Airtac SED Double Rod Cylinder SED100X25S
The AirTAC Airtac SED Double Rod Cylinder SED100X25S 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 25mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X25S
The AirTAC SED100X25S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 25mm stroke. Because a 25mm rod occupies both sides of the piston, the effective annular area is identical in both directions, yielding an equal drive force of 3681 N at 0.5 MPa on extend and retract. The extruded aluminum barrel includes sensor grooves, and this -S variant includes a magnet for CMSE reed or DMSE electronic position sensing.
This through-rod design allows the rear rod end to drive a secondary mechanism or mount a limit flag, while simultaneously improving load guidance against rotation. Field-adjustable air cushions at both ends decelerate the 30-800 mm/s motion near stroke end, and the PT1/2 port matches the standard ISO 15552 mounting interface.

| Bore size | Ø100 mm |
| Stroke | 25 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 SED100X25S Is Used
Servo Press Feeders
Drives gripper slides in servo press lines, utilizing the 3681 N both-way force and twin-rod anti-rotation to push and retract heavy coil stock without binding.
Pallet Transfer Rejects
Uses the rear rod end to actuate a cam diverter on a packaging conveyor while the front rod pushes the product, leveraging equal 5153 N force at 0.7 MPa for dual-side work.
Injection Mold Ejectors
Ejects molded parts from heavy tooling, where the double-rod design supports the load evenly and the M20x1.5 threads mount custom knock-out plates securely.
Is the Airtac SED Double Rod Cylinder SED100X25S the Right Cylinder?
Selecting this 100mm bore provides a balanced 3681 N both-way force at 0.5 MPa. If your application requires less thrust, the 80mm bore steps down to 2268 N both ways at 0.5 MPa; if you need more power, the 125mm bore steps up to 5734 N. The twin-rod architecture is preferred over a single-rod SE when you need dual-side guidance, anti-rotation stability, or rear-rod tooling. To replace an ISO 15552 unit, match the 100mm bore, 25mm 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; for fail-safe holding, use a BSED rod lock or 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 SED100X25S FAQ
Because the double-rod design has equal piston areas on both sides, the output 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-rod design provides equal force both ways, better load stability against rotation, and a rear rod end for mounting sensors or secondary tooling. It drops into standard ISO 15552 footprints using Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts, but requires rear-rod clearance.
