Airtac SED Double Rod Cylinder SED100X140S
The AirTAC Airtac SED Double Rod Cylinder SED100X140S 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 140mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X140S
The AirTAC SED100X140S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a Ø25 mm rod exits both end covers, the effective piston area is identical on extend and retract. This yields exactly 3681 N of output force at 0.5 MPa in both directions, ensuring perfectly balanced motion for heavy loads.
Equipped with a standard magnet (-S), this 100 mm bore unit supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. The extruded aluminum barrel omits external tie rods, while adjustable air cushions at both ends allow you to tune deceleration for 140 mm strokes.

| 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 SED100X140S Is Used
Servo Press Positioning
Drives a heavy stamping head with 3681 N of equal both-way force, using the twin rods to prevent chassis twist during high-tonnage press cycles.
Pallet Transfer Gate
Shifts a 100 mm bore diverter arm across a conveyor line, relying on the through-rod design to mount a cam flag for position confirmation.
Mold Clamping Fixture
Secures heavy injection molds with balanced 5153 N force at 0.7 MPa, leveraging the rigid double-rod guidance to keep halves perfectly aligned.
Is the Airtac SED Double Rod Cylinder SED100X140S the Right Cylinder?
Choose this 100 mm bore when you need substantial equal both-way thrust. If your application requires less force, stepping down to the 80 mm bore provides 2268 N at 0.5 MPa. If you need more power, the 125 mm bore offers 5734 N. The twin-rod design provides superior anti-rotation resistance compared to a single-rod SE cylinder, and the rear rod can drive a secondary mechanism or sensor flag.
For ISO 15552 drop-in replacements, match the 140 mm stroke, PT1/2 port, and preferred mounting from the SED subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the air cushion only decelerates the load near stroke end; it does not hold position on air loss. For fail-safe holding, consider a BSED double-rod rod lock cylinder or an external locking device.
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 SED100X140S FAQ
Because the double-rod design subtracts rod area from both sides, force is equal 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 and allow the rear rod to drive secondary tooling or sensors. It also makes the extend and retract forces perfectly identical, which is critical for precision balancing.
