAQ
Because the double-rod design subtracts rod area from both sides, thrust is identical in both directions: 528N at 0.5MPa, 739N at 0.7MPa, and a maximum of 108kgf at 1.0MPa.
Yes, the SED40X375 is dimensionally interchangeable per ISO 15552. Just match your mounting style (Basic, FA, LB, TC, FTC, TCM1, TCM2) and ensure you have rear-rod clearance, as a rod protrudes from both end covers.
