Airtac SED Double Rod Cylinder SED100X115S
The AirTAC Airtac SED Double Rod Cylinder SED100X115S 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 SED100X115S
The AirTAC SED100X115S is a double-acting, double-rod ISO 15552 profile cylinder. Because a 25 mm rod exits both end covers, the effective piston area is identical on extend and retract, yielding an equal force of 3681 N each way at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, ensuring a clean ISO 15552 footprint.
This 100 mm bore unit travels 115 mm and includes an -S magnet for CMSE reed or DMSE electronic sensors. Field-adjustable air cushions at both ends decelerate the load near stroke end, while the rear rod extension can mount a cam or secondary mechanism.
Airtac SED Double Rod Cylinder SED100X115S 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 SED100X115S Is Used
CNC Fixture Clamping
Clamps heavy cast iron blocks during machining. The 5153 N both-way force at 0.7 MPa securely holds the part, while the twin rods prevent chassis rotation under heavy milling cuts.
Pallet Diverting Gate
Indexes heavy timber pallets between parallel packaging lines. The rear rod drives a secondary cam mechanism, and the equal extend and retract speeds maintain a steady conveyor rhythm.
Injection Mold Ejection
Ejects dense plastic bins from injection molds. The protruding rear rod safely mounts an external position flag, and the 36 mm adjustable cushion smoothly stops the 751 kgf max load.
Is the Airtac SED Double Rod Cylinder SED100X115S the Right Cylinder?
Select this 100 mm bore when you need 5153 N of both-way thrust at 0.7 MPa. If your application requires less force, step down to the 80 mm bore providing 2268 N at 0.5 MPa. If you need more thrust, the 125 mm bore offers 5734 N at 0.5 MPa. Choose this double-rod SED over a single-rod SE when you need anti-rotation guidance, rear-rod tooling, or equal push and pull dynamics.
For drop-in replacement, match the 100 mm bore, 115 mm stroke, PT1/2 port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that a plain SED does not hold position on air loss; the piston drifts. For fail-safe holding, use 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 SED100X115S FAQ
Because the double-rod design subtracts rod area on both sides, force is equal in both directions. It provides 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 superior anti-rotation guidance and equal force both ways. The rear rod can drive a secondary mechanism or sensor flag. It also uses a subset of ISO 15552 mounts (Basic, FA, LB, TC, FTC, TCM1, TCM2) and requires rear-rod clearance.
