Airtac SDAD Double Rod Slim Cylinder SDAD25X75
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD25X75 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø25mm bore, 75mm 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 SDAD25X75
The AirTAC SDAD25X75 is a double-acting compact cylinder featuring a 10mm through-rod that exits both ends of the riveted body. Because the rod occupies both chambers, the annular area remains identical in each direction, giving you exactly 206.2N of push and pull force at 0.5MPa. This symmetry prevents twisting and simplifies balancing for vertical or horizontal loads.
The short body design minimizes axial mounting depth where space is tight. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. With a 75mm stroke and M5x0.8 port, it operates between 30-500mm/s. Note this specific SKU lacks a piston magnet, so position sensing is not supported without upgrading to the -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD25X75 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD25X75 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 75 mm |
| Acting type | Double acting, rod both ends |
| Port size | M5×0.8 |
| Rod end thread | M5×0.8 female / M8×1.25 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 (Ø25mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 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 SDAD25X75 Is Used
Symmetric Transfer Arms
Drives a pick-and-place arm from one end while the opposite rod end mounts a mechanical stop, utilizing the 206.2N equal force for stable part shuttling.
Balanced Lift Stations
Lifts 10.5kg vertical payloads smoothly using the 75mm stroke, relying on the through-rod to resist twisting during elevation.
Dual-End Sealing Jigs
Compresses packaging flaps simultaneously from both rod ends, taking advantage of the compact riveted body to fit narrow conveyor frames.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD25X75 the Right Cylinder?
When sizing this unit, compare it against adjacent bores: the SDAD20 yields 131.9N at 0.5MPa, while the SDAD32 provides 345.6N. The 25mm bore hits a practical middle ground, offering a safe working load of roughly 124N or a vertical lift capacity of about 10.5kg with a 2:1 safety margin. Choose this if your application requires symmetric force and dual-end tooling.
The through-rod geometry allows driving a tool on one end while mounting a dog or fixture on the opposite side. Remember that a standard cylinder drifts when air pressure is lost or the valve centers; use an external rod lock or pilot-operated check valve for load holding. This configuration includes a 75mm stroke, M5x0.8 port, female M5x0.8 rod threads, and no magnet.
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 SDAD25X75 FAQ
Because it is a double-rod cylinder, the push and pull forces are identical. It generates 206.2N at 0.5MPa, 288.6N at 0.7MPa, and a maximum theoretical force of 42kgf at 1.0MPa in both directions.
Yes, the through-rod design allows tooling on one end and a dog on the opposite end. However, this specific SKU lacks a piston magnet, so it cannot trigger magnetic reed or electronic switches; you would need the -S variant for position sensing.
