Airtac SED Double Rod Cylinder SED100X475S
The AirTAC Airtac SED Double Rod Cylinder SED100X475S is a genuine double-acting ISO 15552 double-rod cylinder: a Ø25mm piston rod exits BOTH ends of the Ø100mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 475mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X475S
The AirTAC SED100X475S is a double-acting, double-rod ISO 15552 profile cylinder engineered for high-load symmetry. A Ø25mm rod exits both end covers, yielding an identical annulus area on extend and retract. This design outputs exactly 3681 N each way at 0.5 MPa, preventing the force imbalance typical of single-rod units.
Equipped with a -S magnet, it interfaces directly with CMSE reed and DMSE electronic sensors. The extruded aluminum barrel lacks external tie rods, and field-adjustable air cushions at both ends decelerate the 475mm stroke. The protruding rear rod can mount a secondary cam or sensor flag to mirror motion.
Airtac SED Double Rod Cylinder SED100X475S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X475S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 475 mm |
| Configuration | Double rod, double acting |
| Port size | PT1/2 |
| Rod thread | M20×1.5 |
| 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, 36 mm |
| Max stroke | Up to 1500 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 (Ø100mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 3682 N |
| 0.7 MPa | 5154 N |
| Max (@1.0 MPa) | 751 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 SED100X475S Is Used
Servo Press Dismantler
Provides 5153 N of equal bidirectional force to extract and seat heavy motor end-caps, using the rear rod to drive a secondary parts ejector.
Pallet Strapping Ram
Tension and seal large packaging straps with 751 kgf of push and pull, ensuring consistent joint crimping while resisting frame rotation.
Textile Calender Guide
Drives a heavy fabric nip roller from both ends to maintain perfectly parallel tracking across a 475mm stroke without skewing.
Is the Airtac SED Double Rod Cylinder SED100X475S the Right Cylinder?
At 475mm, this 100mm bore generates 3681 N both ways at 0.5 MPa (751 kgf max at 1.0 MPa). If your payload is lighter, the 80mm bore provides 2268 N both ways. For heavier dynamics, the 125mm bore offers 5734 N. Because a rod extends from the rear cover, you must leave clearance for the 475mm protrusion.
For strokes over 300mm, external load guides are strongly recommended to prevent side-load friction on the long 475mm traverse. This SED does not hold position on air loss; for fail-safe locking, consider the BSED double-rod rod lock. To replace an ISO 15552 unit, match the 100mm bore, 475mm stroke, PT1/2 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 SED100X475S FAQ
Because the double-rod design creates equal piston areas, it outputs 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa in both extend and retract directions.
The twin rods provide superior anti-rotation guidance and allow the rear rod to drive a secondary mechanism or sensor flag. It also ensures identical speed and force both ways, dropping directly into standard ISO 15552 mounting interfaces.
