Airtac SED Double Rod Cylinder SED100X165S
The AirTAC Airtac SED Double Rod Cylinder SED100X165S 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 165mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X165S
The AirTAC SED100X165S is a double-acting, double-rod profile cylinder built to the ISO 15552 dimensional interface. Because a 25mm rod exits both end covers, the effective piston area is identical on extend and retract. This yields exactly 3681 N of force each way at 0.5 MPa, eliminating the speed and force mismatch found in single-rod units.
The extended rear rod provides a second mounting point for tooling or a DMSE electronic sensor flag. Extruded aluminum construction with field-adjustable air cushions at both ends manages heavy 751 kgf loads smoothly. The included magnet (-S) supports position detection.
Airtac SED Double Rod Cylinder SED100X165S Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 165 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 SED100X165S Is Used
Servo Press Platen
Drives a 3681 N stamping platen where the twin rods prevent torsional deflection during precision metal forming.
Glass Panel Transfer
Shifts heavy glass sheets between conveyors, using the equal both-way force to push and pull without speed mismatch.
Injection Mold Ejector
Uses the rear rod end to trigger a DMSE electronic sensor flag, confirming full 165mm retraction before the mold closes.
Is the Airtac SED Double Rod Cylinder SED100X165S the Right Cylinder?
Choose this 100mm bore when your application requires 3681 N both ways at 0.5 MPa. If you need less force, the 80mm bore provides 2268 N both ways; stepping up is not possible as 100mm is the second largest standard size. The twin-rod design inherently resists torsion and side loads better than a single-rod SE cylinder, making it ideal for lifting heavy parallel loads.
To replace an existing ISO 15552 cylinder, match the 165mm stroke, PT1/2 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that a plain SED will drift on air loss; for fail-safe holding, specify a BSED rod-lock version or an external pilot check valve.
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 SED100X165S FAQ
Because the double-rod design has equal piston area on both sides, it outputs 3681 N 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 rods provide equal force and speed in both directions, prevent rotation under offset loads, and offer a rear rod end for mounting secondary tooling or sensor flags. It uses the same ISO 15552 mounting footprint as the SE series.
