Airtac SED Double Rod Cylinder SED100X200S
The AirTAC Airtac SED Double Rod Cylinder SED100X200S 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 200mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X200S
The AirTAC SED100X200S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. A single piston drives a Ø25 mm rod out of both end covers, yielding identical annulus areas. This means output force is perfectly symmetrical, generating 3681 N each way at 0.5 MPa and 5153 N at 0.7 MPa.
Equipped with a standard magnet (-S), the rear rod extension is fully exposed to mount a CMSE reed or DMSE electronic sensor flag, or to drive a secondary mechanism. The extruded aluminum barrel lacks external tie-rods, and field-adjustable air cushions at both ends decelerate the 30-800 mm/s motion near stroke ends without locking the load.
Airtac SED Double Rod Cylinder SED100X200S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X200S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 200 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 SED100X200S Is Used
Servo Press Sub-Assembly
Drives a twin-sided stamping head with 5153 N at 0.7 MPa, using the rear rod to mount a linear transducer for precise position feedback.
Pallet Transfer Pusher
Pushes heavy pallets equally well in extend and retract strokes, leveraging the double rod's anti-rotation properties to prevent load jamming.
Automated Welding Gripper
Actuates a dual-arm gripper carrying welding torches, where the symmetrical 3681 N force at 0.5 MPa ensures consistent clamping pressure both ways.
Is the Airtac SED Double Rod Cylinder SED100X200S the Right Cylinder?
Choose this 100 mm bore when your application requires 3681 N of equal bidirectional force at 0.5 MPa. If your payload is lighter, step down to the 80 mm bore for 2268 N. For heavier drives, the 125 mm bore offers 5734 N. The double-rod design is preferred over a single-rod SE when you need superior anti-rotation resistance or must mount rear-side tooling.
A plain SED does not hold position on air loss; the piston drifts, and the adjustable cushion only decelerates near stroke end. For fail-safe holding, consider a BSED double-rod lock. To replace an existing ISO 15552 unit, match the 200 mm stroke, PT1/2 port, M20x1.5 rod thread, and your mounting choice from 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 SED100X200S FAQ
Because the double-rod design creates equal piston areas on both sides, force is identical in both directions: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa.
The SED100X200S provides better load guidance and anti-rotation resistance than a single-rod SE cylinder. The protruding rear rod is ideal for mounting external sensors or driving a secondary mechanism, while maintaining a standard ISO 15552 mounting interface.
