Airtac SED Double Rod Cylinder SED100X120S
The AirTAC Airtac SED Double Rod Cylinder SED100X120S 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 120mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X120S
The AirTAC SED100X120S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensions. A 25 mm rod extends from both end covers, yielding identical annulus areas. This means you get exactly 3681 N of output force in both directions at 0.5 MPa.
Equipped with a -S magnet, the unit supports DMSE electronic and CMSE reed sensors for end-of-stroke detection. The extruded aluminum barrel omits tie rods, and adjustable air cushions at both ends protect your machinery from impact near the 120 mm stroke limits.
Airtac SED Double Rod Cylinder SED100X120S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X120S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 120 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 SED100X120S Is Used
Servo Press Sub-Assembly
Drives a 3681 N bidirectional press head where the rear rod simultaneously triggers a DMSE sensor flag, ensuring perfectly synchronized up/down forming cycles.
Pallet Diverting Gate
Actuates a heavy diverter arm on a packaging line. The twin 25 mm rods prevent torsional twisting under off-center pallet loads, ensuring smooth 120 mm strokes.
Twin-Clutch Engagement
Shifts a dual-clutch gearbox mechanism where identical 5153 N engagement and disengagement force at 0.7 MPa is critical for balanced torque transfer.
Is the Airtac SED Double Rod Cylinder SED100X120S the Right Cylinder?
Choose this 100 mm bore when you need substantial equal bidirectional force. If 3681 N at 0.5 MPa is excessive, step down to the 80 mm bore providing 2268 N both ways. If you need more power, the 125 mm bore offers 5734 N. The twin-rod design inherently resists torsion, guiding loads against rotation better than a single-rod SE cylinder.
For drop-in replacements, match the 100 mm bore, 120 mm stroke, PT1/2 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that a plain SED does not hold position on air loss; the piston will drift. For fail-safe holding, specify a BSED double-rod rod lock 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 SED100X120S FAQ
Because the double-rod design creates equal piston areas on both sides, force is identical in both directions: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa.
The twin rods provide equal force and speed in both directions, superior anti-rotation guidance for the load, and a rear rod end that can mount a cam or sensor flag. It is dimensionally interchangeable per ISO 15552 but requires rear-rod clearance.
