Airtac SED Double Rod Cylinder SED100X5
The AirTAC Airtac SED Double Rod Cylinder SED100X5 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 5mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X5
The AirTAC SED100X5 is a double-acting, double-rod ISO 15552 profile cylinder engineered for high-force, short-stroke linear motion. Because a Ø25 mm rod occupies both sides of the piston, the annulus area is identical in both directions. This yields an equal force of 3681 N at 0.5 MPa on extend and retract, preventing directional force mismatch.
The extruded aluminum barrel contains no external tie rods, ensuring a clean profile that drops in dimensionally for any ISO 15552 mounting interface. This specific SKU lacks the -S magnet option, meaning it carries no onboard position sensing. Field-adjustable air cushions at both ends provide tailored deceleration for this 5 mm stroke, while the rear rod end can drive a secondary mechanism or carry a tooling flag.

| 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 SED100X5 Is Used
Precision Pressing
Delivers 3681 N of equal both-way force for stamping small metal inserts in a 5 mm travel, using the rear rod to sync a return cam.
Heavy-Duty Clamping
Holds thick steel plates during machining; the twin rods prevent rotational twist under offset loads up to 751 kgf max.
Dual-Side Ejection
Ejects molded parts from both sides of a fixture simultaneously, ensuring balanced ejection without requiring two single-rod cylinders.
Is the Airtac SED Double Rod Cylinder SED100X5 the Right Cylinder?
Select this 100 mm bore when you need substantial equal both-way thrust for compact 5 mm movements, such as clamping or pressing. If your application requires less force, stepping down to the 80 mm bore provides 2268 N at 0.5 MPa. If you need maximum push-pull capacity, the 125 mm bore yields 5734 N at 0.5 MPa. Because the stroke is extremely short, side loading is minimal, but the twin-rod design inherently resists torsion better than a single-rod SE cylinder.
A plain SED does not hold position on air loss; the piston will drift without pressure. The adjustable air cushion only decelerates near the stroke end and is not a mechanical lock. For fail-safe holding, consider a BSED double-rod rod lock or an external pilot-operated check valve. When replacing an existing ISO 15552 unit, match the 100 mm bore, 5 mm stroke, PT1/2 port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, 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 SED100X5 FAQ
Because the double-rod design subtracts the rod area from both sides, force is equal in both directions. It provides 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa.
A double-rod cylinder provides identical force and speed in both directions, offers better anti-rotation guidance for the load, and allows you to mount a sensor flag or secondary tooling on the rear rod end.
