Airtac SED Double Rod Cylinder SED100X275
The AirTAC Airtac SED Double Rod Cylinder SED100X275 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 275mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X275
The AirTAC SED100X275 is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a rod exits both ends, the annulus area is identical on extend and retract. It delivers an equal 3681 N of force in both directions at 0.5 MPa.
This extruded aluminum barrel omits external tie rods and includes adjustable air cushioning at both ends. This specific SKU lacks a magnet, meaning no position sensing is available. The rear rod protrusion allows you to mount a cam or secondary mechanism while guiding the load against rotation.

| 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 |

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 SED100X275 Is Used
Press Die Ejection
Drives upper and lower ejector pins simultaneously in a 100-ton press. The equal 5153 N both-way force at 0.7 MPa ensures balanced part release without rotational drift.
Pallet Transfer Gate
Diverts heavy 500kg pallets between parallel roller lines. The rear rod operates a mechanical cam to trigger the next conveyor stage, utilizing the 3681 N bidirectional thrust.
Glass Panel Lifter
Lifts and lowers large glass sheets in an assembly jig. Twin rods prevent the heavy gripper assembly from twisting during the 275mm vertical traverse.
Is the Airtac SED Double Rod Cylinder SED100X275 the Right Cylinder?
Choose this 100mm bore when you need 5153 N of bidirectional force at 0.7 MPa. If you need less power, step down to the 80mm bore for 2268 N at 0.5 MPa. If your application requires more thrust, the 125mm bore provides 5734 N at 0.5 MPa. At 275mm stroke, the twin rods improve stability but you must use external guides to manage side loads.
A double-rod design gives superior anti-rotation control compared to a single-rod SE cylinder. Remember that a plain SED drifts on air loss; the air cushions only decelerate near stroke end and do not lock position. For fail-safe holding, use an external rod lock or a BSED cylinder. When replacing an ISO 15552 unit, match the PT1/2 port, 275mm stroke, and mounting style.
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 SED100X275 FAQ
Because the rod occupies both sides of the piston, force is identical in both directions. 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. As an ISO 15552 profile cylinder, it drops in for any standard double-rod unit with a 100mm bore and 275mm stroke. Just match your mounting hardware (Basic, FA, LB, TC, FTC, TCM1, or TCM2) and the PT1/2 port.
