Airtac SED Double Rod Cylinder SED100X145S
The AirTAC Airtac SED Double Rod Cylinder SED100X145S 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 145mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X145S
The AirTAC SED100X145S is a double-acting, double-rod profile cylinder built to the ISO 15552 dimension. A Ø25 mm piston rod exits both end covers, yielding identical annulus areas. This equal-force geometry delivers 3681 N of thrust and pull each way at 0.5 MPa, eliminating directional force mismatch.
Equipped with a standard magnet (-S), the rear rod end can drive a secondary mechanism while triggering CMSE reed or DMSE electronic sensors. The extruded aluminum barrel omits external tie rods, and field-adjustable air cushions at both ends protect your tooling over the 145 mm stroke.
Airtac SED Double Rod Cylinder SED100X145S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X145S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 145 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 SED100X145S Is Used
Servo Press Feeders
Drives material grippers in stamping lines, using the 5153 N both-way force to push and pull stock equally without rotational drift.
Indexing Shuttle Conveyors
Shifts pallets between machining stations where the twin rods prevent binding under offset loads during the 145 mm transfer.
Parts Ejector Systems
Ejects formed parts from hydraulic presses, leveraging the rear rod end to trip a DMSE sensor that times the next machine cycle.
Is the Airtac SED Double Rod Cylinder SED100X145S the Right Cylinder?
At 0.5 MPa, this 100 mm bore generates 3681 N both ways. If your load is lighter, step down to the 80 mm bore for 2268 N; for heavier demands, step up to the 125 mm bore for 5734 N. Choose this twin-rod design over a single-rod SE when you need strict anti-rotation guidance or must mount rear-facing tooling and flags.
Because a rod protrudes from the back cover, leave rear clearance for the extended length. Note that a plain SED drifts on air loss—the adjustable cushion decelerates near stroke end but does not lock position. For fail-safe holding, use a BSED double-rod lock. Replacement match: 100 mm bore, 145 mm stroke, PT1/2 port, -S magnet.
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 SED100X145S FAQ
Because the double-rod design creates equal annulus areas, 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 rods provide superior anti-rotation guidance for heavy tooling and allow the rear rod end to mount cams or sensors. It drops into any ISO 15552 footprint but requires rear-rod clearance.
