Airtac SED Double Rod Cylinder SED100X230S
The AirTAC Airtac SED Double Rod Cylinder SED100X230S 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 230mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X230S
The AirTAC SED100X230S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a 25 mm rod exits both end covers, the effective piston area is identical on extend and retract. This delivers exactly 3681 N of force each way at 0.5 MPa, eliminating directional force mismatch.
Equipped with a standard magnet (-S), the rear rod extension can host a DMSE electronic sensor or CMSE reed switch for end-of-stroke confirmation. The extruded aluminum barrel lacks external tie rods, and field-adjustable air cushions at both ends absorb kinetic energy at stroke completion.

| Stroke | 230 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 |

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 SED100X230S Is Used
Servo Press Bed Leveling
Uses the 5153 N equal both-way force to clamp and symmetrically adjust heavy servo press beds, relying on the twin rods to prevent bed twisting during high-tonnage cycles.
Pallet Transfer Diversion
Drives a dual-sided diverter arm on a 1000 kg capacity packaging conveyor, using the rear rod to physically trip a mechanical limit flag upon full extension.
Injection Mold Ejection
Actuates a synchronized ejection plate in an injection molding machine, where the balanced 3681 N thrust at 0.5 MPa ensures parallel plate movement without binding.
Is the Airtac SED Double Rod Cylinder SED100X230S the Right Cylinder?
Stepping up to the 125 mm bore yields 5734 N both ways at 0.5 MPa, while dropping to the 80 mm bore provides 2268 N. Choose this 100 mm bore when your mechanism requires over 3500 N of balanced thrust in both directions. The twin-rod architecture provides superior anti-rotation stability and allows the rear rod to drive a secondary mechanism or cam.
For drop-in replacement, match the 100 mm bore, 230 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 will drift. For fail-safe holding, use an external pilot-operated check valve or select a BSED double-rod rod lock cylinder. At 230 mm stroke, ensure external load guides are used to prevent side-loading damage to the rod seals.
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 SED100X230S FAQ
Because the double-rod design has equal piston area on both sides, it provides 3681 N of force at 0.5 MPa and 5153 N at 0.7 MPa in both directions. The maximum force is 751 kgf at 1.0 MPa.
The twin 25 mm rods provide high resistance to side loads and prevent piston rotation, allowing the rear rod to drive a secondary mechanism. It is dimensionally interchangeable per ISO 15552, but offers equal push and pull forces.
