Airtac SED Double Rod Cylinder SED100X225S
The AirTAC Airtac SED Double Rod Cylinder SED100X225S 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 225mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X225S
The AirTAC SED100X225S is a double-acting, double-rod profile cylinder operating on the ISO 15552 interface. A 25 mm rod exits both end covers, yielding identical annulus areas. This means you get exactly 3681 N of thrust in both directions at 0.5 MPa.
Because this unit includes the -S magnet, it supports DMSE electronic and CMSE reed sensors for dual-end position tracking. The extruded aluminum barrel avoids external tie rods, and the field-adjustable air cushions at both ends tame heavy 225 mm stroke impacts.
Airtac SED Double Rod Cylinder SED100X225S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X225S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 225 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 SED100X225S Is Used
Servo Press Sub-Assembly
Drives a 3681 N bidirectional press head where the rear rod simultaneously triggers a pneumatic valve, ensuring synchronized timing.
Pallet Transfer Diverter
Shifts heavy pallets with equal push and pull force, using the twin rods to resist torsional twisting during high-speed redirection.
Textile Loom Beam Actuator
Moves heavy warp beams back and forth, relying on the 5153 N both-way output and adjustable cushions to prevent end-of-stroke shock.
Is the Airtac SED Double Rod Cylinder SED100X225S the Right Cylinder?
Select this 100 mm bore when you need 5153 N of equal bidirectional force at 0.7 MPa. If your payload is lighter, step down to the 80 mm bore (2268 N at 0.5 MPa). For heavier drives, the 125 mm bore provides 5734 N at 0.5 MPa.
A double-rod design gives superior anti-rotation control and lets the rear rod drive a secondary mechanism. Plain SED cylinders drift on air loss, so specify a BSED rod-lock variant for fail-safe holding. Since the stroke is 225 mm, ensure external guides manage side loads to protect the M20x1.5 rod threads. Mounting options are Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SED100X225S FAQ
The SED100X225S provides equal force in both directions due to its double-rod design. It outputs 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and reaches a maximum of 751 kgf at 1.0 MPa.
Yes. The SED100X225S matches ISO 15552 mounting dimensions, allowing drop-in replacement for any standard 100 mm double-rod profile cylinder. Just match your port (PT1/2) and mounting style.
