Airtac SED Double Rod Cylinder SED100X175
The AirTAC Airtac SED Double Rod Cylinder SED100X175 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 SED100X175
The AirTAC SED100X175 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 175mm stroke. A piston rod extends from both end covers, yielding an identical annulus area on both sides. This geometry produces exactly 3681 N of thrust in both extend and retract directions at 0.5 MPa, eradicating the push-pull force differential found in single-rod units.
Built on an extruded aluminum barrel without external tie rods, it drops directly into standard ISO 15552 mounting interfaces. The rear rod protrusion can drive a secondary mechanism or carry a cam. Note this specific SKU lacks a magnet (-S), meaning no CMSE or DMSE sensors can be fitted for position detection.
Airtac SED Double Rod Cylinder SED100X175 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X175 |
|---|---|
| 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 SED100X175 Is Used
Servo Press Platen
Drives a precision stamping platen requiring 3681 N of equal force in both directions to form sheet metal and retract smoothly without rotational drift.
Pallet Transfer Gate
Actuates a heavy diverter gate on a packaging conveyor, using the twin rods to maintain strict parallel alignment under high side-loading.
Welding Head Lowering
Lowers a robotic spot-welding head with identical extend and retract speeds, while the rear rod end mounts a physical limit flag for machine timing.
Is the Airtac SED Double Rod Cylinder SED100X175 the Right Cylinder?
Select this 100mm bore when your application requires substantial equal bidirectional force. Stepping down to the 80mm bore drops the output to 2268 N at 0.5 MPa, while stepping up to the 125mm bore raises it to 5734 N. The twin-rod design provides superior anti-rotation stability and dual-side guidance compared to a single-rod SE cylinder, making it optimal for heavy lifting or pressing. Remember that the adjustable air cushions only decelerate near stroke end; they do not hold position on air loss. For fail-safe holding, consider a BSED rod-lock cylinder or external check valve. Match your replacement by verifying the 175mm 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 SED100X175 FAQ
Because the rod occupies both sides of the piston, 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 operational speed range is 30-800 mm/s.
Yes. The SED100X175 uses an extruded aluminum profile barrel with standard ISO 15552 / VDMA 24562 mounting dimensions, making it a drop-in replacement. Just ensure your mounting style is supported (Basic, FA, LB, TC, FTC, TCM1, TCM2) and leave rear-rod clearance.
