Airtac SED Double Rod Cylinder SED100X115
The AirTAC Airtac SED Double Rod Cylinder SED100X115 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 115mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X115
The AirTAC SED100X115 is a double-acting, double-rod profile cylinder built to ISO 15552 dimensions. Because a 25 mm rod exits both end covers, the effective piston area is identical on extend and retract. This gives you exactly 3681 N of force each way at 0.5 MPa, eliminating speed and force mismatch between directions.
This unit uses an extruded aluminum barrel with no external tie rods and features field-adjustable air cushioning at both ends to tame end-of-stroke impacts. Note this specific SKU lacks a piston magnet, so it cannot host CMSE or DMSE position sensors without modification. The rear rod extension is perfect for mounting a cam or driving a secondary mechanism.
Airtac SED Double Rod Cylinder SED100X115 Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 115 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 SED100X115 Is Used
Multi-Spindle Drilling Heads
Drives dual spindle blocks with 5153 N at 0.7 MPa. The twin 25 mm rods prevent rotational torque from skewing the drill array during the plunge.
Pallet Transfer Pushers
Shifts heavy pallets using 751 kgf max force. The rear rod simultaneously actuates a diverter flag, sequencing the conveyor logic without extra valves.
Press Demolding Arms
Extracts molded parts from presses with equal 3681 N force in both directions, ensuring positive ejection and a controlled retraction cycle.
Is the Airtac SED Double Rod Cylinder SED100X115 the Right Cylinder?
Step down to an 80 mm bore if you only need 2268 N at 0.5 MPa, or step up to a 125 mm bore for 5734 N if your payload demands more mass. Choose this 100 mm double-rod over a single-rod SE when your application requires high resistance to torsional side loads, simultaneous dual-side actuation, or rear-rod tooling. For drop-in replacement, match the 100 mm bore, 115 mm stroke, PT1/2 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that SED mounts omit the FB, CA, CB, and CR options. A plain SED will drift on air loss; use a BSED or external rod lock for fail-safe holding.
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 SED100X115 FAQ
Because the rod occupies both sides of the piston, force is equal 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-rod design provides superior anti-rotation guidance and allows the rear rod to drive a secondary mechanism or sensor flag. It is dimensionally interchangeable per ISO 15552, but note the overall length is longer to accommodate the rear rod.
