Airtac SED Double Rod Cylinder SED100X650
The AirTAC Airtac SED Double Rod Cylinder SED100X650 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 650mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X650
The AirTAC SED100X650 is a double-acting, double-rod profile cylinder built to the ISO 15552 / VDMA 24562 dimensional interface. A Ø25 mm rod exits both end covers, yielding exactly 3681 N of thrust at 0.5 MPa in both extend and retract directions. The extruded aluminum barrel omits external tie rods, and standard field-adjustable air cushions at both ends decelerate the 650 mm travel near stroke end.
This SKU ships without a magnet (-S), so it cannot host CMSE reed or DMSE electronic sensors without modification. The rear rod extension is ideal for mounting a cam or driving a secondary mechanism, while the twin rods provide superior anti-rotation guidance. The PT1/2 port and M20x1.5 rod thread handle high flow and heavy loads up to 751 kgf at 1.0 MPa.
Airtac SED Double Rod Cylinder SED100X650 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X650 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 650 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 SED100X650 Is Used
Pallet Transfer System
Drives a 650 mm pallet transfer carriage with 5153 N both ways at 0.7 MPa, using the twin rods to prevent load rotation during rapid indexing.
CNC Lathe Loader
Actuates a 100 mm bore bar feeder through the rear rod, delivering equal 3681 N push and pull force at 0.5 MPa for symmetric part loading and unloading.
Heavy-Duty Press Cam
Uses the extended rear rod to trip a sequence valve cam on a 650 mm press cycle, handling up to 751 kgf at 1.0 MPa without deflection.
Is the Airtac SED Double Rod Cylinder SED100X650 the Right Cylinder?
Select this 100 mm bore when you need 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 your application requires equal push/pull force, dual-side guidance, or rear-rod tooling. Note that a plain SED does not hold position on air loss—the piston drifts, and the air cushion is not a lock. For fail-safe hold, consider a BSED double-rod rod lock.
At 650 mm of stroke, the extended rod length demands external load guides to prevent side-loading damage to the seals. As a true ISO 15552 cylinder, it drops in for any standard 100 mm double-rod footprint. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Ensure rear-rod clearance, as overall length is longer than a single-rod SE.
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 SED100X650 FAQ
Because a rod exits both ends, the effective piston area is identical in both directions. The SED100X650 generates 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 strokes.
No. A standard SED cylinder will drift if air pressure is lost. The adjustable air cushion only decelerates the piston near the end of stroke; it is not a brake. For fail-safe position holding, use a BSED double-rod rod lock cylinder or an external pilot-operated check valve.
