Airtac SED Double Rod Cylinder SED40X475
The AirTAC Airtac SED Double Rod Cylinder SED40X475 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 475mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED40X475
The AirTAC SED40X475 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40 mm bore and 475 mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding a perfectly symmetrical 528 N of force at 0.5 MPa in both directions. The extruded aluminum barrel contains no external tie rods, ensuring a clean profile that drops into standard ISO 15552 mounting interfaces.
This unit lacks the -S magnet option, meaning it has no integrated position sensing on this SKU. It utilizes a PT1/4 port, a 16 mm rod with an M12x1.25 thread, and field-adjustable air cushions at both ends to manage deceleration over the long travel distance.

| 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 |

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 SED40X475 Is Used
Transfer Line Diversion
Drives a dual-sided diverter arm on a packaging conveyor, utilizing the 528 N both-way force to push products evenly without rotational drift.
Multi-Station Processing
Powers a rear-rod cam on an automated CNC lathe loader, actuating a secondary gripper while the front rod advances the workpiece.
Equal-Tension Clamping
Synchronizes a two-sided clamping fixture in a woodworking machine, ensuring the 16 mm rods apply identical 739 N clamping pressure at 0.7 MPa.
Is the Airtac SED Double Rod Cylinder SED40X475 the Right Cylinder?
At 0.5 MPa, this 40 mm bore generates 528 N of equal both-way force. If your payload is lighter, stepping down to the 32 mm bore drops the output to 345 N. For heavier loads, the 50 mm bore increases thrust to 825 N. Choose this double-rod SED over a single-rod SE when the mechanism requires anti-rotation stability or needs to drive a secondary tool from the rear rod end.
With a 475 mm stroke, the extended rod length amplifies side-load leverage; you must use external linear guides to prevent binding. Note that the adjustable air cushion only decelerates the piston near stroke end—it does not hold position on air loss. For fail-safe holding, consider an external pilot-operated check valve or a BSED rod-lock cylinder. To replace an ISO 15552 unit, match the 40 mm bore, 475 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 SED40X475 FAQ
Because the double-rod design subtracts the rod area from both sides, force is equal 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.
The twin rods provide superior anti-rotation guidance and allow the rear rod end to drive a secondary mechanism or limit flag. It is dimensionally interchangeable per ISO 15552, but omits the FB, CA, CB, and CR mounting styles.
