Airtac SED Double Rod Cylinder SED100X135
The AirTAC Airtac SED Double Rod Cylinder SED100X135 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 135mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X135
The AirTAC SED100X135 is a double-acting, double-rod profile cylinder built to ISO 15552 dimensions. Because a 25mm rod exits both ends, the effective piston area is identical in extend and retract, yielding an equal 3681N of thrust each way at 0.5MPa. The extruded aluminum barrel lacks external tie rods and features adjustable air cushioning at both ends.
This SKU ships without a magnet (-S omitted), meaning no CMSE or DMSE position sensing is possible without modification. The rear rod extension is highly useful for mounting a mechanical cam or driving a secondary mechanism, while simultaneously guiding the load against rotation. With a PT1/2 port and M20x1.5 rod thread, it operates at speeds of 30-800mm/s.
Airtac SED Double Rod Cylinder SED100X135 Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 135 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 SED100X135 Is Used
Web Guiding Press
Provides 3681N of equal bidirectional force to position a paper web guide, using the twin rods to prevent binding and ensure perfectly straight tracking.
Dual-Side Stamping
Drives a 135mm stamping action on a lightweight metal bracket, utilizing the rear rod to simultaneously trigger a mechanical cutoff cam at the same speed.
Pallet Transfer Gate
Shifts a conveyor diverter gate with 5153N at 0.7MPa, relying on the anti-rotation properties of the dual rods to maintain gate alignment.
Is the Airtac SED Double Rod Cylinder SED100X135 the Right Cylinder?
Choose the SED100X135 when your mechanism requires 3681N of bidirectional force at 0.5MPa, or 5153N at 0.7MPa. If your application demands less thrust, step down to the 80mm bore which provides 2268N both ways at 0.5MPa. If you need more power, the 125mm bore offers 5734N both ways. Remember that a plain SED does not hold position on air loss; the piston drifts and the air cushion only decelerates near stroke end. For fail-safe holding, consider a BSED double-rod lock cylinder or an external rod lock.
As a true ISO 15552 profile cylinder, this is a drop-in replacement for any standard ISO 15552 double-rod unit with a 100mm bore, 135mm stroke, PT1/2 port, and compatible mounting. Available mountings include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR styles). At 135mm stroke, side loads are moderate, but always ensure external guides support the load if heavy lateral forces are present.
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 SED100X135 FAQ
Because the double-rod design subtracts rod area from both sides, force is equal in both directions: 3681N at 0.5MPa, 5153N at 0.7MPa, and a maximum of 751kgf at 1.0MPa.
No. The SED100X135 is double-acting and will drift if air pressure is lost; the adjustable air cushion only decelerates near stroke end and is not a lock. For fail-safe holding, use a BSED rod lock cylinder or an external pilot-operated check valve.
