Airtac SED Double Rod Cylinder SED50X475
The AirTAC SED Double Rod Cylinder SED50X475 is a genuine double-acting ISO 15552 double-rod cylinder: a Ø20mm piston rod exits BOTH ends of the Ø50mm 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 SED50X475
The AirTAC SED50X475 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 475mm stroke. Because a 20mm rod exits both ends, the effective piston area is identical in each direction, yielding equal force of 825N at 0.5MPa on extend and retract. The extruded aluminum barrel includes sensor grooves, though this specific SKU lacks the -S magnet option for CMSE or DMSE sensors.
This through-rod design provides superior anti-rotation guidance for external loads and allows a rear-rod cam or tooling mount to operate a secondary mechanism. Field-adjustable air cushions at both ends provide deceleration over 30mm, protecting your equipment at stroke endpoints.
Airtac SED Double Rod Cylinder SED50X475 Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 475 mm |
| Configuration | Double rod, double acting |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| 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 (Ø50mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 825 N |
| 0.7 MPa | 1155 N |
| Max (@1.0 MPa) | 168 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 SED50X475 Is Used
Web Guide Mechanism
Drives a film edge guide with 825N both ways, using the twin rods to prevent chassis yaw during rapid reversals.
Dual-Side Transfer Gate
Shifts a transfer carriage between stations, leveraging the rear rod to trigger a physical limit flag.
Is the Airtac SED Double Rod Cylinder SED50X475 the Right Cylinder?
This 50mm bore generates 825N both ways at 0.5MPa. If your application requires less force, step down to the 40mm bore (528N both ways); if you need more power, step up to the 63mm bore (1402N both ways). The twin rods are ideal over the 475mm stroke because they resist twisting better than a single-rod SE cylinder. At 475mm, external side loads should be guided externally to prevent rod binding. Remember that a plain SED does not hold position on air loss; for fail-safe holding, use a BSED double-rod lock. Replacement requires matching the 50mm bore, 475mm 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 SED50X475 FAQ
The SED50X475 provides equal force in both directions because of the double-rod design. It outputs 825N at 0.5MPa, 1154N at 0.7MPa, and a maximum of 168kgf at 1.0MPa.
The twin rods offer better load guidance and prevent rotation. The rear rod can also mount tooling or a sensor flag. It is dimensionally interchangeable per ISO 15552 but omits FB, CA, CB, and CR mounts.
