Airtac SED Double Rod Cylinder SED100X850S
The AirTAC Airtac SED Double Rod Cylinder SED100X850S 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 850mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X850S
The AirTAC SED100X850S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. A 25 mm rod exits both end covers, yielding an identical annulus area on each side. This design provides equal force in both directions, generating about 3681 N at 0.5 MPa and 5153 N at 0.7 MPa on extend and retract.
Equipped with a standard magnet (-S), it supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. The extruded aluminum barrel lacks external tie rods, and the field-adjustable air cushioning at both ends safely decelerates the 850 mm stroke. The rear rod extension can drive a secondary mechanism or mount a cam.
Airtac SED Double Rod Cylinder SED100X850S Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 850 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 SED100X850S Is Used
Pallet Transfer Drives
Drives large pallets across conveyor lanes. The 5153 N equal both-way force and twin-rod anti-rotation stability keep heavy loads aligned during 850 mm transfers.
Board Pressing Arms
Presses large composite boards. The rear rod can mount a cam to trigger a secondary glue dispenser, while the front rod applies 3681 N of clamping force.
Automated Welding Gates
Actuates heavy welding chamber gates. The 100 mm bore provides high thrust, and the -S magnet works with DMSE sensors to confirm gate closure in harsh environments.
Is the Airtac SED Double Rod Cylinder SED100X850S the Right Cylinder?
This 100 mm bore generates 3681 N both ways at 0.5 MPa. If your load is lighter, the 80 mm bore provides 2268 N both ways; if you need more power, the 125 mm bore offers 5734 N both ways. Choose this double-rod SED over a single-rod SE when an application requires dual-side guidance, anti-rotation control, or rear-rod tooling.
At 850 mm stroke, the extended rod is highly susceptible to side loads. Always use external guide rails to prevent binding and premature seal wear. For drop-in replacements, match the 100 mm bore, 850 mm stroke, PT1/2 port, and mounting interface (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that a plain SED does not hold position on air loss; for fail-safe holding, consider a BSED rod-lock cylinder.
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 SED100X850S FAQ
Because the rod exits both ends, the force is identical 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.
The twin-rod design prevents piston rotation and allows the rear rod to drive a secondary mechanism or sensor flag. It is dimensionally interchangeable with other ISO 15552 profile cylinders.
