Airtac SED Double Rod Cylinder SED100X500S
The AirTAC Airtac SED Double Rod Cylinder SED100X500S 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 500mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X500S
The AirTAC SED100X500S is a double-acting, double-rod profile cylinder built to the ISO 15552 interface. Because a 25mm rod exits both end covers, the effective piston area is identical on extend and retract, yielding an equal force of 3681 N each way at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, ensuring a clean exterior while providing field-adjustable air cushioning at both ends to decelerate the 500mm stroke.
This unit includes the -S magnet option for position sensing via CMSE reed or DMSE electronic switches. The protruding rear rod can drive a secondary mechanism or mount a limit flag, while the twin-rod geometry inherently resists torsional rotation under offset loads.

| Bore size | Ø100 mm |
| Stroke | 500 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 SED100X500S Is Used
Servo-Press Ejection
Drives a double-sided ejection array in a metal stamping press, using the equal 3681 N force to cleanly strip parts without reversing load bias.
Pallet Transfer Gate
Actuates a heavy diverter gate on a packaging conveyor, utilizing the rear rod end to mount a physical cam that triggers a mechanical stop.
Synchronized Lift Fixture
Lifts and lowers a 300kg machining fixture, relying on the twin rods' anti-rotation properties to keep the precision tooling perfectly aligned.
Is the Airtac SED Double Rod Cylinder SED100X500S the Right Cylinder?
At 0.5 MPa, this 100mm bore generates 3681 N in both directions. If your payload is lighter, the 80mm bore offers 2268 N both ways; for heavier thrust, the 125mm bore provides 5734 N. The twin-rod design suits mechanisms needing symmetrical push-pull force, rear-rod tooling, or superior anti-rotation guidance compared to a single-rod SE cylinder. An SED relies on air pressure to hold position and will drift if air is lost; its adjustable cushion only decelerates near stroke end, so for fail-safe holding, consider a BSED double-rod lock. For a 500mm stroke, external guide rails are recommended to prevent side-load wear on the rod seals. When replacing an ISO 15552 cylinder, match the 100mm bore, 500mm stroke, PT1/2 port, and mounting style (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 SED100X500S FAQ
Because the double-rod design subtracts the rod area from both sides, force is equal 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 twin rods provide identical extend and retract forces, superior resistance to torsional rotation, and a rear rod end that can drive a secondary mechanism or sensor flag. It also omits certain mountings like FB and CA, focusing on ISO 15552 interfaces like TC and FA.
