Airtac SED Double Rod Cylinder SED100X165
The AirTAC Airtac SED Double Rod Cylinder SED100X165 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 SED100X165
The AirTAC SED100X165 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 force each way at 0.5 MPa.
This unit features an extruded aluminum barrel with no external tie rods. It includes field-adjustable air cushioning at both ends (36 mm stroke) to manage deceleration. Note that this specific SKU lacks a piston magnet, so it cannot host CMSE or DMSE position sensors.
Airtac SED Double Rod Cylinder SED100X165 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 SED100X165 Is Used
Servo Press Platen
Drives a 5153 N stamping platen where the twin rods prevent torsional deflection during high-impact precision metal forming.
Pallet Transfer Gate
Actuates a heavy diverter gate on a packaging line, using the equal both-way force to reliably push and retract 751 kgf loads.
Indexing Drum Cam
Powers a rotary indexer cam where the extended rear rod mechanically trips a mechanical limit valve without electronic sensors.
Is the Airtac SED Double Rod Cylinder SED100X165 the Right Cylinder?
Select this 100 mm bore when an application demands 5153 N of equal bidirectional force at 0.7 MPa. If you need less output, step down to the 80 mm bore (2268 N at 0.5 MPa). If you require more, the 125 mm bore provides 5734 N at 0.5 MPa.
Choose this double-rod configuration over a single-rod SE when you need superior anti-rotation guidance or wish to mount a rear cam. Remember that a plain SED drifts on air loss; for fail-safe holding, use a BSED or external lock. To replace an ISO 15552 unit, match the 165 mm stroke, PT1/2 port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, or 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 SED100X165 FAQ
The drive force is equal in both directions due to the double-rod design. 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.
The twin-rod design provides superior load guidance and prevents piston rotation. It also allows the rear rod to drive a secondary mechanism. Remember to leave rear-rod clearance, as the overall length is longer than a single-rod cylinder.
