Airtac SED Double Rod Cylinder SED100X175S
The AirTAC Airtac SED Double Rod Cylinder SED100X175S 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 175mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X175S
The AirTAC SED100X175S is a double-acting, double-rod profile cylinder built to the ISO 15552 interface. A 25 mm rod exits both end covers, yielding an identical annulus area on both sides. This means you get equal force in both directions—about 3681 N each way at 0.5 MPa. The extruded aluminum barrel has no external tie rods, ensuring a clean profile.
This unit includes the -S magnet option for position sensing with CMSE reed or DMSE electronic sensors. Field-adjustable air cushions at both ends decelerate the load near stroke end. The rear rod extension can drive a secondary mechanism or mount a cam, providing superior anti-rotation guidance for heavy loads.
Airtac SED Double Rod Cylinder SED100X175S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X175S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 175 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 SED100X175S Is Used
Lift Station Transfer
Drives a 3681 N lifting jig where the rear rod simultaneously pushes a secondary packaging ram, ensuring perfectly synchronized motion without external linkage.
Pallet Diverting
Handles heavy pallet routing using equal 5153 N force at 0.7 MPa, leveraging the twin rods to prevent binding during high-speed 30-800 mm/s diverting strokes.
Press Ejection
Ejects stamped metal parts from a die while the rear rod triggers a mechanical flag, using the 751 kgf max output to reliably clear heavy blanks.
Is the Airtac SED Double Rod Cylinder SED100X175S the Right Cylinder?
Choose this 100 mm bore when you need substantial, balanced thrust. Stepping down to the 80 mm bore drops the both-way force to 2268 N at 0.5 MPa, while stepping up to the 125 mm bore increases it to 5734 N. The twin-rod design is essential over a single-rod SE when your application requires anti-rotation stability or rear-end tooling. A plain SED does not hold position on air loss; the piston will drift. For fail-safe holding, use a BSED double-rod rod lock cylinder. To replace an ISO 15552 unit, match the 175 mm stroke, PT1/2 port, and mounting choice (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 SED100X175S FAQ
Because the double-rod design has equal piston areas on both sides, force is identical in extend and retract. 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 SED100X175S offers equal force and speed in both directions, which is vital for symmetrical processes. The rear protruding rod can mount a sensor cam or drive a secondary mechanism, and the twin rods provide superior anti-rotation resistance for heavy tooling.
