Airtac SED Double Rod Cylinder SED100X140
The AirTAC Airtac SED Double Rod Cylinder SED100X140 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 140mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X140
The AirTAC SED100X140 is a double-acting, double-rod profile cylinder fully dimensionally interchangeable per ISO 15552. A 25mm rod exits both end covers, yielding identical annulus areas. This equal-force design delivers exactly 3681 N of thrust and pull at 0.5 MPa, and 5153 N at 0.7 MPa.
Because the rear rod protrudes alongside the front, you can mount a secondary cam or sensor flag directly opposite the primary work tool. The extruded aluminum barrel incorporates standard sensor grooves, though this specific SKU ships without a magnet, precluding direct CMSE or DMSE position sensing. Adjustable air cushions at both ends absorb impact near the 140mm stroke limits.
Airtac SED Double Rod Cylinder SED100X140 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X140 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 140 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 SED100X140 Is Used
Multi-Station Indexing Press
Drives a 3681 N clamping plate at 0.5 MPa that must push and retract with identical force, using the rear rod to trip a mechanical stop on a dial index table.
Heavy Pallet Transfer Gate
Lifts and lowers a 100mm bore diverter gate; the twin rods prevent the heavy 5153 N load from twisting during high-speed 30-800 mm/s actuation.
Tandem Web Splicer
Applies equal 3681 N tension from both rod ends to hold a paper web splice, leveraging the through-rod design to operate a secondary knife cam.
Is the Airtac SED Double Rod Cylinder SED100X140 the Right Cylinder?
Choosing this 100mm bore yields 3681 N both ways at 0.5 MPa. If your fixture is over-specified, the 80mm bore drops output to 2268 N. If you need more push, the 125mm bore jumps to 5734 N. The twin-rod architecture inherently resists torsional rotation better than a single-rod SE cylinder, making it ideal for synchronized dual-side loads.
Remember that a standard SED relies on air pressure to hold position; it will drift downward if air supply is lost. For fail-safe holding, specify a BSED double-rod rod-lock cylinder. When swapping an ISO 15552 unit, match the 100mm bore, 140mm stroke, PT1/2 port, and preferred mounting from the SED 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 SED100X140 FAQ
Because the double-rod design creates equal effective piston areas on both sides, the SED100X140 outputs 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa in both extend and retract directions.
Yes. It is a true ISO 15552 profile cylinder with no external tie rods. You can drop it in for any standard 100mm bore, 140mm stroke ISO 15552 double-rod unit, provided you use the PT1/2 port and compatible SED mounting hardware.
