Airtac SED Double Rod Cylinder SED100X120
The AirTAC Airtac SED Double Rod Cylinder SED100X120 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 SED100X120
The AirTAC SED100X120 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100 mm bore and 120 mm stroke. Because a 25 mm rod exits both end covers, the effective piston area is identical on extend and retract. This yields an equal both-way force of 3681 N at 0.5 MPa, ensuring perfectly balanced thrust for demanding push-pull cycles.
This extruded aluminum profile cylinder omits external tie rods and integrates field-adjustable air cushioning at both ends over a 36 mm stroke. It uses a PT1/2 port and M20x1.5 rod threads. Note that this specific SKU lacks a standard magnet (-S), meaning it does not directly support CMSE or DMSE position sensing without modification.
Airtac SED Double Rod Cylinder SED100X120 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X120 |
|---|---|
| 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 SED100X120 Is Used
Servo Press Dampening
Drives a heavy servo press dampener. The twin rods handle 5153 N at 0.7 MPa equally in both directions, absorbing shock while keeping the tooling perfectly aligned.
Pallet Diverting Arm
Powers a 100 mm stroke pallet diverting arm on a high-speed packaging conveyor. The rear rod end mounts a cam to trigger external switches without extra brackets.
Heavy Mold Transfer
Shifts heavy injection molds between stations. The double-rod design prevents torsional twist under the 751 kgf maximum load, ensuring smooth horizontal transit.
Is the Airtac SED Double Rod Cylinder SED100X120 the Right Cylinder?
Select this 100 mm bore when your mechanism requires substantial, perfectly symmetrical thrust. It generates 3681 N each way at 0.5 MPa. If you need less force, the 80 mm SED provides 2268 N; if you require more, the 125 mm SED offers 5734 N. This sizing is ideal for driving heavy slides or external mechanisms from the rear rod end, which also provides superior anti-rotation guidance compared to a single-rod SE cylinder.
As a true ISO 15552 cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod profile cylinders. When ordering, confirm your 120 mm stroke, PT1/2 port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Remember that a plain SED does not hold position on air loss; for fail-safe holding, consider a BSED double-rod rod lock cylinder.
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 SED100X120 FAQ
Because the double-rod design has equal piston area 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 both ways and superior anti-rotation guidance. The rear protruding rod can mount a cam or drive a secondary mechanism, which a single-rod SE cannot do. It uses the same ISO 15552 mounting footprint.
