Airtac SDAD Double Rod Slim Cylinder SDAD100X25
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD100X25 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø100mm bore, 25mm stroke). The through-rod resists twisting and lets you drive a tool on one end while a switch or dog reads position on the other — with identical force in both directions.

About the Airtac SDAD Double Rod Slim Cylinder SDAD100X25
The AirTAC SDAD100X25 is a double-acting compact cylinder featuring a 32mm piston rod extending from both ends of its riveted body. Because the rod occupies both chambers, the annular area is identical on extend and retract, yielding an equal push and pull force of 3524.9 N at 0.5 MPa. This symmetry is highly advantageous when driving heavy loads that require consistent dynamics in both travel directions.
Despite the massive 100mm bore, the short body design saves axial mounting depth where a larger profile cylinder would fail to fit. The through-rod geometry inherently resists twisting, allowing you to mount a primary tool on one end and a dog or secondary mechanism on the opposite end. End-of-stroke energy is managed solely by a fixed NBR bumper, which decelerates the piston but is not an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD100X25 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD100X25 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 25 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT3/8 |
| Rod end thread | M18×1.5 female / M26×1.5 male (B) |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| Cushion | Fixed NBR bumper (both ends) |
| Max standard stroke | Up to 120 mm |
Because a rod occupies both cylinder chambers, the effective area — and therefore the force — is identical in both directions. Specifications follow the official AirTAC SDAD datasheet.
Theoretical Output Force (Ø100mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 3525 N |
| 0.7 MPa | 4935 N |
| Max (@1.0 MPa) | 719 kgf |
Force uses the annular (rod-side) area on both strokes, so extend and retract match. Actual usable force is lower than theoretical due to friction. Size with a safety margin.

Where the Airtac SDAD Double Rod Slim Cylinder SDAD100X25 Is Used
Heavy-Duty Web Guiding
Utilizes the 32mm through-rod to resist twisting while providing 3524.9 N of equal bidirectional force for precise tensioning and guiding of thick industrial materials.
Symmetric Lift Stations
Ideal for lifting 179.7 kg vertical loads with a 2:1 margin, where the identical extend and retract dynamics prevent jerky motions during the 25mm travel.
Dual-End Tooling Drive
Mounts a heavy press tool on one end and a mechanical dog on the opposite end, leveraging the compact riveted body to save space in tight machinery.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD100X25 the Right Cylinder?
When sizing this model, compare it against adjacent bores to match your exact load. Stepping down, the SDAD80 provides 2267.8 N at 0.5 MPa, whereas this SDAD100X25 delivers 3524.9 N at 0.5 MPa. For a 2:1 safety margin, the safe working load is approximately 2115 N, capable of a vertical lift around 179.7 kg. If your application requires even more force, this 100mm bore represents the upper limit of the series.
The dual-end through-rod provides excellent anti-rotation stability for heavy fixtures. Note that a plain SDAD does not hold position if air pressure is lost or the valve is centered, as the piston will drift and the fixed bumper only decelerates near the stroke end; use an external rod lock or pilot-operated check valve for load holding. This specific SKU lacks a piston magnet, so it cannot support magnetic switches—select the -S option if reed or electronic sensing is required. It features a 25mm stroke, PT3/8 ports, and female M18x1.5 rod-end threads on both ends.
Quick checklist
- ✓ Need equal force both directions?
- ✓ Anti-rotation / dual-end mounting?
- ✓ Space for a rod that exits both ends
- ✓ Port/thread type (PT)
- ✓ Magnet (S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Leave clearance for the rod exiting both ends.
- check Avoid side load on either rod end.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDAD Double Rod Slim Cylinder SDAD100X25 FAQ
The SDAD100X25 provides equal force in both directions due to the double-rod design. It outputs 3524.9 N at 0.5 MPa, 4934.8 N at 0.7 MPa, and a theoretical maximum of 719 kgf at 1.0 MPa.
No, this specific SKU does not include a piston magnet and cannot support reed or electronic switches. You must select the -S variant to enable magnetic sensing capabilities alongside the dual-end mounting benefits.
