Airtac SED Double Rod Cylinder SED32X475S
The AirTAC Airtac SED Double Rod Cylinder SED32X475S is a genuine double-acting ISO 15552 double-rod cylinder: a Ø12mm piston rod exits BOTH ends of the Ø32mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 475mm, PT1/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED32X475S
The AirTAC SED32X475S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a rod exits both ends, the effective piston area is identical in both directions, yielding an equal force of 345 N each way at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, and the -S suffix means a magnet is pre-installed for CMSE reed or DMSE electronic sensors.
Field-adjustable air cushions at both ends manage deceleration over the 27 mm cushion length. The twin 12 mm rods (M10x1.25 thread) improve load guidance against rotation, while the rear rod can simultaneously drive a secondary mechanism or carry a sensor flag. Note that overall length is longer than a single-rod SE, requiring rear clearance.

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø32 mm |
| Stroke | 475 mm |
| Configuration | Double rod, double acting |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| 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, 27 mm |
| Max stroke | Up to 1000 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 (Ø32mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 346 N |
| 0.7 MPa | 484 N |
| Max (@1.0 MPa) | 70 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 SED32X475S Is Used
PCB Routing Spindle
Drives a light-duty routing spindle on one end and a cam on the rear, using the 345 N equal both-way force to maintain consistent cutting pressure.
Package Flap Diverter
Alternates diverter flaps on a packaging line, relying on the 475 mm stroke and twin 12 mm rods to prevent binding during high-speed 30-800 mm/s actuation.
Lab Sample Ejector
Pushes analytical samples out of a test chamber using both rod ends, with the rear rod carrying a DMSE electronic sensor flag for precise position confirmation.
Is the Airtac SED Double Rod Cylinder SED32X475S the Right Cylinder?
At 475 mm stroke, the 32 mm bore provides 345 N both ways at 0.5 MPa. If your mechanism needs less force, there is no smaller SED bore, so you must reduce pressure or use a compact cylinder. If you need more push-pull, step up to the 40 mm bore, which delivers 528 N both ways at 0.5 MPa. Because this stroke exceeds 300 mm, external side-load guides are strongly recommended to prevent rod binding.
Choose this double-rod SED over a single-rod SE when you need anti-rotation stability, dual-end tooling, or rear-mounted sensing. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. Remember that air cushions only decelerate near stroke end; they do not hold position on air loss. For fail-safe holding, use a BSED double-rod lock cylinder 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 SED32X475S FAQ
The SED32X475S provides equal force in both extend and retract directions due to the double-rod design. It delivers 345 N at 0.5 MPa, 483 N at 0.7 MPa, and a maximum of 70 kgf at 1.0 MPa.
The twin rods offer better anti-rotation guidance and allow the rear rod to drive a secondary mechanism or sensor flag. It is dimensionally interchangeable per ISO 15552, uses a PT1/8 port, and provides identical push and pull forces.
